     12description: |
     13  The FCP is a companion module of video processing modules in the Renesas
     14  R-Car Gen3 and RZ/G2 SoCs. It provides data compression and decompression,
     15  data caching, and conversion of AXI transactions in order to reduce the
     16  memory bandwidth.
     17
     18  There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and
     19  FCP for FDP (FCPF). Their configuration and behaviour depend on the module
     20  they are paired with. These DT bindings currently support the FCPV and FCPF.
