+Renesas R-Car Frame Compression Processor (FCP)
+-----------------------------------------------
+
+The FCP is a companion module of video processing modules in the Renesas R-Car
+Gen3 SoCs. It provides data compression and decompression, data caching, and
+conversion of AXI transactions in order to reduce the memory bandwidth.
+
+There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
+for FDP (FCPF). Their configuration and behaviour depend on the module they
+are paired with. These DT bindings currently support the FCPV and FCPF.
+
+ - compatible: Must be one or more of the following
+
+   - "renesas,fcpv" for generic compatible 'FCP for VSP'
+   - "renesas,fcpf" for generic compatible 'FCP for FDP'
+
+ - reg: the register base and size for the device registers
+ - clocks: Reference to the functional clock
+
+Optional properties:
+ - power-domains : power-domain property defined with a power domain specifier
+		   to respective power domain.
+
+
