805dca917a soc: same70: check for mismatch between chip and HAL CIDR
The revision A and B of the chip are very close, so most of the code
will work if the wrong revision is selected. To avoid that, check that
the selected HAL and the chip CIDR match. Otherwise emit a warning
in the logs.

dffd779ff3 boards: arm: unify Nucleo-64 boards connectors image
At the moment there are two images for Nucleo-64 STM32 family board
connectors (img/nucleo_xxxxxx_connectors.png).

The images have the same canvas size (800x619) but different file
size in bytes and different color coding.

The first one (192K, 8-bit colormap) is used for

  * nucleo_f070rb
  * nucleo_f091rc
  * nucleo_f103rb
  * nucleo_l053r8
  * nucleo_l073rz

The second one (464K, 8-bit/color RGBA) is used for

  * nucleo_f030r8
  * nucleo_f302r8
  * nucleo_f334r8

Applying simultaneous black/white threshold to the images and
comparing them with imagemagick tools shows that the images
have no significant difference. Therefore we can use
nucleo_l073rz_connectors.png for nucleo_f030r8, nucleo_f302r8
and nucleo_f334r8.

1e314df89a scripts/dts: globals: parse gpio-map properties for connector nodes
gpio-map is a property of "nexus node", defined in dts v0.3.
It allows to describe a pin connector so it can be referenced
through phandles and hence used in expansion device nodes like a
shield header (typically implemented through overlays).

This change implements gpio controller resolution through these maps.
Few assumptions were taken in order to simplify the implementation.
These assumptions bring some limitations to the use of gpio-map
but my understanding is that this should still allow to cover most
use cases.

Assumptions:
-gpio-size is the same for all gpio-controllers referenced in a map
-optional properties gpio-map-mask and gpio-map-pass-thru are
supposed to be omitted
The understanding of this last assumption is that flags provided in
the expansion device node will overwrite the connector flags.

In a latter stage, when need happen, these limitations can be
revisited to unlock fully fledged gpio-map usage.

74e320d859 api: dma: add api to retrieve runtime status
Some applications using DMA, such as UART RX, could
need to complete the current DMA transaction earlier than
predefined, based on other termination conditions,
like UART's IDLE interrupts.

In that case, the client needs to know how many data are
still left in DMA transfer buffer so that it can figure
out how many data has been transfered. However, the current
DMA API doesn't provide any information for the client
to learn the transfer buffer information.

And some other information, like whether DMA transfer is busy
or not, transfer direction, etc, could interest a client.

So, added a dma API function to retrieve the current DMA
runtime status.

And implemented the API for STM32F4's DMA while keeping
others unimplemented.

c0a7e4d778 Bluetooth: Mesh: Fix RPL storage timeout handling
The default values for the timeouts, as well as non-defaults in most
Mesh samples, use a higher value for the RPL than then generic mesh
storage timeout. This hasn't had any effect in practice since the code
only uses the RPL timeout if it is *smaller* than the generic one.

The original intention of the code was to use the RPL timeout,
regardless of what the generic one is, whenever the RPL is the only
thing that needs updating. Add some helper macros to track the various
groups of pending flags, and perform the appropriate checks to apply
the RPL timeout whenever it's smaller than the generic timeout, or if
there are no other items to store besides the RPL.

4462069d74 drivers: gpio: sam0: Add interrupt support
This adds interrupt support to the SAM0 GPIO driver.  This is heavily
inspired by @nzmichaelh work in #5715.  The primary difference
from that implementation is that here the External Interrupt
Controller (EIC) is separated out into an interrupt controller driver
that is less tightly coupled to the GPIO API.  Instead it implements
more of a conversion from the EIC's own odd multiplexing to a more
traditional port and pin mask IRQ-like callback.  Unfortunately,
through the EIC on the SAMD2x are relatively well behaved
in terms of pin to EIC line mappings, other chips that share the
peripheral interface are not.  So the EIC driver implements a
per-line lookup to the pin and port pair using definitions extracted
from the ASF headers.

The EIC driver still makes some assumptions about how it will be used:
mostly it assumes exactly one callback per port.  This should be fine
as the only intended user is the GPIO driver itself.

This has been tested with some simple programs and with
tests/drivers/gpio/gpio_basic_api on a SAMD21 breakout and an
adafruit_trinket_m0 board.

b2b21412ae net/connection: Removing cache feature
There were various flaws in it that motivated its removal:

- No hash collision handling mechanism. In case that would happen, the
behavior of the network connection would be unknown. This is the main
drawback
- The lookup is not that much more efficient than the default one. The
only difference of gain is in connection comparison (a u32t comparison
vs a full connection compare). But the list handling is the same. It's
made worse by the presence of a negatives match array which can be
easily filled in and becomes then fully usless, appart from consuming
CPU. As well as adding a new connection: it requires the whole cache
to be cleared which is unefficient.
- Not memory efficient, even compared to a proper hash table.
Two arrays instead of one etc...

All of this could be fixed by using a proper hash table, though it
remains to be seen if such object could fit in Zephyr core.

622f4abdf2 net/ip: Make struct net_addr holding uninon of ipv6/4 unconditionally
It will help to use IS_ENABLED in place of #ifdef in relevant place.

Only struct net_if uses this structure.
In case only IPv4 is used, it will bloat up this struct by 12 bytes.

There are few reasons why this is "ok" in this case:

- On limited rom/ram system it will be unlikely to find a lot of
network interfaces so it should not harm much to raise the size of
struct net_addr.
- If IPv4 is the only enabled IP version, it gains a good amount of
rom/ram to discard IPv6 support so it is fine to steal a bit of this
gain to bloat up a bit struct net_addr.

da3f7feaf8 soc: arm: nordic_nrf: unrevert provide custom busy_wait implementations
This reverts commit bd24b31139.

While the test case failure described in #14186 is associated with the
cycle-based busy-wait implementation, that test is fragile, and fails
less frequently once the incongruence between ticks-per-second and the
32 KiHz RTC clock are resolved.  It also assumes that the system clock
is more stable than the infrastructure underlying the the busy-wait
implementation, which is not necessarily true.

The gross inaccuracies in the standard busy-wait on Nordic described in
issue #11626 justify restoring the custom solution.

As this applies to all Nordic devices, move the setting to the top-level
Kconfig.defconfig.

c76dd1edb7 soc: arm: nordic_nrf: change default SYS_CLOCKS_PER_SEC
The default system clock on all Nordic devices is based on a 32 KiHz
(2^15 Hz) timer.  Scheduling ticks requires that deadlines be specified
with a timer counter that aligns to a system clock.  With the Zephyr
default 100 clocks-per-sec configuration this results in 100 ticks every
32700 ticks of the cycle timer.  This reveals two problems:

* The uptime clock misrepresents elapsed time because it runs 0.208%
  (68/32768) faster than the best available clock;

* Calculation of timer counter compare values often requires an integer
  division and multiply operation to produce a value that's a multiple
  of clock-ticks-per-second.

Integer division on the Cortex-M1 nRF51 is done in software with a
(value-dependent) algorithm with a non-constant runtime that can be
significant.  This can produce missed Bluetooth deadlines as discussed
in upstream #14577 and others.

By changing the default divisor to one that evenly divides the 2^15
clock rate the time interrupts are disabled to manage timers is
significantly reduced, as is the error between uptime and real time.  Do
this at the top level, moving SYS_CLOCK_HW_CYCLES_PER_SEC there as well
since the two parameters are related.

Note that the central_hr configuration described in upstream #13610 does
not distinguish latency due to timer management from other
irq_block/spinlock regions, and the maximum observed latency will still
exceed the nominal 10 us allowed maximum.  However this does occur
much less frequently than changing the timer deadline which can happen
multiple times per tick.
