Lad Prabhakar ae8694393e media: dt-bindings: media: renesas,fcp: Allow three clocks for RZ/V2N SoC
Update the FCP DT schema to permit three clock inputs for the RZ/V2N SoC.
The FCP block on this SoC requires three separate clocks, unlike other
variants which use only one.

description: |
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.
