Renesas R-Car Frame Compression Processor (FCP)
|
|
-----------------------------------------------
|
|
|
|
The FCP is a companion module of video processing modules in the Renesas R-Car
|
|
Gen3 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.
|
|
|
|
- compatible: Must be one or more of the following
|
|
|
|
- "renesas,fcpv" for generic compatible 'FCP for VSP'
|
|
- "renesas,fcpf" for generic compatible 'FCP for FDP'
|
|
|
|
- reg: the register base and size for the device registers
|
|
- clocks: Reference to the functional clock
|
|
|
|
Optional properties:
|
|
- power-domains : power-domain property defined with a power domain specifier
|
|
to respective power domain.
