5fbc9346d0 drivers: can: Fix device instance const qualifier loss in MCUX Flexcan
It is necessary to wrap the device pointer into data, and pass the data
to the HAL callback function.

206f4d61fc drivers: i2c: Fix device instance const qualifier loss
In all of these drivers, passing the device's data was sufficient as
only the data is being used by the HAL callback function then.

9ac8dcf5a7 Bluetooth: Call bt_recv from priority higher that TX thread.
A build assert in dummy.c lists the following requirement:
[...] receive thread priority shall be higher than the Bluetooth
Host's Tx and the Controller's receive thread priority.
This is required in order to dispatch Number of Completed Packets
event before any new data arrives on a connection to the Host threads.

The drivers uses a priority that is equal to the Host TX thread,
and since they don't use the CONFIG define that is only available
to the controller then this BUILD_ASSERT will not catch the
requirement.

84d90e456a driver: intc: add MIWU driver support in NPCX series.
The device Multi-Input Wake-Up Unit (MIWU) supports the embedded
controller (EC) to exit 'Sleep' or 'Deep Sleep' power state which allows
chip has better power consumption. Also, it provides signal conditioning
such as 'Level' and 'Edge' trigger type and grouping of external
interrupt sources of NVIC. The NPCX series has three identical MIWU
modules: MIWU0, MIWU1, MIWU2. Together, they support a total of over 140
internal and/or external wake-up sources.

In this CL, we use device tree files to present the relationship bewteen
MIWU and the other devices in different npcx series. For npcx7 series,
it include:
1. npcx7-miwus-int-map.dtsi: it presents relationship between MIWU group
   and NVIC interrupt in npcx7. Please notice it isn't 1-to-1 mapping.
2. npcx7-miwus-wui-map.dtsi: it presents relationship between input of
   MIWU and its source device such as gpio, timer, eSPI VWs and so on.

This CL also includes:
1. Add MIWU device tree declarations.
2. MIWU api function declarations and implementation to configure signal
   conditions and callback function mechanism. They can be be classified
   into two types. One is for GPIO which connects original gpio callback
   implemetation and the other is for generic devices such as timer,
   eSPI, and so on.

f59abf5916 drivers: led: introduce channel-dedicated syscalls
Some LED controllers are connected to a large number of LEDs (i.e.
array/strip of LEDs). A user may need to set several LEDs at the same
time. The LED oriented syscalls are not adapted to this task. Indeed a
call per LED is needed to configure a group of LEDs. To that end, this
patch adds the led_set_channel and led_write_channels syscalls to the
LED API. They offer direct access to the raw channels. They respectively
allow to set a single channel and to write several contiguous channels
(and therefore to configure a group of LEDs).

Moreover the addition of the led_write_channels syscall also aims at
closing the gap with the LED strip API.

The led_set_color syscall adds support for multicolor (i.e.

colors/channels of a LED at once by passing a color array. Note that
this array must provide an entry per color/channel and must also be
ordered following the color mapping of the LED. This color mapping can
be either retrieved from the "color-mapping" DT property or from the LED
driver itself (by using the led_get_info syscall).

1603c329bd drivers: i2c_ll_stm32_v2: add support for optional timing property
In case optional timings property has been defined in DT, let's use it
and look for a matching peripheral clock and i2c bus clock so that
timing value is used instead of using runtime algorithm.

If matching the current configuration, the value will be set directly to
the I2C_TIMINGR register through the LL API.

This property is only valid for I2C V2 peripheral, so the timing config
structure member is only added in case of CONFIG_I2C_STM32_V2. Also the
initialization of the member is done conditionnaly, only in case
it is defined in DT, otherwise timings table will be empty.

afdb98a4a9 drivers: i2c_nrfx_twim: restore previous behavior without concat buffer
The Nordic TWIM peripheral generates a start condition for each bus
transaction.  Devices such as the SSD1306 display and some NXP sensors
can only tolerate the presence of a start condition and device address
after a stop condition.  Those devices will not operate correctly when
these signals are observed while the bus is already active.  This
motivated the addition of a RAM buffer into which message fragments
could be collected so TWIM can transmit them without injecting
unnecessary start conditions.

However many I2C devices interpret these signals as a repeated start
and ignore them and so function properly without a buffer
concatenating the message fragments.

There is no default for the concat-buf-size property, and the previous
strict requirement for one when performing scatter/gather I/O
transactions broke working drivers for devices that tolerate the
repeated starts.  Allow those drivers to work by respecting the
property description and attempting to concatenate messages only if a
buffer in which to place them has been provided.
