+title: Renesas R-Car Frame Compression Processor (FCP)
+
+maintainers:
+  - Laurent Pinchart <laurent.pinchart@ideasonboard.com>
+
+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.
+
