media: dt-bindings: media: renesas,isp: Add bindings for ISP Channel Selector
Add bindings for Renesas R-Car ISP Channel Selector IP. The ISP is responsible for filtering the MIPI CSI-2 bus and directing the different CSI-2 virtual channels to different R-Car VIN instances (DMA engines) for capture.

+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.
