+Rockchip specific extensions to the Innosilicon HDMI
+================================
+
+Required properties:
+- compatible:
+       "rockchip,rk3036-dw-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>;
+       status = "disabled";
+
+       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>;
+               };
+       };

+};
