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.
