I would drop the "for" part, and just write e.g. "# FCP for VSP".

-Renesas R-Car Frame Compression Processor (FCP)
------------------------------------------------
-
-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.
-
- - 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.
-
-
-Device node example
--------------------
-
-	fcpvd1: fcp@fea2f000 {
