ac5acb9530 drivers: sensor: ccs811: provide API to fetch configuration and versions
The application may want to know the configured mode without inspecting
Kconfig macros; this is important for proper management of BASELINE
which is mode-dependent.

It also may need to know the version of the hardware and firmware, as
the behavior of application firmware 2.0 is significantly better than
version 1.1.

2dd990ad55 drivers: sensor: ccs811: enable drive mode 4
This mode is documented as producing a raw result every 250 ms that the
application must convert to eCO2 and eTVOC readings.  In practice

cb84836745 drivers: sensor: ccs811: provide access to sensor results
Expose the entire content of the ALG_RESULT_DATA block to the
application, primarily so the status and error flags can be seen.  With
those available the application has the ability to detect that a stale
result has been provided so sensor_fetch_sample() can return -EAGAIN in
this case instead of -EIO, and it doesn't need to block which is
annoying.

This should also make the sensor usable on older Nordic Thingy:52
devices with outdated CCS811 application firmware that doesn't properly
implement the DATA_READY bit.

Proper use of the CCS811 requires maintenance of the BASELINE

db611e6781 drivers: pwm: add support for inverted PWM signals
Add support for requesting an inverted PWM pulse (active-low) when
setting up the period and pulse width of a PWM pin. This is useful
when driving external, active-low circuitry (e.g. an LED) with a PWM
signal.

All in-tree PWM drivers is updated to match the new API signature, but
no driver support for inverted PWM signals is added yet.

All in-tree PWM consumers are updated to pass a flags value of 0
(0 meaning default, which is normal PWM polarity).

Fixes #21384.

00156ad80a drivers: clock_control: nrf: Switch to single clock device
Low frequency and high frequency clocks had separate devices
while they are actually handled by single peripheral with single
interrupt. The split was done probably because opaque subsys
argument in the API was used for other purposes and there was
no way to pass the information which clock should be controlled.
Implementation changes some time ago and subsys parameter was
no longer used. It now can be used to indicate which clock should
be controlled.

Change become necessary when nrf5340 is taken into account where
there are more clocks and current approach would lead to create
multiple devices - mess.

32e3756d66 include: Fixes #1205, C++ usage of sensor.h
I ran into issue #1205 earlier today and realized the fix was to simply
provide the proper casts.  The issue is that C++ is less permissive than
C here, erroring when trying to implicitly convert from `void *` to
`struct gpio_driver_api *`.  The same cast is done in
include/drivers/gpio.h, which is why I did that here as well.

This fix was validated by compiling my C++ application successfully and
also successfully running my app on my board, interacting with sensors.

32169886ca drivers: Add video API
This generic video API can be used to capture/output video frames.

Once a video buffer is enqueued to a video device endpoint, device owns
the buffer and can process to capture (camera), output (disk, display),
convert (hw encoder)... User can then call dequeue to retrieve
the processed buffer (video driver ensure cache coherency).

Once dequeued, video buffer is owned by user (e.g. for frame
processing, display buffer update, write to media, etc...).

For each video-buffer, user needs allocate the associated frame buffer
via video_buffer_alloc. Buffer format is defined by video device
endpoint configuration. Video device can be controlled (e.g. contrast,
brightness, flip...) via controls.
