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 transaction in order to reduce the memory
bandwidth.

+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 transaction in order to reduce the memory bandwidth.
+
+There are three types of FCP whose configuration and behaviour highly depend
+on the module they are paired with.
+
+ - compatible: Must be one or more of the following
+
+ - "renesas,r8a7795-fcpv" for R8A7795 (R-Car H3) compatible 'FCP for VSP'
+ - "renesas,fcpv" for generic compatible 'FCP for VSP'
+
+ When compatible with the generic version, nodes must list the
+ SoC-specific version corresponding to the platform first, followed by the
+ family-specific and/or generic versions.
+
+ - reg: the register base and size for the device registers
+ - clocks: Reference to the functional clock
+
+
+Device node example
+-------------------
+
+ fcpvd1: fcp@fea2f000 {
+ compatible = "renesas,r8a7795-fcpv", "renesas,fcpv";
+ reg = <0 0xfea2f000 0 0x200>;
+ clocks = <&cpg CPG_MOD 602>;
+ };
