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 SoCs. It provides data compression and decompression, data caching, and
6conversion of AXI transactions in order to reduce the memory bandwidth.
7
8There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
9for FDP (FCPF). Their configuration and behaviour depend on the module they
10are paired with. These DT bindings currently support the FCPV and FCPF.
11
12 - compatible: Must be one or more of the following
13
14 - "renesas,r8a7795-fcpv" for R8A7795 (R-Car H3) compatible 'FCP for VSP'
15 - "renesas,r8a7795-fcpf" for R8A7795 (R-Car H3) compatible 'FCP for FDP'
16 - "renesas,fcpv" for generic compatible 'FCP for VSP'
17 - "renesas,fcpf" for generic compatible 'FCP for FDP'
18
19 When compatible with the generic version, nodes must list the
20 SoC-specific version corresponding to the platform first, followed by the
21 family-specific and/or generic versions.
22
23 - reg: the register base and size for the device registers
24 - clocks: Reference to the functional clock
25
26Optional properties:
27 - power-domains : power-domain property defined with a power domain specifier
28 to respective power domain.
