+Required properties:

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

+example:

•   gpr: iomuxc-gpr@020e0000 {
  

•           /* ... */
  

•   };
  

•    hdmi: hdmi@0120000 {
  

•            #address-cells = <1>;
  

•            #size-cells = <0>;
  

•            reg = <0x00120000 0x9000>;
  

•            interrupts = <0 115 0x04>;
  

•            gpr = <&gpr>;
  

•            clocks = <&clks 123>, <&clks 124>;
  

•            clock-names = "iahb", "isfr";
  

The 'compatible' property is missing in the example.
