+Rockchip specific extensions for rk3066 HDMI
+============================================
+
+Required properties:
+- compatible:
+ "rockchip,rk3066-hdmi";
+- reg:
+ Physical base address and length of the controller's registers.
+- clocks, clock-names:
+ Phandle to HDMI controller clock, name should be "hclk".
+- interrupts:
+ HDMI interrupt number.
+- power-domains:
+ Phandle to the RK3066_PD_VIO power domain.
+- rockchip,grf:
+ This soc uses GRF regs to switch the HDMI TX input between vop0 and vop1.
+- ports:
+ Contains one port node with two endpoints, numbered 0 and 1,
+ connected respectively to vop0 and vop1.
+- pinctrl-0, pinctrl-name:
+ Switch the iomux for the HPD/I2C pins to HDMI function.
+
+Example:
+ hdmi: hdmi@10116000 {
+ compatible = "rockchip,rk3066-hdmi";
+ reg = <0x10116000 0x2000>;
+ interrupts = <GIC_SPI 64 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&cru HCLK_HDMI>;
+ clock-names = "hclk";
+ power-domains = <&power RK3066_PD_VIO>;
+ rockchip,grf = <&grf>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&hdmii2c_xfer>, <&hdmi_hpd>;
+ status = "disabled";
+
+ hdmi_in: port {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ hdmi_in_vop0: endpoint@0 {
+ reg = <0>;
+ remote-endpoint = <&vop0_out_hdmi>;
+ };
+ hdmi_in_vop1: endpoint@1 {
+ reg = <1>;
+ remote-endpoint = <&vop1_out_hdmi>;
+ };
+ };
+ };
+
+&pinctrl {
+ hdmi {
+ hdmi_hpd: hdmi-hpd {
+ rockchip,pins = <0 RK_PA0 1 &pcfg_pull_default>;
+ };
+ hdmii2c_xfer: hdmii2c-xfer {
+ rockchip,pins = <0 RK_PA1 1 &pcfg_pull_none>,
+ <0 RK_PA2 1 &pcfg_pull_none>;
+ };
+ };
+};
