It provides data compression and decompression, 15*4882a593Smuzhiyun data caching, and conversion of AXI transactions in order to reduce the 16*4882a593Smuzhiyun memory bandwidth. 17*4882a593Smuzhiyun 18*4882a593Smuzhiyun There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and 19*4882a593Smuzhiyun FCP for FDP (FCPF). Their configuration and behaviour depend on the module 20*4882a593Smuzhiyun they are paired with. These DT bindings currently support the FCPV and FCPF. 21*4882a593Smuzhiyun 22*4882a593Smuzhiyunproperties: 23*4882a593Smuzhiyun compatible: 24*4882a593Smuzhiyun enum: 25*4882a593Smuzhiyun - renesas,fcpv # FCP for VSP 26*4882a593Smuzhiyun - renesas,fcpf # FCP for FDP 27*4882a593Smuzhiyun 28*4882a593Smuzhiyun reg: 29*4882a593Smuzhiyun maxItems: 1 30*4882a593Smuzhiyun 31*4882a593Smuzhiyun clocks: 32*4882a593Smuzhiyun maxItems: 1 33*4882a593Smuzhiyun 34*4882a593Smuzhiyun iommus: 35*4882a593Smuzhiyun maxItems: 1 36*4882a593Smuzhiyun 37*4882a593Smuzhiyun power-domains: 38*4882a593Smuzhiyun maxItems: 1 39*4882a593Smuzhiyun 40*4882a593Smuzhiyun resets: 41*4882a593Smuzhiyun maxItems: 1 42*4882a593Smuzhiyun 43*4882a593Smuzhiyunrequired: 44*4882a593Smuzhiyun - compatible 45*4882a593Smuzhiyun - reg 46*4882a593Smuzhiyun - clocks 47*4882a593Smuzhiyun - power-domains 48*4882a593Smuzhiyun - resets 49*4882a593Smuzhiyun 50*4882a593SmuzhiyunadditionalProperties: false 51*4882a593Smuzhiyun 52*4882a593Smuzhiyunexamples: 53*4882a593Smuzhiyun # R8A7795 (R-Car H3) FCP for VSP-D1 54*4882a593Smuzhiyun - | 55*4882a593Smuzhiyun #include <dt-bindings/clock/renesas-cpg-mssr.h> 56*4882a593Smuzhiyun #include <dt-bindings/power/r8a7795-sysc.h> 57*4882a593Smuzhiyun 58*4882a593Smuzhiyun fcp@fea2f000 { 59*4882a593Smuzhiyun compatible = "renesas,fcpv"; 60*4882a593Smuzhiyun reg = <0xfea2f000 0x200>; 61*4882a593Smuzhiyun clocks = <&cpg CPG_MOD 602>; 62*4882a593Smuzhiyun power-domains = <&sysc R8A7795_PD_ALWAYS_ON>; 63*4882a593Smuzhiyun resets = <&cpg 602>; 64*4882a593Smuzhiyun iommus = <&ipmmu_vi0 9>; 65*4882a593Smuzhiyun }; 66*4882a593Smuzhiyun... 67
