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>; + }; |
