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.

This patch adds support for the Texas Instruments LP5030 and LP5036
I2C LED controllers. They are respectively providing up to 30 and 36
channels (i.e. 10 or 12 RGB LEDs).
In addition to the channel/color registers this LED controller provides
a per-LED brigthness register. This driver implements both LED-based and
channel-based API methods:
- led_on
- led_off
- led_get_info
- led_set_brightness
- led_set_color
- led_set_channel
- led_write_channels

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.
multi-channel) LEDs to the LED API. It allows a user to set all the
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).
Signed-off-by: Simon Guinot <simon.guinot@seagate.com>
When supported by the driver the led_get_info syscall allows a user
to retrieve the following information about each LED available:
- The LED label.
- The number of colors/channels.
- And for a multicolor LED a pointer to a channel-color mapping.

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.

The spi_flash_w25qxxdv driver has been superseded by the generic
spi_nor driver for over a year. The only non-refactoring change to
the W25Q driver in the last 18 months was done to support a backport
to 1.14.
All devices supported by spi_flash_w25qxxdv driver are expected to be
supported by the spi_nor driver, using the standard `jedec,spi-nor`
devicetree compatible. No in-tree devicetree files make use of this
driver.

As a general rule devicetree properties should correspond to hardware
description or configuration. In cases where a Zephyr driver receives
instance-specific configuration data from a devicetree property that
property should be marked as being Zephyr-specific. Rename

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.

The condition of being either the last message or not concatenable to
the next message is the inverse of the condition of committing to

The device may be prematurely configured before it is ready during
reset without first checking. After the driver writes to the registers
and normal mode gets selected, CANSTAT is read back to ensure the
device is now configured in normal mode (0x00). However, an
unresponsive device will be read as 0x00, the driver then assumes it is
configured correctly.
The MCP2515 will reset into configuration mode (0x04) to allow bit
timings to be configured. Adding a check for this mode prevents the
device from being misconfigured.

ringbuf claim API returns pointer to contiguous area. In cases when data
in ringbuf wraps the end of internal buffer, then single call to claim
data is not enough to get all data - there is remaining part on the
beginning of internal buffer. Those remaining bytes will need to wait
for next ISR handler to trigger workqueue. Theoretically this means that
data on the beginning of ringbuf can wait there forever.
Consume data from ringbuf in a loop, stopping only when claiming results
in empty buffer. This will make sure that there is no stale data in the
ringbuf.

The magnetometer vector-magnitude function will generate an interrupt
when magnitude is greater than specified threshold value. The user
may program the threshold value to establish the conditions needed
to detect a magnetic vector-magnitude change event. Depending on the
values chosen for the reference values, this function may be
configured to detect a magnetic field magnitude that is above
a preset threshold (with reference values = 0), or a change in magnitude
between two magnetic vectors greater than the preset threshold
(with reference values non-zero).
