+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>;
+ };
