e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py

e65f8ba1f2 kconfig: gpio: Remove lots of redundant GPIO dependencies
Most of these are from source'ing a file within an 'if GPIO', and then
adding another 'depends on GPIO' within it.

'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

e5ee8035c7 drivers: gpio: Fix mcux driver to init successfully with no irq
Some mcux gpio instances do not have dedicated interrupt vectors and
therefore conditionalize out the IRQ_CONNECT() and irq_enable() calls
during driver initialization. The driver initialization incorrectly
returned an error in this case, when really it just has nothing to do.
The driver can still be used without interrupts, and the gpio configure
function returns an error if an application tries otherwise.

Commit a68120de6d introduced a check on
the init return value to prevent applications from using drivers that
fail to initialize. This in turn caused zephyr/samples/basic/threads to
assert on the frdm_kl25z board. Fix this by modifying the mcux gpio
driver to return success when there is no interrupt to connect.

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.

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

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

(...and a bunch of other variations that e.g. swapped the order of the

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

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.

Though, port index is always the same irrespective of previous

information.

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.

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.

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.

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

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.

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.

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.

deprecated.

New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

Such API has been obsolete for a long time and no one is using it

- All non-sticky RW registers for the GPIO device.
- The MASK register (interrupt routing register).

Note: No need to sve/resume AON_GPIO registers as
they all are sticky registers.

The suspend/resume functionality is implemented in
the QMSI shim layer as a fast and temporary solution,
it will be removed and migrated to QMSI later.

c1e4bcf996 gpio: For ARC EM Starterkit, a 4-port GPIO implementation is being added
The file gpio_dw_registers.h already had the 4-port GPIO
registers defined, yet the gpio_dw.c implementation didn't
support it properly. There are 4 ports here, not 2, and only
PORTA can support interrupts and debounce.

On the em_starterkit board, for example, PORTA
has 3 bits for buttons: A, L and R. The other 3 ports should not
be used with interrupts & debounce.

I've re-worked this file to derive the port number from the
base address given. The lower 6 bits are divided by 12 to
derive the port number. From this, the registers EXT_PORTA,
EXT_PORTB, EXT_PORTC or EXT_PORTD can be read.

Also, for those ports that don't support interrupts,
set irq_num to 0, and that code will be avoided. I've verified
that I can access GPIO now correctly on the EM Starterkit. The
em_starterkit board support will be submitted soon but I'm
staging in this change first.

8df10d4584 kconfig: untangle ordering and dependencies
There are two major issues with the kconfig:

() Some of the config options have incorrect dependencies inside help
   under menuconfig. For example, CONFIG_GPIO depends on BOARD_GALILEO.

() Since the SoC and board specific kconfig files are parsed first,
   the help screen would say, for example, CONFIG_SPI is defined at
   arch/arm/soc/fsl_frdm_k64f/Kconfig. This is incorrect because
   the actual config is defined in drivers/spi/Kconfig.

These cause great confusion to users of menuconfig/xconfig.

To fix these, the SoC and board defaults are now to be parsed last.

Note that the position swapping of defaults in this patch is due to
the fact the the default parsed last will be used.

And, spi_test is broken due to the fact that it requires
CONFIG_SPI_INTEL_PORT_1, but never enables it anywhere. This is
bypassed for now.

3172fca3a0 drivers: qmsi: Fix gpio, i2c and wdt for D2000
This patch fixes the gpio, i2c and watchdog shim drivers so they set the
CLK_PERIPH_CLK bit during driver initialization. Differently from Quark
SE, the peripheral clock gate bit (CLK_PERIPH_CLK) is not enabled by
default in Quark D2000. We have to explicitly set this bit in order to
properly initialize the device.

This issue has been masked so far because the CLK_PERIPH_CLK bit is set
when UART NS16550 driver is enabled. The UART NS16550 driver is enabled
by default for Quark D2000 so gpio, i2c and watchdog sample apps were
working just fine. But if we disable the NS16550 driver, these samples
applications stop working.

The remaining shim drivers already set the CLK_PERIPH_CLK bit during
initialization so there is no need to fix them.

52b499fd1f arm: Freescale K64/FRDM-K64F Pinmux support
K64 pinmux support is created as a normal driver.

As opposed to the Galileo board, the pin configuration options are
defined by the MCU and are not board-specific.  Separate
platform/board-specific configuration code uses the pinmux driver for
the default pin settings. For FRDM-K64F, only the Arduino pins (22 of a
possible 160) are set up.

Some of the I/O pins routed to the Arduino header are also configured as
JTAG/SWD signals by default and are used by the OpenSDAv2 debug
interface.  Therefore, a PRESERVE_JTAG_IO_PINS config option was created
for the FRDM-K64 platform to prevent the default pin settings from
re-configuring these pins.

The K64 MCU separates pin configuration and control, implemented in the
pinmux driver, from GPIO.  This results in some cross referencing
between the K64 GPIO driver and the K64 pinmux driver due to the
dependencies of one on the other.

This pinmux driver also uses the expanded pinmux function/mode parameter
size to describe pin configuration options with bit fields for the K64,
including up to 8 pin functions, plus interrupt, pullup/down, drive
strength, open-drain and slew rate.

The following GCC warnings in the K64 pinmux driver are prevented when not
compiling with 'no-optimization' (-O0):

warning: 'gpio_dev' may be used uninitialized in this function
[-Wmaybe-uninitialized]
