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