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.
