+title: Renesas R-Car MIPI CSI-2 receiver
+
+maintainers:
+ - Niklas Söderlund <niklas.soderlund@ragnatech.se>
+
+description:
+ The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
+ Renesas R-Car and RZ/G2 family of devices. It is used in conjunction with the
+ R-Car VIN module, which provides the video capture capabilities.
