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.

	Contains one port node with one endpoint

	connected to a hdmi-connector node.

- 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>;

		ports {

			#address-cells = <1>;

			#size-cells = <0>;

			hdmi_in: port@0 {

				reg = <0>;

				hdmi_in_vop1: endpoint@1 {

					reg = <1>;

					remote-endpoint = <&vop1_out_hdmi>;

				};

			};

			hdmi_out: port@1 {

				reg = <1>;

				hdmi_out_con: endpoint {

					remote-endpoint = <&hdmi_con_in>;

				};

			};

		};

	};

&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>;

			};

		};
