'minItems' alone does not impose upper bound, unlike 'maxItems' which
implies lower bound. Add missing clock constraint so the list will have
exact number of items (clocks).

|
LCD interface.

A port node with endpoint definitions as defined in

Documentation/devicetree/bindings/media/video-interfaces.txt.
|

That port should be the output endpoint, usually output to
|
|
the associated DSI.
