13description:
14  The R-Car Video Input (VIN) device provides video input capabilities for the
15  Renesas R-Car family of devices.
16
17  Each VIN instance has a single parallel input that supports RGB and YUV video,
18  with both external synchronization and BT.656 synchronization for the latter.
19  Depending on the instance the VIN input is connected to external SoC pins, or
20  on Gen3 and RZ/G2 platforms to a CSI-2 receiver.
