Renesas R-Car Frame Compression Processor (FCP)

-----------------------------------------------

The FCP is a companion module of video processing modules in the Renesas R-Car

Gen3 and RZ/G2 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.

Device node example

-------------------

	fcpvd1: fcp@fea2f000 {

		compatible = "renesas,fcpv";

		reg = <0 0xfea2f000 0 0x200>;

		clocks = <&cpg CPG_MOD 602>;

		power-domains = <&sysc R8A7795_PD_A3VP>;
