+Renesas R-Car Fine Display Processor (FDP1)
+-------------------------------------------
+
+The FDP1 is a de-interlacing module which converts interlaced video to
+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
+ - interrupts : interrupt specifier for the FDP1 instance
+ - clocks: reference to the functional clock
+
+Optional properties:
+
+ - power-domains: reference to the power domain that the FDP1 belongs to, if
+                  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.
