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.
