fa91da4992 drivers: eth: gmac: only keep a reference to the packet when PTP is used
The SAM GMAC Ethernet driver currently keeps a reference to the packet
being sent in addition than keeping of references of the fragments. In
practice this is only needed when PTP is enabled, otherwise the driver
only need to prevent the fragment (or even their content) to be changed.

757d86b241 drivers: eth: gmac: keep a reference to the packet fragments
The SAM GMAC Ethernet driver uses scatter gather DMA to transmit data.
Each fragment of a network packet is mapped from a set of descriptors
that is used by the controller to do the DMA transfer. This means that
the packet is not necessary sent when the send() function returns. For
that reason the driver calls net_pkt_ref() on the packet to prevent it
from being freed. It is then unreferenced with net_pkt_unref() in the
TX ISR when the packet has effectively been sent.

However this doesn't work if the packet is modified in the meantime,
like it will be done in PR #12563 to remove the Ethernet header
contained in the first fragment. To avoid that, call net_pkt_frag_ref()
on each fragment of the packet, and unreferenced them with
net_pkt_frag_unref() in the TX ISR when the packet has effectively been
sent.

Default PWM instances are also enabled on Nordic DK boards so that it
is possible to build the basic fade_led sample for them without extra
adjustments.

After the above changes are applied, some configuration alterations
in basic samples blink_led and fade_led become no longer needed.
These are removed. And the blink_led sample is corrected so that it
works with the nRF HW PWM driver as well.

To avoid confusion, callbacks using ordinal pin numbers

This allows the shared_irq driver to be configured by device tree.
With previous implementation, only the board configuration can

than "config". With this patch, the driver can be fully configued at

666cf22c60 arch: allow system clock driver selection for cortex m
The selection of the Cortex M systick driver to be used
as a system clock driver is controlled by
CONFIG_CORTEX_M_SYSTICK.

To replace it by another driver CONFIG_CORTEX_M_SYSTICK
must be set to 'n'. Unfortunately this also controls
the interrupt vector for the systick interrupt. It is
now routed to __reserved. More bad the interrupt vector
can not be set by IRQ_CONNECT as it is one of the hard
coded interrupts in the interrupt table.

Route the hard coded systick interrupt to z_clock_isr
and make z_clock_isr a weak symbol that can be overwritten
by an alternative systick system clock driver.

d75495709d drivers: gpio: fix mis-use of slist API in callback processing
The iterator over registered callbacks failed to account for the
possibility that the callback would remove itself from the list.  If
this occurred any remaining callbacks would no longer be reachable from
the node.  Switch to the slist iterator that is safe for self-removal.

Note that the slist API remains unsafe for removal of subsequent nodes.
Even with the corrected code removal of the next callback registration
(cached in tmp) will result in it being called anyway, with the
remaining unremoved registrations not being called.  If the next
callback were removed and re-registered on a different device, the
callbacks would be invoked for the wrong device.

Resolve this by a documentation change describing the conditions under
which a change to callback registration from within a callback are
permitted.  Add a similar note regarding the effect of adding a
callback.  The current event invocation behavior for callbacks added
within an event is explicitly left unspecified, though in the current
slist implementation newly added callbacks will not be invoked until the
next event.

Closes #10186

f1619beab9 drivers: wifi: simplelink: socket() should return non-zero fds
simplelink_socket() is not returning non-zero socket file descriptors
when it succeeds. This leads to socket() to always return socket fd 0,
even when the network processor returns a non-zero fd.

This commit fixes simplelink_socket() to return the correct socket fd
when it succeeds in getting one from the network processor.

Fixes #12650

d0afacc6b4 display: ssd1673: replace k_busy_wait by k_sleep
The SSD1673 driver currently use k_busy_wait to wait for the
controller to finish the execution of a commmand. However a display
update command can take from a few hundreds of ms (default LUT) to
almost a second (initial LUT). k_busy_wait is just a spinning loop,
which prevents all the threads with lower priority to not be executed
during that time. That could be the case for example of the shell or
the log thread.

As the timing is not critical, it's better to use k_sleep instead,
allowing the CPU to process other threads. In the long term it might
even be better to use an interrupt there, but might not be that easy if
we want to support to various SoCs that can be connected to such a
display.

4fcab1ef1a drivers: modem: wncm14a2a: wait for modem init
During development of the WNC-M14A2A modem driver, I felt like the
initialization took too long to make the user wait.  However, due
to the addition of other drivers such as OpenThread where delays
during startup are noticable, the modem startup time isn't so bad.

Let's remove the delay work which allows Zephyr to startup before
the modem is fully initialized.

NOTE: This also fixes a long standing bug where samples using the
modem would never know when it was ready (without waiting for the
interface up event).  This change makes it always ready once the
sample starts.

d144639e47 drivers: eth: gmac: use non-cached memory for descriptor lists
Atmel SAM Ethernet module is using a scatter-gather technique to
exchange data with the Ethernet driver. To communicate the location
of the data buffers the driver sets-up a so called descriptor list. This
is effectively a place in RAM containing a sequence of 32-bit words
representing buffer location and its status.

Currently the cache coherency is handled using cache clean or
invalidate. Unfortunately this strategy only works correctly when the
corresponding data size is a multiple of the cache line. This is not
the case here and might lead to data loss or corruption.

Instead of using cache operations, this patch moves the descriptor
listed to the recently added non-cached memory region, as recommended by
ATMEL. A data synchronisation barrier is still required for writes, as
the non-cached memory is defined with TEX=1, i.e. it is not strongly
ordered. The descriptor lists alignment can be decreased to 4 bytes, as
required by the SAM Ethernet module.

The RX/TX buffer are left unchanged, still managed by cache operations.

The SAM E70 GMAC ethernet driver reference a packet with net_pkt_ref()
when queueing a packet, and unreference it with net_pkt_unref() in the
ISR when it has been fully sent.

The call to net_pkt_ref() is done just after re-enabling the
interruptions, so there is however a small race condition that might
cause the packet to be unreference before being referenced. This is
only theoretical and has not been seen in practice.

The OpenISA RV32M1 SoC has four CPU cores. Two of these are RISC-V
32-bit cores, which are named "RI5CY" and "ZERO-RISCY". (The other two
cores are ARM Cortex-M0+ and -M4.) This patch adds basic SoC
enablement for the RISC-V cores:

- basic dtsi, to be extended as additional drivers are added
- SoC definition in soc/riscv32/openisa_rv32m1 for RI5CY / ZERO-RISCY
- system timer driver for RI5CY, based on LPTMR0 peripheral

The timer driver will be generalized a bit soon once proper
multi-level interrupt support is available.

Emphasis is on supporting the RI5CY core as the more capable of the
two; the ZERO-RISCY SoC definitions are a good starting point, but
additional work setting up a dtsi and initial drivers is needed to
support that core.

0aa87e15bb drivers: interrupt_controller: multi-level improvements
Some extensions to the multi-level interrupt controller are required
to support SoCs with more than four level 2 interrupt "aggregators".

Extend existing support to allow at most 8 level 2 or level 3
aggregators. Use Kconfig macro templates to cut down on boilerplate.
Try to clarify some aspects of the Kconfig help while we're at it, and
change the type of options which count things or are table offsets
from "hex" to "int", so that the generated .config is easier to read.

Finally, make some improvements to gen_isr_tables.py while we are
here. In particular, move some assignments around to cut down on
duplicated work, don't check for symbols we know must exist, and
improve the debug logging output's readability.

084363a0dc drivers: timer: nrf: refactor for speed and correctness
The existing implementation of z_clock_set_timeout() calculates the
compare value based on a complex series of operations including an
unconditional integer division and multiplication intended to ensure the
compare value is aligned to a tick boundary.  On the nRF51 this division
requires a call to an outline function with a data-dependent execution
time.

In the common case where the timeout is set less than one tick past the
last observed tick the devision can be elided, as can several extra
operations intended to deal with fractional ticks.

The code also failed to account for a ticks-per-cycle that violated the
minimum delay required to guarantee a compare value would result in a
match without wrapping.  The minimum delay was also unreasonably long
(about 1 ms).  Reduce it to a more reasonable value to allow for a
higher ticks-per-second, and diagnose attempts to set the tick frequency
above the supported maximum (8192 Hz).

Finally, move the parts of the compare calculation that are not
dependent on the live counter value out of the locked region.

Prior to this change the observed time between the irq_lock() and
irq_unlock() in z_clock_set_timeout() on the nRF51 ranged between 5 us
and 8 us.

With the revised algorithm the observed lock duration is between 2.16 us
(1024 Hz) and 2.88 us (100 Hz) in the common case that the compare is
set within the current tick.  If the compare is set late the duration
will be higher, but no greater than the previous implementation.

87cf468959 drivers: eth: gmac: fix TX descriptor write process
The SAM E70 Ethernet driver uses scatter gather DMA to transmit data.
Each fragment of a network packet is mapped from a set of descriptors
that is used by the controller to do the DMA transfer. Each descriptor
contain an address and a length/status. The important status bits are
GMAC_TXW1_LASTBUFFER to indicate the last fragment of a packet and
GMAC_TXW1_USED to indicate that a descriptor has been processed by the
controller.

When starting a transmission, the controller start at the descriptor
after the last one that has been processed. If the descriptor is NOT
flagged by GMAC_TXW1_USED, it sends a first packet by sending all the
fragments up to a descriptor flagged with GMAC_TXW1_LASTBUFFER. The
first descriptor of a packet *and only the first descriptor of a packet*
is then modified to flag it with GMAC_TXW1_USED and to provide a status
(mostly related to errors and checksum offloading). It then continues
with the next packet and so on and only stops if the next descriptor
after GMAC_TXW1_LASTBUFFER is flagged with GMAC_TXW1_USED.

Therefore in order for the controller to stop processing descriptors,
the strategy is to flag the next descriptor after the last fragment to
be sent with GMAC_TXW1_USED. When the next packet has to be queued, the
flag can be removed before starting a transmission.

This is what is currently done in the current driver. However there is a
small race condition in the implementation: if packets are queued fast
enough, the controller is still sending the fragment of the previous
packet when the descriptor are written. When writing the first
descriptor, the GMAC_TXW1_USED flag is removed. This is done after
writing the address (with a memory barrier) so that looks safe. However
given that the GMAC_TXW1_USED flag is only added by the controller to
the first descriptor of a packet it means the next descriptor might
have it cleared. In that case the descriptor is processed, and a junk
packet is sent. That also desynchronize eth_tx and tx_complete as one
or more packets than expected are transmitted.

In order to fix that the strategy is slightly changed to initially write
the first descriptor with the GMAC_TXW1_USED flag set. Once all the
descriptors from the packet are written the bit is cleared (after a
memory barrier). Then the transmission can be started safely.

The patch also does a small optimization writing the next descriptor
with only the GMAC_TXW1_USED bit set instead of setting this bit. As
this will be a non-cached area, it's better avoiding a read followed
by a write if not necessary.

afbee4c96a drivers: eth: gmac: conservatively compute the number of descriptors
If a pkt has more frags than the number of TX descriptors, we end up in
a deadlock situation, as the whole packet and thus all the frags have to
be mapped in the descriptors at once. That is why the number of
descriptors is defined as CONFIG_NET_BUF_TX_COUNT + 1.

This wrongly assumes that only TX buffers can be used to send data,
however the packets might also come from the RX buffers, like for
example with ICMPv4.

Therefore define the number of descriptors as the maximum of
CONFIG_NET_BUF_RX_COUNT + 1 and CONFIG_NET_BUF_TX_COUNT + 1. This fixes
a deadlock when CONFIG_NET_BUF_TX_COUNT is much smaller than
CONFIG_NET_BUF_RX_COUNT.

18b07e09e0 drivers: eth: gmac: drop TX timeout handling
The current SAM E70 Ethernet driver sometimes get stuck if the stack
has to send 2 packets in a row, for example an ack for the just received
data + answer data.

The problem is the following one:
1) The first packet goes through eth_tx, one tx_desc_sem semaphore is
   taken, and the tx_timeout_work delayed work is submitted.
2) The second packet also goes through eth_tx, another tx_desc_sem
   semaphore is taken, and the tx_timeout_work delayed work is not
   started because there is already one already submitted.
3) The first packet has been sent, one tx_desc_sem semaphore is given
   and the tx_timeout_work delayed work is cancelled.
4) The second packet has been sent but given the delayed work has
   already been cancelled, tx_completed is not called: the tx_desc_sem
   semaphore is not given back and the network packet is not
   unreferenced.

The whole timeout concept probably has to be reworked. In the meantime
it is probably better to just drop the timeout code instead of keeping
the driver broken. We can only get stuck on the TX path if there is a
bug in the driver or a hardware malfunction. It might happen, but with
the less probability then the current hangs. In addition it just hides
the real issues and prevent them to be fixed.

This commit therefore just remove the timeout code in the TX path.

The SimpleLink wifi driver enables the Fast Connect method of
WiFi provisioning, which allows the network coprocessor to
reconnect to a previously connected Access Point (AP) on
startup.

Previously, if Fast Connect failed to connect, any network
socket applications would inevitably fail, as there would have
been no wifi connection.

This patch adds a configurable timeout for the Fast Connect
feature, after which timeout, an error is logged informing
the user to manually reconnect to an AP.

Reconnection is typically accomplished by separately running the
wifi sample shell program.

c885cb533e net: buf: linearize: Get rid of useless memset()
net_buf_linearize() used to clear the contents of output buffer,
just to fill it with data as the next step. The only effect that
would have is if less data was written to the output buffer. But
it's not reliable for a caller to rely on net_buf_linearize() for
that, instead callers should take care to handle any conditions
like that themselves. For example, a caller which wants to process
the data as zero-terminated string, must reserve a byte for it
in the output buffer explicitly (and set it to zero).

The only in-tree user which relied on clearing output buffer was
wncm14a2a.c. But either had buffer sizes calculated very precisely
to always accommodate extra trailing zero byte (without providing
code comments about this), or arguably could suffer from buffer
overruns (at least if data received from a modem was invalid and
filled up all destination buffer, leaving no space for trailing
zero).

b69d0da82d arch/x86_64: New architecture added
This patch adds a x86_64 architecture and qemu_x86_64 board to Zephyr.
Only the basic architecture support needed to run 64 bit code is
added; no drivers are added, though a low-level console exists and is
wired to printk().

The support is built on top of a "X86 underkernel" layer, which can be
built in isolation as a unit test on a Linux host.

Limitations:

+ Right now the SDK lacks an x86_64 toolchain.  The build will fall
  back to a host toolchain if it finds no cross compiler defined,
  which is tested to work on gcc 8.2.1 right now.

+ No x87/SSE/AVX usage is allowed.  This is a stronger limitation than
  other architectures where the instructions work from one thread even
  if the context switch code doesn't support it.  We are passing
  -no-sse to prevent gcc from automatically generating SSE
  instructions for non-floating-point purposes, which has the side
  effect of changing the ABI.  Future work to handle the FPU registers
  will need to be combined with an "application" ABI distinct from the
  kernel one (or just to require USERSPACE).

+ Paging is enabled (it has to be in long mode), but is a 1:1 mapping
  of all memory.  No MMU/USERSPACE support yet.

+ We are building with -mno-red-zone for stack size reasons, but this
  is a valuable optimization.  Enabling it requires automatic stack
  switching, which requires a TSS, which means it has to happen after
  MMU support.

+ The OS runs in 64 bit mode, but for compatibility reasons is
  compiled to the 32 bit "X32" ABI.  So while the full 64 bit
  registers and instruction set are available, C pointers are 32 bits
  long and Zephyr is constrained to run in the bottom 4G of memory.

011a88c744 ext: mcux: Update to MCUXpresso SDK 2.5.0
Updates the MCUXpresso SDK to version 2.5.0 for applicable SoCs.
Wireless (KW*) and legacy (KL25) SoCs were not included in this
MCUXpresso SDK release and are therefore not updated here.

New in this release is SoC-level and board-level support for external
xip flash in the i.MX RT family.

For RT1050, we are now using the MCUXpresso SDK for the EVKB version of
the board, which correponds to an upgrade from A0 to A1 silicon.
However, we don't yet have Kconfigs in place to support A1 silicon part
numbers, and therefore add a simple cmake hack to convert A0 part
numbers to A1 part numbers.

The SDK flash driver interface also changed slightly in this release,
and thus the zephyr flash shim driver is updated accordingly.

Origin: MCUXpresso SDK
License: BSD 3-Clause

In general synchronisation between memory and the instruction cache
should be done explicitly, for example this is how it is done for RAM.
It is also done that way for flash writes in the current STM32 flash
driver.

However in case of flash erases, the current STM32 flash driver flushes
the i-cache. It probably doesn't make a big difference for the
Cortex-M3/M4 families as the cache is very small. That said it might
have bigger impact on families based on Cortex-M7 as it has between 4KB
and 16KB of i-cache, that will be added latter in this patch serie.

This patch therefore remove the i-cache flush in
flash_stm32_flush_caches.

8e356dbc88 drivers: flash: stm32: improve timeout handling
The timeout handling in the STM32 flash driver is currently a counter
in the busy check loop. This doesn't scale well across the whole STM32
family:
- The duration of the loop depends on the CPU speed, the activation of
  caches.
- The duration of the longest flash operation (a sector erase as the
  driver doesn't support mass erase) can varies a lot mostly depending
  on the sector size, 2K on F0 and L4 families or 128K on the F4 family.

In addition the timeout can change depending if the writing thread is
prempted or not.

Fix that by defining a timeout in ms depending on the family, and using
k_uptime_get to get a precise measurement of the time.

bff65b6330 net/ethernet: Let's remove the use for ll reserve
There is no need to reserve any space for each frag, as the l2 will
allocate a frag for the ethernet header, arp will do the same.

This is one step further to removing the concept of ll reserve.

0187d60937 drivers: adc_mcux: improve initialization of the ADC
Improve initialization of the ADC.

After initialization with the default values, the clock source
of the ADC is asynchronous clock (ADACK) and clock divide ratio
is 8. The minimum conversion clock frequency is 1MHz.
Add clock divider selection and set default divide ratio to 1.
That sets the conversion clock frequency to approximately 5MHz.

Default configuration for the voltage reference is set to
external pins V_REFH and V_REFL. Depending on the MCU configuration
V_REFL may be connected to ground and V_REFH to VREF_OUT.
Since Voltage Reference block is not supported, the ADC does not work
properly on FRDM-KW41Z. Add voltage reference selection to fix it.

Enable self-calibration function as recommeded in Reference Manual.

3134468801 drivers: gpio: nrfx: fix lost level interrupts
Nordic devices detect edge interrupts through the PORT event which is
generated on a rising edge of DETECT, which itself is asserted when any
GPIO is configured for sense level detection and the GPIO's input signal
matches the configuration.

The previous code in Zephyr attempts to detect when at least one GPIO
SENSE signal is still asserted, and intentionally leaves the PORT event
uncleared to ensure the interrupt is re-entered.

This approach fails when no pin satisfies its SENSE condition during the
check but at least one input changes level between the completion of the
check and the clear of the PORT event.  Such a failure can be observed
on the pca20020 hardware when multiple sensors configured for level
triggers are active.  In this situation the corresponding sensor trigger
signals remain asserted but the PORT event required to drive their
processing has already been cleared.

The fix is to ensure that the SENSE configuration for all GPIOs across
all port instances is disabled prior to unconditionally clearing the
PORT event, then re-enabling the SENSE configuration for all GPIOs once
callbacks associated with detected SENSE triggers have been performed.
The act of re-enabling will ensure any relevant SENSE condition causes a
new rising edge on DETECT and so a new PORT event.

Closes issue #11806

cffb2d8051 drivers: ethernet: Add TI Stellaris ethernet controller driver.
The driver can be tested using different networking emulation
approaches.

This approach will work across multiple Qemu instances. There can be
more than one Qemu instance, run using the following command. They
would appear to be on the same Ethernet network.

  $ qemu-system-arm -M lm3s6965evb                      \
                    -serial stdio                       \
                    -net nic                            \
                    -net socket,mcast=230.0.0.1:1234    \
                    -kernel zephyr.elf

This approach will work with other virtualization technologies that
support connecting to a VDE switch, like VirtualBox and User Mode
Linux. The switch can be started using the following command.

  $ vde_switch --sock /tmp/switch

Qemu can be connected to the switch using the following command.

  $ qemu-system-arm -M lm3s6965evb                      \
                    -serial stdio                       \

This effectively reverts part of earlier 49bb163756 which moved
interrupt acknowledgement until after return from the user callback.
This was done confusing the flow of this driver with how some other
drivers do it, where pending interrupt status is checked by
uart_irq_rx_ready()/uart_irq_tx_ready(), which should be called by
the callback. But the uart_cmsdk_apb driver actually uses different
hardware register in these functions. And acking IRQs after user
callback can lead to race condition and losing an IRQ, and the
simple fix in this case is just move acknowledgement to where it
was before.

55674d8e17 drivers: usb: nordic: change USBD driver locking scheme
Nordic USB driver shim uses nrfx_usbd driver from nrfx package.
The driver was protected by a semaphore during every transfer
to prevent access from multiple threads at the same time.
This leads to the problem when a class schedules transfer on one
endpoint before host asks for the data (to be sent later) - driver
is locked and other endpoints (including control EP) are blocked.
Currently, only driver calls are wrapped with semaphore without
waiting for the transfer to complete, allowing scheduling transfers
on different endpoints. This is allowed bu nrfx_usbd, however
shim prevents user from scheduling multiple transfers on one
EP (required by nrfx_usbd).

759b987f72 drivers: serial: Update cc32xx uart interrupt handling
The Zephyr console and shell interrupt processing assumes
a TX interrupt is evoked upon first enabling the TX
interrupt via uart_irq_tx_enable.

This was not the case with the cc32xx uart, coming out of
reset, with FIFO's disabled.

The only way found to achieve this behavior is to fill
the fifo with a non-printable character on initialization.

Also, the uart driver was explicitly clearing TX/RX interrupts in
its isr, which was unnecessary, as the act of reading/writing
did that implicitly.

These fixes allow the cc32xx uart to work with the
current Zephyr console/shell design.

49bb163756 drivers: serial: uart_cmsdk_apb: Fix interrupt-driven operation
1. There's an expectations that TX ready (i.e. TX buffer space
available) interrupt is a level interrupt, i.e. always active
while there's TX buffer space available. In particular, there's
an expectation that after uart_irq_tx_enable(), the TX interrupt
will immediately fire (assuming free TX buffer space is available).
But CMSDK UART interrupt appears to be edge interrupt, firing only
on buffer state change. So, after irq_tx_enable(), we need to
"bootstrap" interrupt processing by calling user-defined ISR
manually (the ISR will see that TX ready to accept a new char,
will write it there, then we'll get interrupt once TX buffer is
ready again).

2. Interrupts should be acknowledges only after user ISR is called,
because the ISR will check the status of interrupts.

3. Update stale comments.

To handle other NOR flash a flash id table (as Linux do) which contains

introduced.
We currently support the following flash:
 - W25Q80
 - W25Q16
 - W25Q32
 - S25FL216K
 - MX25UM512

The read and write functions are able to handle more then one page at a
time and return the number of bytes read or write.
Also because every NOR flash expect to disable the write protection
before writing or erasing, the write enable command is now part of the
write and erase functions.

39b2a09f38 drivers/timer: New xtensa timer with tickless support
Rewritten Xtensa CCOUNT driver along the lines of all the other new
drivers.  The new API permits much smaller code.

Notably: The Xtensa counter is a 32 bit up-counter with a comparator
register.  It's in some sense the archetype of this kind of timer as
it's the simplest of the bunch (everything else has quirks: NRF is
very slow and 24 bit, HPET has a runtime frequency detection, RISC-V
is 64 bit...).  I should have written this one first.

Note also that this includes a blacklist of the xtensa architecture on
the tests/driver/ipm test.  I'm getting spurious failures there where
a k_sem_take() call with a non-zero timeout is being made out of the
console output code in interrupt context.  This seems to have nothing
to do with the timer; I suspect it's because the old timer drivers
would (incorrectly!) call z_clock_announce() in non-interrupt context
in some contexts (e.g. "expiring really soon").  Apparently this test
(or something in the IPM or Xtensa console code) was somehow relying
on that on Xtensa.  But IPM is a Quark thing and there's no particular
reason to run this test there.

Rewritten driver along the lines of all the other new drivers,
implementing the new timer API.  Structurally, the machine timer is an
up-counter with comparator, so it works broadly the same way HPET and
NRF do.  The quirk here is that it's a 64 bit counter, which needs a
little more care.

Unlike the other timer reworks, this driver has grown by a few lines
as it used to be very simple.  But in exchange, we get full tickless
support on the platform.

Fixes #10609 in the process (the 64 bit timer registers are unlatched
for sub-word transfers, so you have to use careful ordering).

select tickless mode's default automatically on drivers that support
it (rather than having to set the default per-board).  Select it from

0f444c84e5 drivers/timer: Add a standard workaround for known qemu issues
Qemu doesn't like tickless.  By default[1] it tries to be realtime as
vied by the host CPU -- presenting read values from hardware cycle
counters and interrupt timings at the appropriate real world clock
times according to whatever the simulated counter frequency is.  But
when the host system is loaded, there is always the problem that the
qemu process might not see physical CPU time for large chunks of time
(i.e. a host OS scheduling quantum -- generally about the same size as
guest ticks!) leading to lost cycles.

When those timer interrupts are delivered by the emulated hardware at
fixed frequencies without software intervention, that's not so bad:
the work the guest has to do after the interrupt generally happens
synchronously (because the qemu process has just started running) and
nothing notices the dropout.

But with tickless, the interrupts need to be explicitly programmed by
guest software!  That means the driver needs to be sure it's going to
get some real CPU time within some small fraction of a Zephyr tick of
the right time, otherwise the computations get wonky.

The end result is that qemu tends to work with tickless well on an
unloaded/idle run, but not in situations (like sanitycheck) where it
needs to content with other processes for host CPU.

So, add a flag that drivers can use to "fake" tickless behavior when
run under qemu (only), and enable it (only!) for the small handful of
tests that are having trouble.

[1] There is an -icount feature to implement proper cycle counting at
the expense of real-world-time correspondence.  Maybe someday we might
get it to work for us.

20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

9892f40204 gpio: stm32 use dts extracted information to populate gpio instances.
The information extracted from the device tree is now used to initialize
GPIO device instances. Up until now the GPIO device driver made no use
of this information. Actual instance creation is still controlled using
the Kconfig method. Missing GPIO device tree nodes were added in the
process for STM32L073, STM32F413 and STM32F373.

The information for gpio instance initialization has already been
present for supported STM32 SoCs but remained unused. Changes in the
device tree had no effect on GPIO functionality and was essentially
redundant. Using the device tree for hardware description seems
plausible and less painful than a myriad of defines in some SoC
description header.

The change was implemented under the assumption that current device
trees provide a correct description of the SoCs. Base register addresses
and RCC register bits were not explicitly checked for each device.

Manual tests were executed on:
	- NUCLEO-F103RB
	- STM32F429I-DISCO
	- STM32F746G-DISCO
	- NUCLEO-F767ZI

Manual tests consisted of blinky on different GPIOs and pins on each
board.

sanitycheck was executed for all STM32 based boards

cb53a1a2d5 drivers: clock_control: Remove asserts that break LF clock on nRF5
There are two asserts in the ISR for clock events on the nRF5 that
appear to be accidental.

The first assert fails if there are any LF clock started events, which
there will be when starting up the RC oscillator with calibration.

The second assert fails when we decrement the refcount on the HF
oscillator after finishing a calibration. There will typically be
users left of the HF oscillator, so _m16src_stop() doesn't actually
stop it and thus doesn't return 0.

This code typically works fine because it's not built with asserts
enabled by default. Can be reproduced on a BBC microbit with the
default config plus CONFIG_ASSERT=y.

42a38e1172 drivers: entropy: nrf5: Fix hardware state management
The entropy_nrf5_get_entropy_isr(...,  ENTROPY_BUSYWAIT)
unconditionally started and stopped hardware random number generator
disrupting management of random data pools implemented by the driver.

Moreover, simultaneous call to mentioned function from different
priorities led to hangup of lower priority call as hardware was
stopped by higher priority call while the other one waited for data.

This commit solves mentioned problems by moving the responsibility
for stopping hardware to the interrupt handler. As result hardware
is stopped only when there is no blocking calls to the
entropy_nrf5_get_entropy_isr() as well as all random data pools
are full.

This commit also fixes interrupt management in the mentioned
function, as previous implementation unconditionally enabled
interrupt causing problems similar to the described above.

060b8c1512 drivers: ssd1306: fixup dts support
A few issues with the dts support for the SSD1306 display driver:
1. binding file mixed description & generation up together
   - rename most uses of generation to description and add proper
     generation field into yaml
2. Drop use of BASE_LABEL, this shouldn't be used by most bindings
3. dts defines that are being assumed in driver aren't correct.  We
   should be using a dts_fixup.h in the sample to map the generated
   defines to those used in the driver.  We remove the incorrect
   defines that the driver assumes right now.
4. Fixup 'segment-remap' and 'com-invdir' properties that are booleans
   in the binding file and associated code changes.

987c0e5fc1 kernel: New timeout implementation
Now that the API has been fixed up, replace the existing timeout queue
with a much smaller version.  The basic algorithm is unchanged:
timeouts are stored in a sorted dlist with each node nolding a delta
time from the previous node in the list; the announce call just walks
this list pulling off the heads as needed.  Advantages:

* Properly spinlocked and SMP-aware.  The earlier timer implementation
  relied on only CPU 0 doing timeout work, and on an irq_lock() being
  taken before entry (something that was violated in a few spots).
  Now any CPU can wake up for an event (or all of them) and everything
  works correctly.

* The *_thread_timeout() API is now expressible as a clean wrapping
  (just one liners) around the lower-level interface based on function
  pointer callbacks.  As a result the timeout objects no longer need
  to store backpointers to the thread and wait_q and have shrunk by
  33%.

* MUCH smaller, to the tune of hundreds of lines of code removed.

* Future proof, in that all operations on the queue are now fronted by
  just two entry points (_add_timeout() and z_clock_announce()) which
  can easily be augmented with fancier data structures.

96013b0375 system_timer.h: Change "now" uptime API to be simpler for drivers
The current z_clock_uptime() call (recently renamed from
_get_elapsed_program_time) requires the driver to track a full 64 bit
uptime value in ticks, which is entirely separate from the one the
kernel is already keeping.

Don't do that.  Just ask the drivers to track uptime since the last
call to z_clock_announce(), since that is going to map better to
built-in hardware capability.

Obviously existing drivers already have this feature, so they're
actually getting slightly larger in order to implement the new API in
terms of the old one.  But future drivers will thank us.

Ideally we'd have a header-level interface definition for individual

722a888ef7 timer: Clean up hairy tickless APIs
The tickless driver had a bunch of "hairy" APIs which forced the timer
drivers to do needless low-level accounting for the benefit of the
kernel, all of which then proceeded to implement them via cut and
paste.  Specifically the "program_time" calls forced the driver to
expose to the kernel exactly when the next interrupt was due and how
much time had elapsed, in a parallel API to the existing "what time is
it" and "announce a tick" interrupts that carry the same information.

Remove these from the kernel, replacing them with synthesized logic
written in terms of the simpler APIs.

In some cases there will be a performance impact due to the use of the
64 bit uptime call, but that will go away soon.

ab488277bc drivers/timer: Unify timeout setting APIs
The existing API had two almost identical functions: _set_time() and
_timer_idle_enter().  Both simply instruct the timer driver to set the
next timer interrupt expiration appropriately so that the call to
z_clock_announce() will be made at the requested number of ticks.  On
most/all hardware, these should be implementable identically.

Unfortunately because they are specified differently, existing drivers
have implemented them in parallel.

Specify a new, unified, z_clock_set_timeout().  Document it clearly
for implementors.  And provide a shim layer for legacy drivers that
will continue to use the old functions.

Note that this patch fixes an existing bug found by inspection: the
old call to _set_time() out of z_clock_announce() failed to test for
the "wait forever" case in the situation where clock_always_on is
true, meaning that a system that reached this point and then never set
another timeout would freeze its uptime clock incorrectly.

fa99ad66d0 sys_clock: Fix up tick announce API
There were three separate "announce ticks" entry points exposed for
use by drivers.  Unify them to just a single z_clock_announce()
function, making the "final" tick announcement the business of the
driver only, not the kernel.

Note the oddness with "_sys_idle_elapsed_ticks": this was a global
variable exposed by the kernel.  But it was never actually used by the
kernel.  It was updated and inspected only within the timer drivers,
and only so that it could be passed back to the kernel as the default
(actually hidden) argument to the announce function.  Break this false
dependency by putting this variable into each timer driver
individually.

317178b88f sys_clock: Fix unsafe tick count usage
The system tick count is a 64 bit quantity that gets updated from
interrupt context, meaning that it's dangerously non-atomic and has to
be locked.  The core kernel clock code did this right.

But the value was also exposed to the rest of the universe as a global
variable, and virtually nothing else was doing this correctly.  Even
in the timer ISRs themselves, the interrupts may be themselves
preempted (most of our architectures support nested interrupts) by
code that wants to set timeouts and inspect system uptime.

Define a z_tick_{get,set}() API, eliminate the old variable, and make
sure everyone uses the right mechanism.

Properly, these should be an API defined by the timer driver (who

bdde886ed5 led_strip: ws2812: HACK: memory-hungry pulse timing bugfix
At least on nRF52 devices, we are taking too much time between pixels
dealing with overhead inside the SPI driver transceive calls. This is
leading to dropped frames, because the dead time between frames is
long enough (5000ns+) to look like a reset pulse to the LED strip.

Given this SPI driver limitation, it seems this LED driver's design
decision to rely on SPI peripherals as efficient pulse generators
doesn't work well in practice.

The right way to handle this is probably to switch from SPI to
efficient inline assembly which bit-bangs the pulses with interrupts
disabled.

This is what other efficient libraries do to drive this type of
LED (e.g. FastLED uses C++ templates that expand into such
assembly). The Zephyr GPIO API doesn't support doing that in a
portable fashion, unfortunately.

For now, we'll cheat by pre-allocating enough buffer space to send the
entire strip's worth of data.

This is preposterously inefficient (8x memory overhead since there's
one byte to make a SPI frame for each bit of color), but makes the
driver work correctly.

(Note that using timer peripherals as pulse generators, when combined
with DMA for efficiency, would also lead to similar levels of
overhead.)

5d8834bee4 driver: sensor: Add support for LIS2MDL Mag sensor
Added support to LIS2MDL Magnetometer sensor provided
with following features:
	- I2C interface
	- Mag data
	- Temperature data
	- ODR configurable by config or at runtime
	- Trigger mode selectable by menuconfig
	- IRQ pin configurable (by dts or Kconfig)
	- Hard Iron offset setting at runtime
	- Include yaml file

Tested on ST MEMS IKS01A2 + NUCLEO STM32F411RE board.
LIS2MDL connected to I2C master interface (SPI 3 wire not
supported yet).
Test run with all ODR {10, 20, 50, 100} Hz in poll and
trigger mode.

GPIO IRQ dts configuration has been tested by adding
to boards/arm/nucleo_f411re/nucleo_f411re.dts file
this patch:

&i2c1 {
        status = "ok";
        clock-frequency = <I2C_BITRATE_FAST>;
+
+       /* ST Microelectronics LIS2MDL mag sensor */
+       lis2mdl-magn@1e {
+               compatible = "st,lis2mdl-magn";
+               reg = <0x1e>;
+               irq-gpios = <&gpioa 4 0>;
+               label = "LIS2MDL";
+               status = "ok";
+       };
};

and adding boards/arm/nucleo_f411re/dts.fixup with following
content:

	ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_LABEL

7b82e9f2d0 drivers: i2s: Add support for I2S stm32
STM32 I2S driver implementation. It has been designed in the most
generic way possible, with the possibility of using it in master/slave
and rx/tx mode. Currenty it has been tested for master rx mode only
using the microphone on ArgonKey board.

The configuration file permits to compile it for STM32F4xx product
family only, but it should be easy to extend it also for other
families.

It supports all 5 STM32F4xx I2S controllers (I2S 1/4/5 on APB2 and
I2S 2/3 on APB1).
It makes uses of the available DMA channels for rx/tx streams.

The clock source can be selected among one of the following two choices:

  - PLLI2S pll, with possibility to configure PLLM/PLLN/PLLR
  - HSE/HSI clock

Interrupt is triggered only in case of errors (FRM/OVR/UDR).

Previously, '\n' in LOG_DBG statements were added to
improve readability, by ensuring IP address weren't printed

But with the logging updates, '\n' is no longer

is automatically added, throwing off attempts at alignment.

This patch finally just removes the '\n''s from the log messages,
and cuts a few longer messages into separate messages.

Previously, the NWP (Network Coprocessor) was configured during

Since the SimpleLink "FastConnect" feature was added,
meaning an automatic reconnect can occur at this time, this
results in early callbacks into the network stack
before it was fully initialized, resulting in a NULL iface
ptr being sent in as argument.

Now, for safety, the NWP startup is moved later to iface_init,
where it more logically belongs.

the timer interrupt will be taken before the loop can
read the LOAD/VAL registers, but this is not architecturally

The sensor driver Kconfigs are sourced inside an "if SENSOR..endif"
conditional, so it is redundant for sensor drivers to explicitly

c0ce7d02d5 adc: Convert mcux adc16 driver to the new adc api
Major rework of the mcux adc16 driver to convert it to the new adc api.
Currently supports a subset of the api features including synchronous
and asynchronous reads, and consecutive reads triggered by the kernel
timer.

Does not yet support some of the channel configuration options such as
gain and reference voltage because the hardware only allows these
options to be configured by peripheral instance rather than by channel.
The values are currently hardcoded in the driver, but in the future we
could introduce some flexibility per instance via device tree
attributes.

Does not yet support consecutive reads triggered by a hardware timer.

f1891e9473 drivers: adc: Introduce reworked API
This commit replaces the API for ADC drivers with a reworked one.
As requested in the issue #3980, the adc_enable/adc_disable functions
are removed. Additionaly, some new features are introduced, like:
- asynchronous calls
- configuration of channels
- multi-channel sampling

Common parts of code that are supposed to appear in each implementation
of the driver (like locking, synchronization, triggering of consecutive
samplings) are provided in the "adc_context.h" file to keep consistency
with the SPI driver. Syscalls are no longer present in the API because
the functions starting read requests cannot use them, since they can be
provided with a callback that is executed in the ISR context, and there
is no point in supporting syscalls only for the channels configuration.

"adc_api" test is updated and extended with additional test cases,
with intention to show how the API is supposed to be used.
"adc_simple" test is removed as it does not seem to add much value.

8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/

17f1b0adec Kconfig: Switch to improved globbing statements
A design flaw of 'gsource' is that there's no way to require at least
one file to match the glob pattern. This could lead to silent errors.

Switch to a new design, where a plain 'source' is globbing and requires
at least one file to match. A separate 'osource' (optional source)
statement is available for cases where it's okay for a pattern (or plain
filename) to not match any files.

'orsource' combines 'osource' and 'rsource' (relative source).

This commit search-replaces 'gsource' with 'source', but backwards
compatibility with 'gsource' is still maintained by making it an alias
for 'osource' (and by making 'grsource' an alias for 'orsource').

The three Kconfig files arch/{nios2,posix,xtensa}/Kconfig source
arch/{nios2,posix,xtensa}/soc/*/Kconfig, which doesn't match any files.
Use 'osource' for those. The soc/*/Kconfig files seem to be for
additional SoC-specific symbols, only none exist yet on those ARCHes.

Also use 'osource' for the source of $ENV_VAR_BOARD_DIR/Kconfig in
boards/Kconfig, which doesn't exist for all boards.

This commit makes this function faster by removing redundant access

ec3eff57e0 Kconfig: Use the first default with a satisfied condition
Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.

There are at least three problems with the patch:

  1. It's inconsistent with how Kconfig works in other projects, which
     might confuse newcomers.

  2. Due to oversights, earlier 'range' properties are still preferred,
     as well as earlier 'default' properties on choices.

     In addition to being inconsistent, this makes it impossible to
     override 'range' properties and choice 'default' properties if the
     base definition of the symbol/choice already has 'range'/'default'
     properties.

     I've seen errors caused by the inconsistency, and I suspect there
     are more.

  3. A fork of Kconfiglib that adds the patch needs to be maintained.

Get rid of the patch and go back to standard Kconfig behavior, as
follows:

  1. Include the Kconfig.defconfig files first instead of last in
     Kconfig.zephyr.

  2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
     last in arch/Kconfig.

  3. Include arch/<arch>/soc/*/Kconfig first instead of last in
     arch/<arch>/Kconfig.

  4. Swap a few other 'source's to preserve behavior for some scattered
     symbols with multiple definitions.

     Swap 'source's in some no-op cases too, where it might match the
     intent.

  5. Reverse the defaults on symbol definitions that have more than one
     default.

     Skip defaults that are mutually exclusive, e.g. where each default
     has an 'if <some board>' condition. They are already safe.

  6. Remove the prefer-later-defaults patch from Kconfiglib.

Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions

As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).

This commit includes some default-related cleanups as well:

  - Simplify some symbol definitions, e.g. where a default has 'if FOO'
    when the symbol already has 'depends on FOO'.

  - Remove some redundant 'default ""' for string symbols. This is the
    implicit default.

Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).

Piggyback some fixes for style nits too, e.g. unindented help texts.

57286afdd6 drivers: uart: Allow to pass arbitrary user data to irq callback
Zephyr UART drivers offer very low-level functionality. Oftentimes,
it would be useful to provide higher-level wrappers around UART
device which would offer additional functionality. However, UART
driver irq callback routine receives just a pointer to (low-level)
UART device, and it's not possible to get to a wrapper structure
(without introducing expensive external mapping structures). This
is an indirect reason why the current UARt wrappers - uart_pipe,
console - are instantiated statically just for one underlying UART
device and cannot be reused for multiple devices.

Solve this by allowing to pass an arbitrary user data to irq
callback, set by new uart_irq_callback_user_data_set() function.
Existing uart_irq_callback_set() keeps setting a callback which
will receive pointer to the device.

While public API maintains compatibility, drivers themselves need
to be updated to support arbitrary user data storage/passing (as
legacy uart_irq_callback_set() functionality is now implemented in
terms of it).

parameters. This works by adding a separate enum with Qav request type
to the ethernet_qav_param struct.

Additionally this approach makes it much easier to document it all since
we now have just a single request and documentation comments in the
ethernet_qav_param struct.

a10d178078 drivers/pinmux: stm32 fix ports_enable array definition
ports_enable array holds port clock information.
It is populated for all SoCs, but ports availability depends on
SoCs. The way it is defined today, location of the port in the
array depends on previous ports definition in SoC CMSIS files.
Though, port index is always the same irrespective of previous
ports availability in the SoC.
This will result in incoherency between port index and clock
information.
Fix this by setting a bogus value if port is not defined.
Return an error if bogus value is read.

1b6e5f6143 drivers: eth: gmac: Enable 802.1Qav support
This commit makes the driver enable HW Qav support for all available
priority queues.

Note that the hardware doesn't support setting the deltaBandwidth
parameter directly, but it is possible to do this by calculating it
from the negotiated link speed.

The default settings are set according to 802.1Qav 34.3.1, that says:

  The recommended default value of deltaBandwidth(N) for the highest
  numbered traffic class supported is 75%, and for any lower
  numbered traffic classes, the recommended default value is 0%.

The default/recommended values can be changed using the ethernet
management API (set_config) - which this commit also adds.

This patch changes the way the transmitter is handled in the UART
driver, so that it is activated only when there is something to send.
The current UART API does not allow to disable RX completely, since
the poll_in function description implies that UART must continuously
listen. To provide a way of disabling the entire UART and lowering the
current consumption, this patch adds the power management to the UART
driver. When instructed to enter any of the power saving states,
the driver will disable the UART, and it will enable the UART back
when it is switched again to the active state.

Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

This is basically reapplying commit 133a299b50 ("drivers: i2c: Kconfig:

101d493622 drivers: serial: nrf: Use nrfx GPIO HAL to properly handle pins from P1
The dependency on the GPIO driver was a bit artificial, since the UART
driver used the GPIO API functions only to configure the pins at its
initialization. This configuration will be done by using nrfx GPIO HAL
functions directly, just like in case when a shim is using
an nrfx driver underneath.

HAL functions can be fed with the absolute pin numbers, that are
currently used for Nordic SoCs in Kconfig and DT, and for the GPIO
driver an additional translation would be required, to extract
the port and its relative pin number.

UART driver has to be initialized at PRE_KERNEL_1 (because of the
console using it) and currently the GPIO driver is initialized
at POST_KERNEL stage, so calling its API function form the UART
initialization routine was incorrect.

Fixes issues caused in GPIO driver due to overlapping GPIOTE
channel use in nRF5 software PWM driver and in Bluetooth
controller for implementing PA/LNA feature.

The issue is solved by assigning the base and available
channel count for GPIOTE considering whether PWM and/or
PA/LNA feature is selected in the Kconfig.

Fixes #8815.

81cfdec3a9 i2c: stm32_v2: restructure interrupt handling
This patch restructures stm32_i2c_v2 drivers Interrupts:
- NACK failures trigger an I2C event interrupt, so move
handling of NACK failure from error isr to event isr.
- Extract logic of interrupt handling to static functions. Use
isr functions (event & error OR combined) to call these. This
reduces duplication between error isr and combined isr.
- Restructure the error interrupt handling, so that it has no effect
when no errors occured and thus can be called by combined isr.
- Change interrupt logic from if/else to pure ifs for each flag.
This reduces code paths and leads to one call of the isr handling
multiple interrupt conditions, if there's more than one I2C
interrupt flags set.
This is the way it's done e.g. in linux kernels (since 4.14)

ec6b6c9f0c eth: mcux: Add an option for randomized, but stable MAC address
The previous default, CONFIG_ETH_MCUX_0_RANDOM_MAC, result in a random
MAC address changed each reboot. As reboots happen quite often during
development, while Ethernet peers usually cache existing MAC addresses
in ARP cache, this led to situation when a board after reboot didn't
respond to pings or any other connection attempts for random amount of
time (upo to 10-20s). This was quite confusing and looked like some
problem in driver/hardware/connection/whatever.

Instead, introduce new option, CONFIG_ETH_MCUX_0_UNIQUE_MAC, to make
MAC address from MCU unique identification register. This results in
randomized/unique MAC address which is also stable over reboots and
avoids the situation described above.

  ...is selected by...

  config SPI_2_NRF_SPIS
  	bool
  	select SPI_SLAVE

  ...is in the choice...

  choice
  	bool
  	depends on SPI_2

  ...that depends on...

  config SPI_2
  	bool
  	depends on SPI_SLAVE

  (Defined at
  arch/x86/soc/intel_quark/quark_se/Kconfig.defconfig.series)

  ...that again depends on SPI_SLAVE

(This might not be a problem in practice, but it'd be difficult to
detect.)

I think the underlying issue is that SPI_2_NRF_SPIS 'select's SPI_SLAVE,
while SPI_2 'depends on' it.

Fix it by having SPI_2_NRF_SPIS 'depend on' SPI_SLAVE as well. This will
require SPI_SLAVE to be explicitly enabled before SPI_2_NRF_SPIS can be
enabled.

No configuration files in Zephyr itself seem to currently enable
SPI_2_NRF_SPIS (and it defaults to n), so no tweaks should be needed
there.

7688f49065 drivers: usb_dc_stm32: change all endpoints to bidirectional
The various STM32 reference manuals sometimes define the USB endpoints
as IN or OUT only and sometimes as bidirectional, even in the same
manual. This is likely because the OTG implementation has one set of
registers for the IN endpoints and one other set for OUT endpoints.
However at the end a given endpoint address can both transmit and
receive data.

This causes some confusion how to declare the endpoints in the device
tree, and depending on the SoC, they are either the same number of IN
and OUT endpoints declared, or they are declared as bidirectional. At
the end it doesn't really matter given how the driver uses those values:

    #define NUM_IN_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
                       CONFIG_USB_NUM_IN_ENDPOINTS)

    #define NUM_OUT_EP (CONFIG_USB_NUM_BIDIR_ENDPOINTS + \
                        CONFIG_USB_NUM_OUT_ENDPOINTS)

    #define NUM_BIDIR_EP NUM_OUT_EP

This patch therefore cleanup the driver, the DTS, and the DTS fixups to
only define the number of bidirectional endpoints.

In addition to the cleanup, that fixes a regression introduced by commit
52eacf16a2 ("driver: usb: add check for endpoint capabilities"), which
introduced a wrong check for SoC only defining the number of
bidirectional endpoints.

This is a rare but valid case when you request the controller to send
dummy bytes on your behalf (it saves memory as you don't need to provide
a valid buffer, just NULL and the numbers of dummy bytes as length).

Without it, user code can get stuck into interrupt loop.

10d54e2b22 boards: arm: argonkey: Properly set choice default
The choice symbol LSM6DSL_EXT0_LIS2MDL was given a 'default' in
Kboards/arm/96b_argonkey/Kconfig.defconfig, but 'default' has no effect
on choice symbols, triggering a warning from Kconfiglib.

Instead of adding a default to the choice symbol, change the default of
the 'choice' itself by giving it name and adding the default in
Kconfig.defconfig.

This requires that we remove the default on the "base" definition of the
'choice', due to some messiness related to the Zephyr-specific
prefer-later-defaults behavior (see the 'Zephyr-specific Kconfig
behavior for defaults' section in the Board Porting Guide). Choices were
overlooked when that patch was added to the C tools, meaning choices
still prefer earlier defaults. The crux is that Kconfig.defconfig files
are included last.

CAVS_ICTL_0_IRQ_PRI to CAVS_ICTL_3_IRQ_PRI and DW_ICTL_IRQ_PRI
are now defined in Kconfig. This addresses the issue #7811.

This was not throwing up any compilation error earlier as the IRQ
priorities are all hardwired in Xtensa and hence are unconfigurable.
They are dummy for Xtensa arch but may be applicable if used in some
other arch.

373a02126e drivers: serial: nrf: Fix interrupts enabling/disabling
This patch corrects the way the INTENSET and INTENCLR registers are
accessed. When these registers are written with a bitmask, specified
bits are set or cleared in the INTEN (interrupt enabling) register,
so there is no need to read the previous state of these registers
(when they are read, the current state of INTEN is returned).
For INTENSET this patch eliminates only one unnecessary read, but for
INTENCLR the change is crucial because in the previous version any
write to the register disabled all the enabled interrupts.

In case ethernet cable is unplugged, stm32 ethernet driver triggers
an error, driver initialization fails and fw crashes.
This could be enhanced as in case not cable is connected, HAL
returns a Time out, and will resume its initialization when
cable is plugged.
Treat HAL timeout in ethernet driver initialization as a
recoverable error and continues driver init when it happens.

Tested with sample/net/dhcpv4_client. Start board with cable
unplugged. Wait some time before plugging the cable. DHCP request
is correctly performed when cable is plugged.

The toplevel adc_seq_table is now copied onto the stack and
the stack copy used.

The contained entries array is now copied onto an allocation
drawn from the caller's resource pool, to prevent modification
of the buffer pointers.

The return value policy here is to oops the caller if bad memory
or objects are passed in, but return an error otherwise.

Based on an original patch by Leandro Pereira, rebased and the

8345e5ebf0 syscalls: remove policy from handler checks
The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:

* System call handlers that acquire resources in the handler
  have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
  to the caller instead of just killing the calling thread,
  even though the base API doesn't do these checks.

These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.

At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/

The macros now use the Z_ notation for private APIs.

39d63d316b clock_control: Add support for getting LPO frequency in mcux sim driver
The mcux sim clock control driver was originally designed to pass
through the clock subsystem value from dts to the mcux CLOCK_GetFreq()
function. This assumed that the values in
include/dt-bindings/clock/kinetis_sim.h matched the enumeration in
fsl_clock.h, which is true for the coresys, platform, and bus clocks.
However, the low-power oscillator (LPO) clock has a different values in
k64 vs. kw2xd, therefore we must update the clock_control driver to
parse the value from dts and convert it to the fsl_clock.h enumeration.

TimerHandle->Init.Period is used to initialize TIMx ARR register. The
timer will count from 0 up to ARR including, thus it will tick
(ARR + 1) timers per period. As the "period_cycles" variable holds the
number of desired ticks, the ARR register is computed as

ARR = period_cycles - 1

Update the code to reflect this relationship. Otherwise the timer will
count one more tick for each period, leading to a wrong PWM frequency.

b0db28b512 drivers: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for driver files.
Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.

In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

547ed9b563 kconfig: Make 'source' non-globbing and use 'gsource'
Until now, Zephyr has used a patched Kconfiglib that turns 'source' into
a globbing source (by replacing 'source' with 'gsource' at the token
level). There's two problems with this:

  - The patch needs to be maintained separately

  - Misspelled filenames are silently ignored, as they look like glob
    patterns that don't match anything

Fix it as follows:

  1. Replace all 'source' statements that use wildcards with 'gsource'

  2. Remove the custom Kconfiglib patch so that 'source' no longer globs

The sed pattern '/source.*[*?]/s/source/gsource/' was run over all
Kconfig* files to do the replacement.

source's that use environment variables that might contain glob patterns
were manually changed to gsource.

Building the docs in doc/ is a good test, as doc/Makefile deliberately
sets the environment variables to glob up as many Kconfig files as
possible.

none of the existing pinmux drivers do any kind of input validation
for the pin/op parameters, which has been shown to allow the caller
to access unauthorized memory, up to and including disabling the

This requires a proper specification for the pinmux subsystem and

57e80e5345 ext: mcux: Reorganize imported drivers into soc family subfolders
We have been combining imported mcux drivers into a flattened directory
structure to maximize driver reuse, but the introduction of additional
nxp soc families (lpc and imx) to zephyr has introduced driver naming
conflicts. This caused us to rename and modify imported files, such as
fsl_gpio.c/h, to make them unique across all three nxp soc families.
This makes updating the the mcux drivers complicated, especially for the
lpc family.

Reoganize the mcux drivers into soc family subfolders, so we can just
copy all the drivers from an mcux distribution (which is done on an
soc-basis) into the appropriate soc family folder. Undo all of the
naming changes that occurred when lpc and imx drivers were originally
imported. Undo the accidental squashing of the kinetis watchdog and dcdc
drivers that occurred when the imx drivers were introduced.

The drawback to this approach is that we have duplicate files when the
same hw ip modules exist in multiple soc families, however there are
only few cases where this occurs, such as fsl_lpuart and fsl_trng.

51a2090780 newlib: Fix compiler warning when using Newlib
- There is a mismatch when interfacing with external code where a
  uint32_t is defined as a parameter and internal Zephyr code attempts
  to use u32_t. If NewLib is used, the typedef for u32_t is
  'unsigned int' which is not a portable match to uint32_t as
  'unsigned int' is not a common size across architectures so gcc will
  output a warning.
- The mcux flash code calls NXP supplied functions that expect a
  uint32_t.
- openthread.c ot_state_changed_handler has a uint32_t flag as a
  parameter.

93689bdc80 kconfig: Remove no-op selects of choice symbols
Selecting a choice symbol is always a no-op, and the latest version of
Kconfiglib prints a warning. This commit removes all selects of choice
symbols, which might make the Kconfig files a bit clearer and gets rid
of the warnings.

This is just a dumb removal. I did not try to guess the intent of each
select.

Fixes #6849

cfdaa1dcaf drivers: usb: nrf5: Fix cdc_acm OUT endpoint read size issue
Problem:
cdc_acm sample outputs junk characters to the console when any key
is pressed. It is supposed to echo the same character as the input.

Analysis:
nRF52840 USB driver always reads 64 bytes from the USB peripheral's
local buffer irrespective of the data length. Even when 1 byte
is sent by the host, the usb driver receives as 64 bytes.

Since the maximum packet size value had been used when setting up
the EasyDMA's MAXCNT register for OUT transactions, DMA transffered
the entire 64 bytes of it's local buffer into the data RAM
irrespective of the OUT data length, containing garbage at the end
of useful payload. For some applications like hci_usb the extra
bytes were being ignored. But for cdc_acm, the entire 64 bytes
is getting echoed back displaying garbled characters on the terminal.

Fix:
For OUT endpoints, the amount of data received by USBD to its local
buffer should be read using SIZE.EPOUT[x] registers in the case of
BULK and INTERRUPT endpoints and SIZE.ISOOUT register for ISOOUT
endpoint. This value should be set to the EasyDMA maxcnt register
to DMA into RAM buffer. Fix this issue for Bulk, Interrupt and
ISOOUT endpoints.

* Add USB device controller driver for nRF52840 SoC.
* Supports only Bulk and Interrupt endpoints for now.
* ISO endpoint support is WIP.

What's tested:
* BTUSB - LE Scanning and connection.

Known issues in btusb tests:
 * Observed momentary delays during LE scanning. This is possibly
due to hci_usb's way of calling the usb_write().

 * Sometimes, when LE scan stop command is issued, response is not
sent and as a result USB stops functioning. This is also related
to the way btusb is handling the write(). For some reason, the
btusb class handler seems to issue another data packet write before
the USB control transaction is complete.

Miscellaneous:
* Lots of TODO items to discuss and fix.

This driver uses a bit-banging based technique of generating a signal
for the WS2812B LED strip. Since bit-banging is very timing sensitive,
where each CPU cycle counts, the driver uses inline assembly to
perform the most critical operataions. This initial version of the
driver only supports a Cortex-M0 implementation, and can e.g. be used
with the ZIP Halo LED strip for the BBC microbit:

400dc79326 timer: cortex_m: Fix the discontinuous readings of the cycle counter.
On a stm32, When we use the k_busy_wait function to wait a
delay (500us) just after an idle tickless period the delay could be
lower than the requested one. Consecutive readings of the cycle counter
made with the function k_cycle_get_32 juste after tickeless period
provides erroneous values (value jump) after some time (100 us).

To fix this issue we needs:

- Add the update of clock_accumulated_count value in the
_timer_idle_exit function.

- Treat the case in the get_elapsed_count function when the reload value
of the timer is set to a remaining value to wait until end of tick (see
_timer_idle_exit) . In this case the time elapsed until the systick
timer restart was not yet added to clock_accumulated_count. To retrieve
a correct cycle count we must therefore consider the number of cycle
since current tick period start and not only the cycle number since the
timer restart.

564f59060c kernel: SMP timer integration
In SMP, the system timer is used for timeslicing on auxiliary CPUs,
but the base system timekeeping via _nano_sys_clock_tick_announce() is
still done on CPU0 only (because the framework isn't prepared for
asynchronous notification yet).  Skip processing on CPU1+.

Also, due to a hardware interaction* that is difficult to work around,
timer initialization on the auxiliary CPUs is done at the very end of
the CPU bringup, just before the swap into the scheduler.  A
smp_timer_init() API has been added for this purpose.

* On ESP-32, enabling the timer seems to result in a near-synchronous
  interrupt being delivered despite my best attempts to keep it
  masked, then blowing things up because the CPU record isn't set up
  to handle it yet.

b7623a85b0 sensors: Redefine SENSOR_CHAN_HUMIDITY in percents, not milli-percents.
Based on the discussion in #5693, the reason why humidity was defined
in milli-percent was likely following Linux which defines it as such
in its sensor subsystem:
http://elixir.free-electrons.com/linux/latest/source/Documentation/ABI/testing/sysfs-bus-iio#L263

However, Linux defines temperature in milli-degrees either, but
Zephyr uses degrees (similarly for most other quantities). Typical
sensor resolution/precision for humidity is also on the order of 1%.

One of the existing drivers, th02.c, already returned values in
percents, and few apps showed it without conversion and/or units,
leading to confusing output to user like "54500".

So, switching units to percents, and update all the drivers and
sample apps.

For few drivers, there was also optimized conversion arithmetics
to avoid u64_t operations. (There're probably more places to
optimize it, and temperature conversion could use such optimization
too, but that's left for another patch.)

b23d599682 usb: stm32: Introduce transfer method
Transfer is an important concept of USB specification.
During a transfer, several packets can be transmitted.
Today the usb API only provides ep_read and ep_write
functions but the transfer concept is missing.

This is typically ok for basic drivers which don't have
to take care of how data is transfered/splitted.
However there are some drivers like CDC EEM, in which
transfer concept is important for packet management.

Moreover, current ep-write and ep_read method have a
different implementation in usb_dc_dw and usb_dc_stm32
device drivers. For example usb_dc_dw supports only
1-data-packet transfers due to its implementation.
This can increase latency and reduce performance.

I think this is something we need to fix/improve by
implementing better transfer management.

This patch introduces usb_dc_ ep_transfer method which
can be used to configure IN/OUT transfers. This allows
to configure and request different transfer sizes and
should prevent usage of the current stm32 temporary
buffer.

This method has asynchronous and synchronous mode.
Synchronous mode waits for transfer completion before
returning. Asynchronouse mode (irq safe) configures
the transfer and returns immediately, the provided
callback will be then called on transfer completion.

This also update ep_write and ep_read stm32 implementation
to use this new method but keep their behavior unchanged
for legacy reasons.

Note that for now this method is local to stm32 device
driver, however the goal would be to expose this function
as a new USB device driver API method so that class
drivers use it. This will request same implementation in
the usb_dc_dw_driver.

8ded57d3a2 drivers/ieee802154: Add support for Sub-GHz TI CC1200 chip
CC1200 is a sub-ghz chip supporting 6 ISM & SRD bands: 169, 433, 470,
868, 915 and 920 MHz, with features dedicated to IEEE 802.15.4(g).

Current driver enables CC1200 against actual IEEE 802.15.4 Soft-MAC. 'g'
version support in the Soft-MAC will follow later.

The chip itself is closer to a bare metal radio modem than to a usual
15.4 chip: up to the user to provide the right RF settings for the
carrier band. Such settings can be generaten through TI's SmartRF tool.

Hopefully, for channel selection, this driver will be clever enough to
compute the proper register change without any special input from the
user. This will work for all the bands supported by the chip.

SPI_MODE_GET() returns a bitfield. It is thus wrong to test if a bit is

instead.

This can be tested by setting the SPI in mode 3 (CPOL + CPHA). Currently
both tests will fail and the result is a SPI configured in mode 0. This
was confirmed using an oscilloscope. Applying the patch fixes the
polarity.

In ARC's SecureShield, a new secure mode (currently only em) is added.
The secure/normal mode is orthogonal to kernel/user mode. The
differences between secure mode and normal mode are following:

* different irq stack frame. so need to change the definition of
  _irq_stack_frame, assembly code.

* new aux regs, e.g, secure status(SEC_STAT), secure vector base
  (VECT_BASE_S)

* interrupts and exceptions, secure mode has its own vector base;
  interrupt can be configured as secure or normal through the
  interrupt priority aux reg.

* secure timers. Two secure timers (secure timer 0 and timer 1) are
  added.Here, for simplicity and backwards compatibility original
  internal timers (timer 0 and timer1) are used as sys clock of zephyr

* on reset, the processor is in secure mode and secure vector base is
  used.

Note: the mix of secure and normal mode is not supported, i.e. it's
assumed that the processor is always in secure mode.

eb83cda770 usb: dc_dw: Improve TX perf and reliability
During large USB transfer it's pretty common to call ep_write whereas
the previous TX transfer is not achieved and so the TX FIFO space is
not available. Sleeping 20ms in this case introduce a relatively high
latency and reduce the throughput.

This can be observed when pinging the board with CDC-ECM net class.
ping reply is split into 2 USB TX transfer, the second one is only
triggered after 20ms, making ping latency > 20ms.

To fix this, just continuously read the FIFO availabilty and fire TX
as soon as possible.

12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make

9bb07ff69a jailhouse: add support for x2APIC mode for all LOAPIC accesses
Besides the fact that we did not have that for the current supported
boards, that makes sense for this new, virtualized mode, that is meant
to be run on top of full-fledged x86 64 CPUs.

By having xAPIC mode access only, Jailhouse has to intercept those MMIO
reads and writes, in order to examine what they do and arbitrate if it's
safe or not (e.g. not all values are accepted to ICR register). This
means that we can't run away from having a VM-exit event for each and
every access to APIC memory region and this impacts the latency the
guest OS observes over bare metal a lot.

When in x2APIC mode, Jailhouse does not require VM-exits for MSR
accesses other that writes to the ICR register, so the latency the guest
observes is reduced to almost zero.

Here are some outputs of the the command line

  $ sudo ./tools/jailhouse cell stats tiny-demo

on a Jailhouse's root cell console, for one of the Zephyr demos using
LOAPIC timers, left for a couple of seconds:

See that under x2APIC mode on both Jailhouse/root-cell and guest, the
interruptions from the hypervisor are minimal. That is not the case when
Jailhouse is on xAPIC mode, though. Note also that, as a plus, x2APIC
accesses on the guest will map to xAPIC MMIO on the hypervisor just
fine.

97a8716a4f x86: Jailhouse port, tested for UART (# 0, polling) and LOAPIC timer
This is an introductory port for Zephyr to be run as a Jailhouse
hypervisor[1]'s "inmate cell", on x86 64-bit CPUs (running on 32-bit
mode). This was tested with their "tiny-demo" inmate demo cell
configuration, which takes one of the CPUs of the QEMU-VM root cell
config, along with some RAM and serial controller access (it will even
do nice things like reserving some L3 cache for it via Intel CAT) and
Zephyr samples:

   - hello_world
   - philosophers
   - synchronization

The final binary receives an additional boot sequence preamble that
conforms to Jailhouse's expectations (starts at 0x0 in real mode). It
will put the processor in 32-bit protected mode and then proceed to
Zephyr's __start function.

Testing it is just a matter of:
  $ mmake -C samples/<sample_dir> BOARD=x86_jailhouse JAILHOUSE_QEMU_IMG_FILE=<path_to_image.qcow2> run
  $ sudo insmod <path to jailhouse.ko>
  $ sudo jailhouse enable <path to configs/qemu-x86.cell>
  $ sudo jailhouse cell create <path to configs/tiny-demo.cell>
  $ sudo mount -t 9p -o trans/virtio host /mnt
  $ sudo jailhouse cell load tiny-demo /mnt/zephyr.bin
  $ sudo jailhouse cell start tiny-demo
  $ sudo jailhouse cell destroy tiny-demo
  $ sudo jailhouse disable
  $ sudo rmmod jailhouse

For the hello_world demo case, one should then get QEMU's serial port
output similar to:

"""
Created cell "tiny-demo"
Page pool usage after cell creation: mem 275/1480, remap 65607/131072
Cell "tiny-demo" can be loaded
CPU 3 received SIPI, vector 100
Started cell "tiny-demo"
***** BOOTING ZEPHYR OS v1.9.0 - BUILD: Sep 12 2017 20:03:22 *****
Hello World! x86
"""

Note that the Jailhouse's root cell *has to be started in xAPIC
mode* (kernel command line argument 'nox2apic') in order for this to
work. x2APIC support and its reasoning will come on a separate commit.

As a reminder, the make run target introduced for x86_jailhouse board
involves a root cell image with Jailhouse in it, to be launched and then
partitioned (with >= 2 64-bit CPUs in it).

Inmate cell configs with no JAILHOUSE_CELL_PASSIVE_COMMREG flag
set (e.g. apic-demo one) would need extra code in Zephyr to deal with
cell shutdown command responses from the hypervisor.

You may want to fine tune CONFIG_SYS_CLOCK_HW_CYCLES_PER_SEC for your
specific CPU—there is no detection from Zephyr with regard to that.

Other config differences from pristine QEMU defaults worth of mention
are:

   - there is no HPET when running as Jailhouse guest. We use the LOAPIC
     timer, instead
   - there is no PIC_DISABLE, because there is no 8259A PIC when running
     as a Jailhouse guest
   - XIP makes no sense also when running as Jailhouse guest, and both
     PHYS_RAM_ADDR/PHYS_LOAD_ADD are set to zero, what tiny-demo cell
     config is set to

This opens up new possibilities for Zephyr, so that usages beyond just
MCUs come to the table. I see special demand coming from
functional-safety related use cases on industry, automotive, etc.

eebb17ca52 usb_dc_dw: Correctness: use bytewise I/O in FIFO fill
The Designware FIFO is filled in units of 32 bit words, but the buffer
we are passed is not guaranteed to be a multiple of 4 bytes long, nor
aligned on a 4-byte boundary.  So in theory we are reading 0-3 bytes
of unused garbage from the end of the array.

That's currently benign on supported platforms with this hardware,
which all support misaligned reads.  But not all do.  And the incoming
arrival of memory protection opens the possibility that those extra
bytes would cross a protection boundary and cause a crash or security
bug.

Do this right.

(Note that this is fixed to little endian byte order.  The Designware
databook is frustratingly silent on the endianness it expects, but
existing hardware I can see is definitely LE and I see a few spots in
the Linux dwc2 driver that likewise assume LE).

f591e58211 usb_dc_dw: Correctly assign endpoint FIFOs
The designware hardware in dedicated FIFO mode (which is all we
support right now for lack of shared-FIFO hardware) has one hardware
FIFO per IN (i.e. transmit) endpoint.  But it doesn't assign them on
its own, it's the drivers responsibility to populate the TxFNum field
of the DIEPCTL registers with integer indices corresponding to the
desired FIFO.

We weren't doing that, which meant that all IN endpoints were sharing
the same FIFO zero which is supposed to be dedicated to EP0 control
transfers.  The net effect is that sometimes outbound transfers would
be corrupted, showing data from the wrong endpoint.  More often that
not this would leak from control transfers over to the
higher-bandwidth bulk endpoints of the application, but occasionally
you'd see a control transfer itself get borked and the USB device
would glitch.

Get this right and set the FIFOs properly.

669327137b drivers: led_strip: add WS2812-ish driver
The WS2812 LED driver IC has a one-wire interface which encodes bit
values as pulse widths.

The ICs themselves are basically shift registers. Roughly speaking, a
"short" pulse shifts in a zero bit, a "long" pulse shifts in a one
bit, and an inter-pulse gap exceeding a reset time threshold causes a
pixel to latch the shifted-in color values. Each chip has an output
pin for daisy chaining. Refer to the chip datsheets and comments in
Kconfig.ws2812 for more details.

To meet timing without hogging the core, this driver generates pulses
using SPI. To work, this requires the MOSI line to stay low between
SPI frames, and for inter-frame delays to be less than the reset pulse
time.

There are other ways do it (PWM + DMA on some SoCs, GPIO bit-banging
if no other tasks need the core), but this is a reasonably
general-purpose implementation.

b7eaeb9f0a cleanup: Use quote include instead of system include
When the header file is located in the same directory as the source
file it is better to use a relative quote-include, e.g.

than a system include like

Avoiding the use of system includes in these cases is beneficial
because;

* The source code will be easier to build because there will be fewer
system include paths.

* It is easier for a user to determine where a quote-include header
  file is located than where a system include is located.

* You are less likely to encounter aliasing issues if the list of
  system include paths is minimized.

f00f58517b doc: replace UTF-8 chars
Some our Zephyr tools don't like seeing UTF-8 characters, as reported in
issue #4131) so a quick scan and replace for UTF-8 characters in .rst,
.h, and Kconfig files using "file --mime-encoding" (excluding the /ext
folders) finds these files to tweak.

4fea6dfe76 flash: stm32: clean up L4/F4 internal API
This is a prep work commit for adding flash page layout support.

The internal flash APIs for STM32 on L4 and F4 are a bit
inconsistent. Some routines take a pointer to the private data, others
don't. Those that do take it as a last argument instead of a
first. Additionally, some APIs are declared in flash_stm32.h that
aren't ever used by the family-specific files.

Clean this up by making everything take a struct device*, and marking
routines static in the common driver code when possible.

bd5c2c07b3 Bluetooth: hci: spi: abstract out legacy SPI API
Some targets (e.g. STM32-based boards) only have SPI drivers using the
new API. To support both these and existing, legacy SPI drivers in the
SPI HCI driver, abstract out the SPI API into shim routines.

There are no behavioral differences due to this patch. The next patch
will add support for the new API.

4f67a6c76d cc3200: Remove TI cc3200 SOC and LaunchXL board support
Per ZEP-1958, Phase 2 of adding CC3220sf LaunchXL support,
was to "deprecate the CC3200 launchxl support in Zephyr
(redundant to the CC3220)."

Effectively, the CC3220 SOC replaces the CC3200.

This patch removes the following:
* the imported CC3200 SDK
* CC3200 SOC, board, DTS files.
* adjusts other files where cc3200 was mentioned.

Also, it fixes explicit references to CC3200 in generic
CC32xx driver files.

db6ff4da60 drivers: random: Add ESP32 random number generator driver
The random number generator from ESP32 uses noise from Wi-Fi and
Bluetooth radios.  If these are off, a pseudo-random number is
generated instead; this is currently the case, but even though it's a
black box, it's arguably better than returning a timestamp as a
pseudo-random number generator.

According to the ESP32 Technical Reference manual, the RNG passed the
Dieharder Random Number Test suite (version 3.31.1)[1], but nothing has
been said about the quality of the PRNG.

The RNG register is read directly; no effort is made to use its
contents to feed an entropy pool in a way that's similar to /dev/random
on POSIX systems, as no such subsystem exists on Zephyr at the moment.

197e6e2ba3 Kconfig: Move BLUETOOTH_HCI_RESERVE into subsys/bluetooth/host
There are two kinds of HCI implementations. Bluetooth drivers in
 drivers/bluetooth that implement HCI by using a wired serial
 transport layer to talk to an external controller chip. And a
 bluetooth controller in subsys/bluetooth/controller that directly
 talks to an internal on-chip controller node.

Currently, when the the subsys/bluetooth/controller is used there
still exists exposed to the user a bluetooth driver configuration
menu, even though no external bluetooth driver is in use. This is due
to a dependency on certain configs in driver/bluetooth that are needed
even though no external controller is used.

This patch moves one of these configs, BLUETOOTH_HCI_RESERVE, from
drivers/bluetooth/hci/Kconfig to subsys/bluetooth/host/Kconfig such
that eventually we can omit the entire Bluetooth driver menu option.

This re-organization does not change when the config can be enabled.

f3b18bc2e9 drivers: spi: stm32: fix transmit/receive procedure
The transmit and receive procedure used in the STM32 SPI driver is not
correct.

On STM32F4, this is causing OVR errors (per the logged error mask) and
transmission of undesired 0x00 bytes (verified with a logic analyzer).

The root cause is that the receive register is not read (via DR, when
RXNE is set) each time the transmit register is written (also via DR,
when TXE is set). This clearly causes OVR errors when there is no
FIFO, as the receive register needs to be read each time a frame is
transceived, or the IP block has no way of knowing that the
overwritten data were not important.

Adapt the I/O procedure so that every DR write is matched by a DR
read, blocking until the relevant flags are set if necessary.

This behavior is suboptimal for targets such as STM32L4, where there
is a SPI FIFO. However, SPI I/O is broken on those targets, and this
patch fixes them as well. Further optimizations for targets with FIFOs
is left to future work.

- the "asynchronous completion + polled I/O" combination is not

7b0f0f801c drivers: spi: stm32: fix hardware NSS management
The LL_SPI_NSS_* macros used in spi_stm32_configure() when
hardware-based NSS management is requested are incorrect; fix them.

In master mode, this seems like a copy/paste error. The slave mode
case is likely due to following incorrect documentation in the ST LL
headers.

Note that in my testing on STM32F4, NSS appears to be open drain when
managed by hardware, making that configuration harder to test (and
probably less useful).

Details for the curious:

    The ST LL headers (for example stm32f4xx_ll_spi.h) claim
    LL_SPI_NSS_HARD_INPUT is to be used only in master mode, and
    LL_SPI_NSS_HARD_OUTPUT is to be used in slave mode.

    The opposite is true: when NSS is not handled by software, the SPI
    peripheral is responsible for driving NSS as an output, and the
    slave peripheral is responsible for reading it as an input.

    This is an error in the LL header files; the reference manuals and
    the other LL code make this clear.

    - The ST reference manuals specify that LL_SPI_HARD_OUTPUT (which
      corresponds to SSM unset, SSOE set) is a master-only
      configuration.  For example, STM32 RM0368 says:

        "NSS output enabled (SSM = 0, SSOE = 1)

        This configuration is used only when the device operates in
        master mode."

    - LL_SPI_HARD_INPUT (SSM unset, SSOE unset) is either a master or
      a slave configuration; in the slave case (which is what we're
      interested in here), it corresponds to the "usual" NSS
      input. RM0368, again:

        "NSS output disabled (SSM = 0, SSOE = 0)

        This configuration allows multimaster capability for devices
        operating in master mode. For devices set as slave, the NSS
        pin acts as a classical NSS input: the slave is selected when
        NSS is low and deselected when NSS high."

      The LL_SPI_StructInit() implementations similarly combine
      LL_SPI_MODE_SLAVE with LL_SPI_NSS_HARD_INPUT.

Now that struct spi_context supports passing errors from
interrupt-driven I/O handlers to waiting threads, we can enable error
interrupts and propagate errors to spi_transceive() callers.

To make it easier for users to debug SPI-related issues, log any error
bits set in SR when failures occur.

A subsequent patch will add error checking to polled mode as well, but
other cleanups and fixes will go in first to make this easier.

Note that this breaks the spi_loopback test on some targets, but it's
not a regression, as it wasn't working properly anyway. Subsequent

6c717095b8 drivers: spi: report synchronous completion status
The SPI API allows waiters to block until SPI I/O has completed. The
asynchronous subset of the API allows waiters to learn a status value
for the result of the I/O. However, the synchronous API does not allow
this.

Due to this limitation, synchronous API users cannot learn when
interrupt-driven I/O fails, which precludes proper error handling.

Resolve this limitation by adding a sync_status field to struct
spi_context, and using it to return operation results to the waiter.

Since there is only one status field, reduce the maximum number of
supported waiters from UINT_MAX to 1. This is not a problem for
current users, which all wait with the entire context locked.

65a9d2a94a kernel: make K_.*_INITIALIZER private to kernel
Upcoming memory protection features will be placing some additional
constraints on kernel objects:

- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.

Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.

It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.

There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.

k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.

cced7fd47a api/spi: Change transceive functions signature
Instead of NULL terminated buffer arrays, let's add a parameter for each

It adds a little bit more complexity in driver's side (spi_context.h)
but not on user side (bufer one has to take care of providing the NULL
pointer at the end of the array, now he requires to give the count).

This will saves a significant amount of bytes in more complex setup than

This will inhibate the gpio cs delay, if any. This might be useful when
doing consecutive calls on one slave without releasing the CS.

SPI_LOCK_ON is to be used with caution as it will keep the SPI device
locked for the current config being used after each transaction. This
can be necessary if one needs to do consecutive calls on a slave without

a9183cd518 flash: Rework and add flash device support for STM32L4x SoCs
The STM32L4x SoCs embeds a slightly different embedded flash controller
from the STM32F4x SoCs.

This particular controller has the following properties :
 - Up to 2 512KiB banks divided in 2KiB pages
 - Flash can be accessed in any sizes
 - Flash must be written in 64bit aligned 64bit double-words

The drivers/flash/flash_stm32f4x.c is refactored into a new common
drivers/flash/flash_stm32.c and drivers/flash/flash_stm32l4x.c is
created with the STM32L4x specific functions.

To ease the refactoring and keep common functions, the STM32L4x flash
headers are slightly modified to match the hardware reference naming
and solve compilation issues.

0fdc9b5b12 drivers: serial: Clarify usage of TX/RX IRQ predicates.
uart_irq_tx_empty() function proved to be problematic: its semantics
was not documented properly, and many hardware uses terminology like
"TX register empty" to signify condition of TX register being ready
to accept another character (what in Zephyr is tested with
uart_irq_tx_ready()). To avoid confusion, uart_irq_tx_empty() was
renamed to uart_irq_tx_complete(), propagating to drivers/serial
device methods.

The semantics and usage model of all of uart_irq_rx_ready(),
uart_irq_tx_ready(), uart_irq_tx_complete() is now described in

Commit 58c8d15 ("clock control:stm32: provide STM32Cube LL based
driver") added PLL initialization which disables the PLL before
configuring it.

This works if the system clock source is not the PLL (which is the
usual case for Zephyr booting out of chip reset). However, if the
SYSCLK source *is* the PLL, this halts execution.

To support this use case, switch the SYSCLK source to the
always-present HSI before disabling the PLL.

1c4b09947f drivers: eth_dw: Port to new IP stack
The main difference to how the previous driver operates, is that this
version has zero-copy transmission.  The transmit DMA descriptor is
updated for every fragment that is transmitted from the driver.

Another difference in the transmission path is that this version won't
spin indefinitely while waiting for the DMA transfer to complete; an
arbitrary number of busy checks (20) will be performed, and then
the transmission thread will yield for as long as necessary to finish
the transfer.

These two changes should fix ZEP-472; since that issue was opened for
an older version of Zephyr with uIP, I did not bother going all the way
back to test.

This has been only tested with a Galileo board, using Shared IRQ.

The purpose of irq_update() is to cache value of UART IRQ status
register for devices which needs such caching. No other driver
performs any other side effects in this call. For STM32, clearing
TC (tx complete) bit was introduced in 8c079e91c9
which is otherwise titled as a conversion to STM32Cube HAL. Thus,
there does not seem to be specific reasons why this code was added.
On the other hand, it leads to behaviorial artifacts when dealing
with interrup-driven UART code (specific issue seen was delaying
of transmitting every other character).

25307d5331 net: net_pkt_append: Refactor to return length of data actually added
For stream-based protocols (TCP), adding less data than requested
("short write") is generally not a problem - the rest of data can
be sent in the next packet. So, make net_pkt_append() return length
of written data instead of just bool flag, which makes it closer
to the behavior of POSIX send()/write() calls.

There're many users of older net_pkt_append() in the codebase
however, so net_pkt_append_all() convenience function is added which
keeps returning a boolean flag. All current users were converted to
this function, except for two:

samples/net/http_server/src/ssl_utils.c
samples/net/mbedtls_sslclient/src/tcp.c

Both are related to TLS and implement mbedTLS "tx callback", which
follows POSIX short-write semantics. Both cases also had a code to
workaround previous boolean-only behavior of net_pkt_append() - after
calling it, they measured length of the actual data added (but only
in case of successful return of net_pkt_append(), so that didn't
really help). So, these 2 cases are already improved.

abf284e9fd Revert "serial: stm32: Give H/W a chance to set the TXE bit on transfer"
Don't busy-wait in uart_stm32_fifo_fill(), this routine is supposed
to be called on IRQ, and the waiting loop was shown to interfere
with interrupt-driven UART handling.

The original problem mentioned in the patch being reverted ("it is
possible to evaluate the TXE bit *before* H/W has had the
opportunity to detect that data is being processed") may still
exist and may require handling in a different way. The most obvious
way is to replace "while" loop with "if", because STM32 doesn't
have multi-level FIFO anyway. But I was dissuaded to include such a
change as part of this patch, so it's left for future analysis.

This reverts commit 49c2858d94.

89ffd44dfb kernel: tickless: Add tickless kernel support
Adds event based scheduling logic to the kernel. Updates
management of timeouts, timers, idling etc. based on
time tracked at events rather than periodic ticks. Provides
interfaces for timers to announce and get next timer expiry
based on kernel scheduling decisions involving time slicing
of threads, timeouts and idling. Uses wall time units instead
of ticks in all scheduling activities.

The implementation involves changes in the following areas

1. Management of time in wall units like ms/us instead of ticks
The existing implementation already had an option to configure
number of ticks in a second. The new implementation builds on
top of that feature and provides option to set the size of the
scheduling granurality to mili seconds or micro seconds. This
allows most of the current implementation to be reused. Due to
this re-use and co-existence with tick based kernel, the names
of variables may contain the word "tick". However, in the
tickless kernel implementation, it represents the currently
configured time unit, which would be be mili seconds or
micro seconds. The APIs that take time as a parameter are not
impacted and they continue to pass time in mili seconds.

2. Timers would not be programmed in periodic mode
generating ticks. Instead they would be programmed in one
shot mode to generate events at the time the kernel scheduler
needs to gain control for its scheduling activities like
timers, timeouts, time slicing, idling etc.

3. The scheduler provides interfaces that the timer drivers
use to announce elapsed time and get the next time the scheduler
needs a timer event. It is possible that the scheduler may not
need another timer event, in which case the system would wait
for a non-timer event to wake it up if it is idling.

4. New APIs are defined to be implemented by timer drivers. Also
they need to handler timer events differently. These changes
have been done in the HPET timer driver. In future other timers
that support tickles kernel should implement these APIs as well.
These APIs are to re-program the timer, update and announce
elapsed time.

5. Philosopher and timer_api applications have been enabled to
test tickless kernel. Separate configuration files are created
which define the necessary CONFIG flags. Run these apps using
following command
make pristine && make BOARD=qemu_x86 CONF_FILE=prj_tickless.conf qemu

bf964cdd4c net: Renaming net nbuf API to net pkt API
There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.

Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).

Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

Atmel SAM family GMAC Ethernet driver is implementing zero-copy
networking. As a result it has to reserve a defined amount of RX
data net buffers before bringing up the interface. Since net buffer
pool is initialized by the network stack and this driver was bringing
the interface up in its initialization function the driver initialization
was performed, as a workaround, after network stack initialization. It
is not a clean solution. This patch fixes this by bringing the
interface up in interface initialization function. The driver itself
can now be initialized before the network stack is.

e7391e3068 gpio: Add gpio_mmio32 driver to access basic 32-bit i/o registers
It is envisaged that this will be used by SoC or board code to make
available fixed purpose memory-mapped i/o registers to the rest of the
system which normally expects to use GPIO devices, e.g. for driving chip
select lines, LEDs or reading button states.

As such, the driver code doesn't provide a kconfig based configuration
mechanism, instead SoC/board code can hard-wire the devices it wants
with something simple like:

GPIO_MMIO32_INIT(misc_reg1, "MISC1", 0x12345678, 0xffffffffu)

Then, for example, if bit N of the register at 0x12345678 is wired up as
an SPI device chip select line, the SPI driver could be configured to
use pin N of the "MISC1" GPIO driver and not need any other board
specific code.

9b12803bf7 cc3200: Resolve DTS fixup.
As part of the transition to Device Tree, a temporary
HAS_DTS configuration variable, and a .fixup file per board
with symbol aliases were added.

This patch removes the cc32xx related fixup file
definitions, except for those used additionally outside
the cc32xx drivers.

Since cc32xx has DTS files, and since HAS_DTS will always be true,
it also removes the 'if !HAS_DTS' blocks from the cc32xx Kconfig
files.

Previously, cc3200_launchxl board was not able to show the

This patch moves the pinmux and UART driver initialization

380d24de1d drivers: Add support for BBC micro:bit LED display
Adds a simple driver to access the 5x5 LED display found on BBC
micro:bit boards. The display is so limited that no effort is done to
try to integrate with the existing console (which would likely make
the display unusable). Instead, dedicated mb_display_* APIs are added
that are specific to this display.

Rearming the riscv machine timer is done by first updating the
mtimecmp low value register. If the low value is updated with a
relatively small value, a timer interrupt can be generated while
updating the mtimecmp high value.

To avoid such a spurious interrupt to occur, disable the timer
interrupt while rearming the timer.

e1a6c7d472 drivers: slip: Allow specifying the MAC address from config file
The current state of affairs will not allow to set a MAC address and
thus will initialize a random MAC address.

However, when we are in a situation where we are trying to interface
Zephyr OS QEMU VMs with physical targets for testing, this is not
practical. We need to create a macvtap interface, on which we need to
set the MAC address of the Zephyr OS SLIP device so packets can be
routed.  There is no way to guess which random address is going to be
used, and there is no practical way to query it.

So this patch adds a CONFIG_SLIP_MAC_ADDR config
setting. slip_iface_init() is changed to take the code from
slip_get_mac() for initializing the MAC address (which should be
happening there anyway) and if CONFIG_SLIP_MAC_ADDR is set, it takes
that one -- otherwise goes to generate a random one.

1f2ee5c6bc sys_bitfield*(): use 'void *' instead of memaddr_t
Current users of sys_bitfield*() are bending over backwards to cast
what is most of the times a pointer into an integer.

Bitfields can be better described with an void *, so
uint{8,16,32,64}_t or any other container can be used. Most
sys_bitfield*() operations, by extension, can do the same. Note void *
has byte arithmetic, like char *.

This change will also make it implicit, for any future split of the
address space between virtual (what the SW is seeing) and physical
(what the HW is seeing) way clearer, as the functions dealing with
physical, non directly referentiable/mappeable addreses to use an
integer type, like mem_addr_t.

- include/arch/ARCH/*asm_inline*:

  - sys_bitfield*() all modified to take 'void *'

    Note 'void *' arihtmethic is byte based, which makes some things
    easier.

- include/sys_io.h:

  - introduces DEFINE_BITFIELD

203dec3b69 gpio: mcux: Revert to older GPIO device names as were used for Kinetis.
These are more consistent with naming used by other ports (uppercase,
short), and some existing software relies on them to be exactly those.
This change is a follow up to the discussion on the Zephyr mailing
list, calling to establish consistent naming conventions for Zephyr
devices, and is a small step in that direction.

e675352e10 eth/eth_mcux: Provide start and stop operations on the PHY driver.
Refactor the PHY state machine and add support for explicit start and
stop.

The stop implementation remains partial, the state machine will enter
a disabled state but will not actual attempt to power down the PHY.
This is deliberate, while implementing this it has become apparent
that issuing a PHY power down command is an effective way of bricking
frdm-k64f boards, hence explicit power down deliberately disabled
until the issue is properly understood.

This patch simplifies the handling of interrupts and reduces

Minor fixes:
 - use mutex for the PHY access control
 - remove unnecessary mcr20a_mask_irqb calls
 - do not read RX_FRM_LEN twice
 - increase timeout for sequence synchronization semaphore
   if the log level greater than 1
 - enable only the Sequence-end (SEQIRQ) interrupt
 - fix magic in NET_DEVICE_INIT
 - make the timeout values dependent on the log level

68c9d9779c x86: loapic_timer: use TSC for k_cycle_get_32()
The LOAPIC driver was doing this in a way susceptible to a very
nasty race condition: the CCR register could reset and be readable
before the associated interrupt could be delivered.

This resulted in a small window of time where CCR was reset, but
accumulated_cycle_count not updated, causing some calls to
k_cycle_get_32() to appear to jump backwards in time.

Just use the x86 TSC for these cycle timestamps. A divisor may be
provided in cases where the CPU clock speed is some multiple of
the bus speed. Modern x86 CPUs do not change their TSC rate even
when adjusting cpu frequency, so this should be a reliable timing
source.

to the kernel in _timer_idle_exit(). Additionally, the driver now
makes sure never to announce more idle ticks than the kernel asked
for, since the kernel does not handle negative deltas in its timeout
queues.

867e61cbf3 drivers gpio: Fix disabling of interrupts for QMSI shims
When a GPIO pin is configured, the shim driver will first read the
current values in the controller registers to keep the other pins from
changing their configuration. After that it sets the bits for the
corresponding pin accordingly.

When the flag to enable interrupts is passed to the function, the
corresponding bits are all set properly, but no changes are made if
interrupts are not requested. This makes it impossible to disable
interrupts for a given pin once they've been enabled.

Fix it by always resetting the interrupt enabled bit when they have not
been requested. Other values can be left untouched as they won't have
any effect.

58c8d15147 clock control:stm32: provide STM32Cube LL based driver
This new clock control driver aims at providing a lightweight
generic driver to the whole stm32 family.
Driver is based on LL Cube API and hence is for now available
only for STM32 supporting this API: stm32f3xx and stm32l4xx.
Other families should be supported soon.
Once globally supported, this unique driver will also help
reducing the impact of stm32 clock control heterogeneity in
other drivers.

This patch adds DTS support and related files for the NXP Kinetis
platform.  The DTS files contain the base definitions for the hardware
nodes on Kinetis platforms.  The YAML files provide the definitions of

The Kconfig changes were put in place to allow for the conversion of
existing drivers.  Once those drivers are modified, the Kconfig options
that are replaced by the DTS information will be removed.

bd3908b2a9 net: nbuf: Add timeout to net_buf getters
This commit changes the net_buf getter functions in nbuf.h
by adding a timeout parameter. These function prototypes
are changed to accept a timeout parameter.
	net_nbuf_get_rx()
	net_nbuf_get_tx()
	net_nbuf_get_data()
	net_nbuf_get_reserve_rx()
	net_nbuf_get_reserve_tx()
	net_nbuf_get_reserve_data()
	net_nbuf_copy()
	net_nbuf_copy_all()
	net_nbuf_push()
	net_nbuf_append()
	net_nbuf_write()
	net_nbuf_insert()

Following convinience functions have not been changed
	net_nbuf_append_u8
	net_nbuf_append_be16
	net_nbuf_append_be32
	net_nbuf_insert_u8
	net_nbuf_insert_be16
	net_nbuf_insert_be32
	net_nbuf_write_u8
	net_nbuf_write_be16
	net_nbuf_write_be32
so they call the base function using K_FOREVER. Use the
base function if you want to have a timeout when net_buf
is allocated.

e290006144 serial: Introduce new mcux lpuart shim driver
Adds a shim layer around the mcux lpuart driver to adapt it to the Zephyr
serial interface.

NXP has multiple uart hardware blocks that implement different features
and have different register maps. The k64 has a uart block called
'uart', while the kw41 has a uart block called 'lpuart' (low power
uart). The MCUXpresso SDK provides separate drivers for each type of
uart block but with similar software interfaces. As a result, there are
also separate shim drivers in Zephyr. There is a 1:1:1 relationship
between hardware block, mcux driver, and mcux shim driver.

Because we now have two mcux shim drivers for the uart interface, a new
naming convention is created:

	<interface>_mcux_<hw block>

Where <interface> is the name of the Zephyr interface, in this case
'uart'. This convention is not new.

<hw block> is the name of the NXP hardware block, in this case 'lpuart'.
This is the new part, and distinguishes different hardware blocks
for the same interface.

83ed3a29be net/ieee802154: Modify radio TX function signature
The cause for this change is TCP. Until now, the radio strategy driver
(ALOHA or CSMA) was providing the actual nbuf, and not the buffer
fragment, counting on the fact that the loop was using
net_buf_frag_del() which made so, iteration after iteration, buffer
framgent to be always buf->frags. The problem with this logic is loosing
the fragments that might be still referenced by TCP, in case the whole
buffer did not make it so TCP can retry later and so on.

Instead, TX now takes the nbuf and the actual frag to send. It could
have been working with just a pointer on the data, and the whole length
of the frame. But it has been avoided due to possible future devices,
that will be smarter and run CSMA directly in the hw, thus it will
require to access the whole buffer list through the nbuf.

Telnet is started as an application, as it requires the net stack to be

depending of course on which one is enabled.

Current behavior is very basic, as it does not handle any telnet
command (IAC). These will be silently ignored.

3587b97845 net: slip: Do not remove fragments when sending data
The rationale for removing fragments while sending them is to free the
memory they're using as soon as possible.  This worked fine because
most protocols implemented initially did not require any
retransmission, so the upper layers were never holding an extra
reference to the buffer (& their fragments).

This is not the case anymore, as the TCP layer holds a reference to
a buffer (& fragments) while confirmation from the peer has not been
received, allowing retransmission.

With this change, the fragments of a buffer are not removed when being
sent by the SLIP layer; however, the buffer is still deferenced when the
transmission is complete.  If nothing else holds a reference, all the
fragments are returned to their respective pools, like before.

1c21029237 drivers/ethernet: Update default GPIO pin for the ENC28J60 module
All sample applicatons in Zephyr, using the ENC28J60 driver, set
the ETH_ENC28J60_0_GPIO_PIN Kconfig variable to 19.
However, in the Kconfig.enc28j60 file this variable is set to 24.
That default value, 24, was used only during the first iterations
of this driver and never used again.

In this patch, we set the Kconfig variable to 19 and simplify
project configuration files by removing one line.

7890290e81 Bluetooth: Add HCI SPI driver
This driver acts as a pass-through, taking raw HCI data, converting
it to SPI comms and vice versa.  It works in the same way as the
existing H:4 and H:5 drivers, only it uses SPI instead of UART.

In this first release, the only BLE board which has been tested is
the X-NUCLEO-IDB05A1:

  http://www.st.com/en/ecosystems/x-nucleo-idb05a1.html

Although the current supported SPI format works like the one below,
it should be trivial to adapt it to support other chips with a
different format.

SANITY CHECK = 0x02
SPI WRITE    = 0x0A
SPI READ     = 0x0B

Tx Format:

   [HOST] {SPI WRITE}     0x00          0x00  0x00  0x00  {HCI MESSAGE ...}
   [CHIP] {SANITY CHECK}  {FLASH SIZE}  0x00  0x00  0x00  {0xFF * MESSAGE LEN}

Rx Format:

   {IRQ LINE GOES HIGH}

   [HOST] {SPI READ}  0x00          0x00  0x00             0x00  {0xFF * BYTES TO READ}
   [CHIP] 0x02        {FLASH SIZE}  0x00  {BYTES TO READ}  0x00  {HCI MESSAGE ...}

645f867444 Bluetooth: Take advantage of IS_ENABLED macro for BT_DBG
The new IS_ENABLED macro allows exposing conditionally enabled code
always to the compiler, even though it may not ultimately end up being
built. This is in particular useful for letting the compiler catch any
logging format string errors. Introduce a new BT_DBG_ENABLED macro
that c-files need to define before including <bluetooth/log.h> in
order to choose whether BT_DBG() logs are enabled or not.

When no Bluetooth logs are enabled the patch also modifies the log
macros to have the format strings checked with the help of the
__printf_like annotation and empty static inline functions.

c0a546ed33 drivers: QMSI AON counter: Simplify driver reentrancy code
With the use of the IS_ENABLED macro
(https://gerrit.zephyrproject.org/r/#/c/9882), the driver
reentrancy code is simplified:

The original const variable which used to serve the purpose of
making the build to compile out the reentrancy code when the
reentrancy configuration flag is not enabled is no longer
needed as the use of the IS_ENABLED macro achieves the same result.
Also the original 3 wrapper functions around semaphores API are
not necessary; instead, just use the semaphore API directly.

Remove the type field from the sensor value structure. All values will

This simplifies the interface, as apps will know what value type to
expect. Apps that prefer to use double values can optain them using the
sensor_value_to_double function.

The straddled_tick_on_idle_enter variable was a bool, which resolved in

occupied 4 bytes anyway with alignment.

The k64 pinmux driver was deprecated when the more generic mcux pinmux
driver was added, but it can actually just be removed because it is not
a public interface. Applications should be using the public pinmux API,
not the private k64 pinmux API. There was one case in the net samples
that used the private API which was cleaned up in a previous patch.

b7386c3a26 arm: nordic_nrf5: Cleanup Kconfig dependencies for timer and clocks
On the nRF5x platforms we need always need the NRF_RTC_TIMER and it
depends on the CLOCK_CONTROL_NRF5.  So enable all of these always.

Fixes issues if one tries to build nRF5x platforms w/o CONFIG_BLUETOOTH.

Remove aio disabling code before calling callback. If aio is

interrupt check API in the callback will get negative result.
If user wants to disable the aio, it can do this in callback
instead of this being done blindly before callback.

So far the use of k_sem meant that there was no major benefit of

mechanism. Instead of using k_sem, introduce a k_fifo and use that to
queue up incoming buffers. This way the RX buffer count can be
increased with measurable effects on throughput.

Enable arc to access the i2c controller on I/O fabric.

X86 cpu is only able to access the i2c controller on the I/O

arc to access both controllers. But, the existing code only
gives arc access to the controller in the sensor sub-system.

2. Use the already defined macros to choose interrupt numbers

f2c1b4bb02 drivers: bmi160: use direct GPIO trigger instead of IPM
Directly use AON GPIO trigger instead of IPM.

In the past, SW did not allow arc to receive AON GPIO interrupt.
So, interrupt from BMI160 was routed to x86 cpu. Then, x86 cpu
passed the event to arc through IPM. But, SW was updated and arc
is able to directly receive interrupt from AON GPIO now. So, IPM
is not needed any more. Let's remove IPM related code and use
GPIO as the default trigger source.

This change is on top of the bmi160 sample app change to not use
IPM.

ca0951d42d drivers: timer: Optimize RTC driver and prevent past events
The nRF RTC driver, which is used a system clock driver due to the lack
of SysTick hardware on the SoC, was using too much CPU time in its
_timer_idle_exit() implementation due to the use of 64-bit arithmetical
operations. This was causing the ISR wrapper to add excessive latency to
critical interrupts, causing BLE controller asserts.
This patch addresses the issue by using exclusively RTC ticks instead of
OS ticks, thus avoiding the necessity to convert during
_timer_idle_exit() calls, which are the most critical to interrupt
latency.

In addition the driver is now able to detect setting tick events in the
past due to it being interrupted by a higher priority context, and will
reschedule and trigger the ISR at the same time.

there are no more const members in net_buf the buffer array can be

This change implies that tests, samples and applications that require

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of

c3e08c8fea net: buf: Redesigned pool & buffer allocation API
Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".

This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:

	NET_BUF_POOL_DEFINE(pool_name, ...);

Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.

This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

a4e823eee0 pinmux: Introduce new ksdk pinmux driver
Kinetis SoCs contain one or more PORT modules to handle pin muxing and
pin configuration. Unlike the existing k64 pinmux driver, this driver
handles each PORT module individually and can be used for other Kinetis
SoCs.

This driver uses KSDK CMSIS register accesses to the PORT module rather
than the KSDK PORT driver (fsl_port.h), because the Zephyr pinmux
interface contains both set() and get() functions to access the pin
configuration. The KSDK PORT driver only contains a set() function
(which is a very thin static inline function to modify the PCR
register), therefore building a shim on top of it would result in a
strange mix of using the KSDK PORT driver for the set() and a direct
CMSIS register access for the get().

212f5f28ed drivers: spi_k64: Fix RX overflow
This patch fixes RX overflow error in the k64 SPI driver.

Jira: ZEP-1351
Jira: ZEP-1352

Several circumstances lead to an RX overflow:

The RFOF_RE (RX fifo overflow) must not be set as default.
The flag is only set when rx_buf is available. Also it must
be checked inside spi_k64_isr whether RFOF_RE has been set or not.

If the rx_buf is not available and the incoming data
should be ignored, then MCR_ROOE need to be set.
Since it is not possible to change the MCR register
during the transfer, RX fifo must be emptied
if rx_buf_len < tx_buf_len.

The driver also uses spi_data.xfer_len now,
the variable was already defined. Now, transfers are also
possible if tx_buf_len < rx_buf_len (e.g. read slave device register).
spi_k64_push_data has been adjusted accordingly.

The patch simplifies the handling of interrupts.
The interrupts are also switched off in the event of an error.

The patch also fixes a few coding style issues.

f2b7492269 ethernet: Add driver initialization priority to Kconfig
The default kernel init priority is too low. Make this
configurable and set the default priority so that the
ethernet driver is started just before the network stack.

This commit adds generic ethernet priority and changes
currently available ethernet drivers to use it.

7a11439020 net: ieee802154: Fix current stack to completely drop CRC handling
The 802.15.4 frame has a header and in the end after the payload a CRC.
Overall MTU is 127 bytes, but CRC is most likely going to be generated
by the device itself (offloading). Because the limitation of current
nbuf, it's not possible to keep this CRC in the buffer because it
require a user data size of 127 bytes but if we do so, IP stack will
fill in as much as it can as packet data, thus occupying the 2 last
bytes. This generates bugs. A perfect solution would be to generalize a
better handling of MTU and head or tail reserve data into nbuf, but
this will probably be solved in the future.
