+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.
