This is a specific case for NVMe where given data buffer pointers must
be dword (4 bytes) aligned.
There is no virtual memory management between the user thread and NVMe
driver (which one could detect such wrong alignement on physical memory
and thus reallocate the memory properly, so it would be fully
transparent for the user thread), thus the need to push that check to
the user.
This has been going under the radar so far as Qemu does not seem to
follow NVMe specifications where PRP1 (in DPTR) must always be
dword-aligned. It really does not follow the rule: specifications
details that if bits 1:0 of PRP1 are set, the controller may generate
an error or treat the address as if these bits were unset. Seems like
a bug in Qemu, I did not check the code there however.

Remove temp-, vref- and vbat-channel from STM32 ADC nodes as it is not
used in the driver anymore.
Signed-off-by: Guillaume Gautier <guillaume.gautier-ext@st.com>
On some STM32 families (such as F4), temperature and Vbat sensor share the
same ADC channel, which can lead to conflict when reading them, and wrong
measurement can follow.
To alleviate this problem, this commit moves the setting of the common
path internal channel to the sensor drivers themselves instead of doing
it in the ADC driver.
The teardown is still done in the ADC driver, systematically, instead of
channel by channel (which has the same result).
By moving this logic in the sensor drivers, the properties temp-channel,
vbat-channel and vref-channel becomes useless and are thus removed.

Because devices share the same underlying infrastructure with SYS_INIT,
the same levels have always been available. However, not all of them are
needed, and some are not even usable. For example, `EARLY` can't be used
because when initialized `z_device_state_init` has not been called yet.
`SMP` has never been used by device drivers, and it is now in question,
likely to be moved to SMP specific hooks. Finally, `APPLICATION` does
not make much sense in the context of Kernel devices. Note that of the 3
levels just mentioned, only one was actively tested (`APPLICATION`) by
Kernel tests, meaning others were likely never considered in the context
of devices.
This patch leaves `PRE_KERNEL_1`, `PRE_KERNEL_2` and `POST_KERNEL`
available to devices. Others have been deprecated, and will generate a
compiler warning if used.

Introduce hwinfo driver for Texas Instruments SimpleLink CC13xx/CC26xx
SOC series, with support for retrieving device's ID and cause of reset.
By default, the pre-programmed, 8-bytes length IEEE MAC address is used
for device's ID, with option ('HWINFO_CC13XX_CC26XX_USE_BLE_MAC') for
use 6-bytes length BLE MAC instead. By default, read-only values stored
in FCFG (Factory Configuration) are used but additional Kconfig option
('HWINFO_CC13XX_CC26XX_ALWAYS_USE_FACTORY_DEFAULT') is also provided,
which allows to use values from writable CCFG (Customer Configuration)
area. In all cases, device ID value is provided in big-endian which
matches what TI's UniFlash tool returns.
For reset cause, 'SysCtrlResetSourceGet()' function from TI's driver
library is used and its value is mapped to Zephyr's implementation.
Importantly, only root cause of reset is available on CC13xx/CC26xx
platform as described in MCU Technical Reference Manual ('RESET_SRC'
field in 'RESETCTL' register):
"Shows the root cause of the last system reset. More than the
reported reset source can have been active during the last
system reset but only the root cause is reported."

Deprecate the advanced CAN timing devicetree properties in favor of setting
advanced timing parameters from application code.
The advanced timing properties are giving in number of time quanta (Tq) and
requires reverse-calculation to find a suitable CAN clock divider. The
resulting bitrate error is compared against a threshold in the driver
initialization code, but the application is not able to retrieve it.
Forcing applications to use the CAN timing APIs directly instead makes it
up to the application to determine if the bitrate error is acceptable or
not.
The deprecated properties are:
- prop-seg
- phase-seg1
- phase-seg2
- prop-seg-data
- phase-seg1-data
- phase-seg2-data
