Use the pre_streamon callback to transition the transmitter to either
LP-11 or LP-111 mode if supported by the sensor.

Add pre_streamon and post_streamoff callbacks that can be used to set a
CSI-2 transmitter to LP-11 or LP-111 mode. This can be used by receiver
drivers to reliably initialise the receiver when its initialisation
requires software involvement.

Rework LP-11 and LP-111 mode documentation to make it more understandable
and useful. This involves adding pre_streamon and post_streamon callbacks
that make it possible to explicitly transition the transmitter to either
mode.

The V4L2_CID_PIXEL_RATE is nowadays used to tell pixel sampling rate in
the sub-device's pixel array, not the pixel rate over a link (for which it
also becomes unfit with the addition of multiplexed streams later on). Fix
this.

Modernise the documentation to make it more precise and update the use of
pixel rate control and various other changes. In particular:
- Use non-proportional font for file names, properties as well as
controls.
- The unit of the HBLANK control is pixels, not lines.
- The unit of PIXEL_RATE control is pixels per second, not Hz.
- Merge common requirements for CSI-2 and parallel busses.
- Include all DT properties needed for assigned clocks.
- Fix referencing the link rate control.
- SMIA driver's new name is CCS driver.
- The PIXEL_RATE control denotes pixel rate on the pixel array on camera
sensors. Do not suggest it is used to tell the maximum pixel rate on the
bus anymore.
- Improve ReST syntax (plain struct and function names).
- Remove the suggestion to use s_power() in receiver drivers.
- Make MIPI website URL use HTTPS, add Wikipedia links to BT.601 and
BT.656.

According to media bus pixel codes definition, data formats on serial
busses should be described with one bus sample per pixel.
Documentation/userspace-api/media/v4l/subdev-formats.rst states:
"The media bus pixel codes document parallel formats. Should the pixel
data be transported over a serial bus, the media bus pixel code that
describes a parallel format that transfers a sample on a single clock
cycle is used. For instance, both MEDIA_BUS_FMT_BGR888_1X24 and
MEDIA_BUS_FMT_BGR888_3X8 are used on parallel busses for transferring an
8 bits per sample BGR data, whereas on serial busses the data in this
format is only referred to using MEDIA_BUS_FMT_BGR888_1X24. This is
because there is effectively only a single way to transport that
format on the serial busses."
Some MIPI CSI receivers strictly obey this definition and declare
support for only *1X_* formats.
Hence, complement the supported media bus formats with their 1X16 versions
(currently applicable to yuyv, uyvy) to enhance interoperability with CSI
receivers.

If em28xx_ir_init fails, it would decrease the refcount of dev. However,
in the em28xx_ir_fini, when ir is NULL, it goes to ref_put and decrease
the refcount of dev. This will lead to a refcount bug.
Fix this bug by removing the kref_put in the error handling code
of em28xx_ir_init.
refcount_t: underflow; use-after-free.

This patch adds the driver for Amlogic Meson IR transmitter.
Some Amlogic SoCs such as A311D and T950D4 have IR transmitter
(also called blaster) controller onboard. It is capable of sending
IR signals with arbitrary carrier frequency and duty cycle.
The driver supports 2 modulation clock sources:
- xtal3 clock (xtal divided by 3)
- 1us clock
