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>;
		};
	};
