    1 Renesas R-Car Frame Compression Processor (FCP)
    2 -----------------------------------------------
    3 
    4 The FCP is a companion module of video processing modules in the Renesas R-Car
    5 Gen3 and RZ/G2 SoCs. It provides data compression and decompression, data
    6 caching, and conversion of AXI transactions in order to reduce the memory
    7 bandwidth.
    8 
    9 There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
   10 for FDP (FCPF). Their configuration and behaviour depend on the module they
   11 are 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 
   21 Optional properties:
   22  - power-domains : power-domain property defined with a power domain specifier
   23                    to respective power domain.
