title: Renesas R-Car ISP Channel Selector
maintainers:
- Niklas Söderlund <niklas.soderlund@ragnatech.se>
description:
The R-Car ISP Channel Selector provides MIPI CSI-2 VC and DT filtering
capabilities for the Renesas R-Car family of devices. It is used in
conjunction with the R-Car VIN and CSI-2 modules, which provides the video
capture capabilities.
