Mauro Carvalho Chehab 32e2eae23f media: docs: move user-facing docs to the admin guide
Most of the driver-specific documentation is meant to help
users of the media subsystem.

Move them to the admin-guide.

It should be noticed, however, that several of those files
are outdated and will require further work in order to make
them useful again.

Renesas R-Car Fine Display Processor (FDP1) Driver
==================================================
The R-Car FDP1 driver implements driver-specific controls as follows.
``V4L2_CID_DEINTERLACING_MODE (menu)``
The video deinterlacing mode (such as Bob, Weave, ...). The R-Car FDP1
driver implements the following modes.
.. flat-table::
:header-rows: 0
:stub-columns: 0
:widths: 1 4
* - ``"Progressive" (0)``
- The input image video stream is progressive (not interlaced). No
deinterlacing is performed. Apart from (optional) format and encoding
conversion output frames are identical to the input frames.
* - ``"Adaptive 2D/3D" (1)``
- Motion adaptive version of 2D and 3D deinterlacing. Use 3D deinterlacing
in the presence of fast motion and 2D deinterlacing with diagonal
interpolation otherwise.
* - ``"Fixed 2D" (2)``
- The current field is scaled vertically by averaging adjacent lines to
recover missing lines. This method is also known as blending or Line
Averaging (LAV).
* - ``"Fixed 3D" (3)``
- The previous and next fields are averaged to recover lines missing from
the current field. This method is also known as Field Averaging (FAV).
* - ``"Previous field" (4)``
- The current field is weaved with the previous field, i.e. the previous
field is used to fill missing lines from the current field. This method
is also known as weave deinterlacing.
* - ``"Next field" (5)``
- The current field is weaved with the next field, i.e. the next field is
used to fill missing lines from the current field. This method is also
known as weave deinterlacing.
