media: rcar-csi2: add Renesas R-Car MIPI CSI-2 receiver documentation
Documentation for Renesas R-Car MIPI CSI-2 receiver. The CSI-2 receivers
are located between the video sources (CSI-2 transmitters) and the video
grabbers (VIN) on Gen3 of Renesas R-Car SoC.
Each CSI-2 device is connected to more than one VIN device which
simultaneously can receive video from the same CSI-2 device. Each VIN
device can also be connected to more than one CSI-2 device. The routing
of which links are used is controlled by the VIN devices. There are only
a few possible routes which are set by hardware limitations, which are
different for each SoC in the Gen3 family.
