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.
