   9 Required properties:
  10  - #address-cells : should be <1>
  11  - #size-cells : should be <0>
  12  - compatible : should be "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi".
  13  - gpr : should be <&gpr>.
  14    The phandle points to the iomuxc-gpr region containing the HDMI
  15    multiplexer control register.
  16  - clocks, clock-names : phandles to the HDMI iahb and isrf clocks, as described
  17    in Documentation/devicetree/bindings/clock/clock-bindings.txt and
  18    Documentation/devicetree/bindings/clock/imx6q-clock.txt.
  19  - port@[0-4]: Up to four port nodes with endpoint definitions as defined in
  20    Documentation/devicetree/bindings/media/video-interfaces.txt,
  21    corresponding to the four inputs to the HDMI multiplexer.
