-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>;
