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