1Renesas R-Car Frame Compression Processor (FCP) 2----------------------------------------------- 3 4The FCP is a companion module of video processing modules in the Renesas R-Car 5Gen3 and RZ/G2 SoCs. It provides data compression and decompression, data 6caching, and conversion of AXI transactions in order to reduce the memory 7bandwidth. 8 9There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP 10for FDP (FCPF). Their configuration and behaviour depend on the module they 11are paired with. These DT bindings currently support the FCPV and FCPF. 12 13 - compatible: Must be one or more of the following 14 15 - "renesas,fcpv" for generic compatible 'FCP for VSP' 16 - "renesas,fcpf" for generic compatible 'FCP for FDP' 17 18 - reg: the register base and size for the device registers 19 - clocks: Reference to the functional clock 20 21Optional properties: 22 - power-domains : power-domain property defined with a power domain specifier 23 to respective power domain. 24 25 26Device node example 27------------------- 28 29 fcpvd1: fcp@fea2f000 { 30 compatible = "renesas,fcpv"; 31 reg = <0 0xfea2f000 0 0x200>; 32 clocks = <&cpg CPG_MOD 602>; 33 power-domains = <&sysc R8A7795_PD_A3VP>; 34 }; 35
