| description: |
| DCMI supports a single port node with parallel bus. It should contain |
| one 'port' child node with child 'endpoint' node. Please refer to the |
| bindings defined in |
| Documentation/devicetree/bindings/media/video-interfaces.txt. |
| |

| - compatible |
| - reg |
| - interrupts |
| - clocks |
| - clock-names |
| - resets |
