[media] v4l: Add Renesas R-Car FDP1 Driver 



The FDP1 driver performs advanced de-interlacing on a memory 2 memory
based video stream, and supports conversion from YCbCr/YUV
to RGB pixel formats

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.
