Bummer, we don't have family-specific compatible values to enforce this
in yaml ;-)

-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.
