Add `hwinfo_get_reset_cause` and `hwinfo_clear_reset_cause` to retrieve
and to clear cause of system reset on supported platforms.
Different platforms can provide different causes of reset, however
there is a great deal of overlap. `enum reset_cause` can be expanded in
the future to support additional reasons, as additional platforms are
supported.

Although the master API is stable, the slave API has never been
documented and has only two in-tree implementations with no uses
outside of a single test application. It is marked experimental in
this commit.

Added information about that offsets are expressed in relation to

This info was missing which cause misunderstanding of the concept

Sphinx>=3.0 includes the `struct` role in the C domain, which provides a
specific way to link to structs, while the old :c:type: role should be
primary used to typedefs. Update existing references, using :c:type:,
:cpp:type: or emphasized symbols that point to structs to use the new
role.

This device isn't an actual hardware driver: it's a virtual EEPROM
that stores data in an instance-specific RAM buffer, with the data
exposed on an I2C bus as a I2C follower (slave) device that can be
controlled by another device acting as a leader (master) on that same
bus.
As such it's a reasonable example of how to write an I2C follower
driver, but it's not clear that it has a real use in applications. A
Zephyr application that needs to emulate an EEPROM in a real-world
system would be unlikely to provide its data from a RAM buffer.
The sole in-tree reference is in the i2c_slave_api test, so move the
driver implementation into that test.
The Kconfig and hierarchy are being left in place until it is more
clear how this functionality should be selectable within Zephyr. The
I2C_SLAVE symbol has been converted from menuconfig to config to
eliminate a Kconfig style diagnostic.

The DS3231 is an I2C real-time clock with internal temperature
compensated oscillator, maintaining civil time to 1 s precision with
nominal 2 ppm accuracy from 0-40 Cel.
The basic functionality is exposed as a counter that is always running
at 1 Hz. Much more functionality is exposed as driver-specific API,
including the ability to translate between the time scale of the DS3231
and the time scale of the Zephyr uptime clock. This allows correlation
of events in the system clock to UTC, TAI, or whatever time scale is
used to maintain the DS3231.

Remove leading/trailing blank lines in .c, .h, .py, .rst, .yml, and
.yaml files.
Will avoid failures with the new CI test in
https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only
checks changed files.
Move the 'target-notes' target in boards/xtensa/odroid_go/doc/index.rst
to get rid of the trailing blank line there. It was probably misplaced.

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.
