1Renesas R-Car Frame Compression Processor (FCP)
2-----------------------------------------------
3
4The FCP is a companion module of video processing modules in the Renesas R-Car
5Gen3 and RZ/G2 SoCs. It provides data compression and decompression, data
6caching, and conversion of AXI transactions in order to reduce the memory
7bandwidth.
8
9There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
10for FDP (FCPF). Their configuration and behaviour depend on the module they
11are paired with. These DT bindings currently support the FCPV and FCPF.
12
13 - compatible: Must be one or more of the following
14
15   - "renesas,fcpv" for generic compatible 'FCP for VSP'
16   - "renesas,fcpf" for generic compatible 'FCP for FDP'
17
18 - reg: the register base and size for the device registers
19 - clocks: Reference to the functional clock
20
21Optional properties:
22 - power-domains : power-domain property defined with a power domain specifier
23		   to respective power domain.
