     Rockchip specific extensions to the Innosilicon HDMI
     ================================
     
     Required properties:
     - compatible:
             "rockchip,rk3036-inno-hdmi";
     - reg:
             Physical base address and length of the controller's registers.
     - clocks, clock-names:
            Phandle to hdmi controller clock, name should be "pclk"
    - interrupts:
            HDMI interrupt number
    - ports:
            Contain one port node with endpoint definitions as defined in
            Documentation/devicetree/bindings/graph.txt.
    - pinctrl-0, pinctrl-name:
            Switch the iomux of HPD/CEC pins to HDMI function.
    
    Example:
    hdmi: hdmi@20034000 {
            compatible = "rockchip,rk3036-inno-hdmi";
            reg = <0x20034000 0x4000>;
            interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>;
            clocks = <&cru  PCLK_HDMI>;
            clock-names = "pclk";
            pinctrl-names = "default";
            pinctrl-0 = <&hdmi_ctl>;
    
            hdmi_in: port {
                    #address-cells = <1>;
                    #size-cells = <0>;
                    hdmi_in_lcdc: endpoint@0 {
                            reg = <0>;
                            remote-endpoint = <&lcdc_out_hdmi>;
                    };
            };
    };
    
    &pinctrl {
            hdmi {
                    hdmi_ctl: hdmi-ctl {
                            rockchip,pins = <1 8  RK_FUNC_1 &pcfg_pull_none>,
                                            <1 9  RK_FUNC_1 &pcfg_pull_none>,
                                            <1 10 RK_FUNC_1 &pcfg_pull_none>,
                                            <1 11 RK_FUNC_1 &pcfg_pull_none>;
                    };
            };
    
    };
