progressive video. It is capable of performing pixel format conversion between
YCbCr/YUV formats and RGB formats. Only YCbCr/YUV formats are supported as
an input to the module.
Required properties:
- compatible: must be "renesas,fdp1"
- reg: the register base and size for the device registers

any.
- renesas,fcp: a phandle referencing the FCP that handles memory accesses
for the FDP1. Not needed on Gen2, mandatory on Gen3.
Please refer to the binding documentation for the clock and/or power domain
providers for more details.

MIPI CSI-2
==========
CSI-2 is a data bus intended for transferring images from cameras to
the host SoC. It is defined by the `MIPI alliance`_.
.. _`MIPI alliance`: http://www.mipi.org/
Transmitter drivers
-------------------
CSI-2 transmitter, such as a sensor or a TV tuner, drivers need to
provide the CSI-2 receiver with information on the CSI-2 bus
configuration. These include the V4L2_CID_LINK_FREQ and
V4L2_CID_PIXEL_RATE controls and
(:c:type:`v4l2_subdev_video_ops`->s_stream() callback). These
interface elements must be present on the sub-device represents the
CSI-2 transmitter.
The V4L2_CID_LINK_FREQ control is used to tell the receiver driver the
frequency (and not the symbol rate) of the link. The
V4L2_CID_PIXEL_RATE is may be used by the receiver to obtain the pixel
rate the transmitter uses. The
:c:type:`v4l2_subdev_video_ops`->s_stream() callback provides an
ability to start and stop the stream.
The value of the V4L2_CID_PIXEL_RATE is calculated as follows::
pixel_rate = link_freq * 2 * nr_of_lanes / bits_per_sample
where
.. list-table:: variables in pixel rate calculation
:header-rows: 1
* - variable or constant
- description
* - link_freq
- The value of the V4L2_CID_LINK_FREQ integer64 menu item.
* - nr_of_lanes
- Number of data lanes used on the CSI-2 link. This can
be obtained from the OF endpoint configuration.
* - 2
- Two bits are transferred per clock cycle per lane.
* - bits_per_sample
- Number of bits per sample.
The transmitter drivers must configure the CSI-2 transmitter to *LP-11
mode* whenever the transmitter is powered on but not active. Some
transmitters do this automatically but some have to be explicitly
programmed to do so.
Receiver drivers
----------------
Before the receiver driver may enable the CSI-2 transmitter by using
the :c:type:`v4l2_subdev_video_ops`->s_stream(), it must have powered
the transmitter up by using the
:c:type:`v4l2_subdev_core_ops`->s_power() callback. This may take
place either indirectly by using :c:func:`v4l2_pipeline_pm_use` or
directly.

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)``
