   9 Optional properties:
  10  - clocks: Reference to the input clock as specified by
  11            Documentation/devicetree/bindings/clock/clock-bindings.txt.
  12  - clock-names: Names of the clocks used; "axi" for the AXI bus interface,
  13                 "func" for the peripheral clock and "phy" for the parallel
  14                 video bus interface.

  16
  17 Required subnodes:
  18  - port: The parallel bus interface port with a single endpoint linked to
  19          the sensor's endpoint as described in
  20          Documentation/devicetree/bindings/media/video-interfaces.txt.
  21
  22 Required endpoint properties:
  23  - bus-type: data bus type, <5> or <6> for Parallel or Bt.656 respectively
  24  - pclk-sample: pixel clock polarity
  25  - hsync-active: horizontal synchronization polarity (only required for
  26    parallel bus)
  27  - vsync-active: vertical synchronization polarity (only required for
  28    parallel bus)
