0012 description: |
0013 The FCP is a companion module of video processing modules in the Renesas
0014 R-Car Gen3 and RZ/G2 SoCs. It provides data compression and decompression,
0015 data caching, and conversion of AXI transactions in order to reduce the
0016 memory bandwidth.
0017
0018 There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and
0019 FCP for FDP (FCPF). Their configuration and behaviour depend on the module
0020 they are paired with. These DT bindings currently support the FCPV and FCPF.
