• Nodes

• ports:
  Usage: required
  Definition: As described in video-interfaces.txt in same directory.
  Properties:

    - reg:
        Usage: required
        Value type: <u32>
        Definition: Selects CSI2 PHY interface - PHY0 or PHY1.
  

  Endpoint node properties:

    - clock-lanes:
        Usage: required
        Value type: <u32>
                    Definition: The physical clock lane index. The value
                                must always be <1> as the physical clock
                                lane is lane 1.
    - data-lanes:
        Usage: required
        Value type: <prop-encoded-array>
                    Definition: An array of physical data lanes indexes.
                                Position of an entry determines the logical
                                lane number, while the value of an entry
                                indicates physical lane index. Lane swapping
                                is supported.
