Use 'select SERIAL', as a serial driver is supported by practically
all boards, and avoids using extra overlays in samples and tests.
The pattern of using select was introduced for SENSORS in df81fef944,
and the only 1-wire I2C sensor was converted in 465b7615a9.

The adxl372 device does not select the correct bus that it is on, which
causes undefined operation (usually a fault). This driver should not be
using Kconfig to determine which bus to use, that should be done by
dts, however this works as a quick fix in the interim until the driver
can be fixed properly.

Remove the Kconfig option for configuring the maximum value of the CAN-FD
Data Length Code in order to ensure standard compliance.
Allowing users to configure the max DLC allows the user to save a number of
bytes per CAN frame in RAM, but it also renders the Zephyr CAN-FD
implementation non-compliant with the CAN-FD standard.
There are no guarantees that a Zephyr CAN-FD node will not receive a CAN
frame with a DLC higher than the Kconfig limit, which opens up for all
sorts of bugs when trying to handle received CAN-FD frames.

There are several test cases that create fake ethernet devices and
expect the fake device to be the only ethernet device enabled. Some
tests handle this be explicitly disabling actual ethernet drivers,
but this doesn't scale well.
Change drivers/ethernet/Kconfig to utilze a menuconfig option that
wraps all the drivers. This allows us for those test cases that
don't want any actual ethernet drivers to disable them with a
simple CONFIG_ETH_DRIVER=n.
Note, the fake ethernet devices utilize CONFIG_ETH_INIT_PRIORITY so
we have it outside of the 'if ETH_DRIVER' block.

When dealing with pm action 'suspend', driver applies device pinctrl sleep
state.
Using PM_DEVICE modes should allow to save more current consumption, and
applying pinctrl sleep state is one of the gains, but sleep state not being
available on a device is not a sufficient reason to block PM transition
to lower power mode.
If this pin state is not provided for the device, warn but don't block
pm transition. This will save some time to users setting up this feature
for the first time. Warning will give the opportunity to users to fine
tune their setup in a later step.

Instead of relying on Kconfig, use dt inputs to configure LPTIM domain
clck (LSI/lSE).
Clock control dedicated APIs are used for configuration and get the
frequency of domain clock in use.
Constants macros used previously to store frequency and time base are
converted to static global variables.
Some code was set up specifically to keep compatibility with targets
that still use Kconfig to configure domain clock. This will be removed
after a deprecation period.

i2c_transfer_async is the asynchronous version of i2c_transfer where
the completion of the transfer is notified to the caller using a callback.
This can be used in conjuction with the common callbacks and datatypes
in async.h for directly doing an async transfer with an IPC object
to notify a thread.

The current atmel sam flash driver was develop based on the cortex-m7
version of smart arm microcontroller. The driver support write
protection and cache functions which is not supported by other cortex-m
variants. This fixes current driver implementation and devicetree
entries for all sam variants.
Notes:
* The cortex-m3 doesn't have support erase pages flash command and
because of that the driver still not not compatible. Keep it disabled
until a patch be send. The hwinfo driver is not affected by this
restriction.
* The sam4l variation requires a specific driver because uses another
flash controller (flashcalw). Added another compatible to
differentiate and keeped node disabled until a driver be available.
