Lontium LT9611 MIPI-DSI to HDMI bridge bindings

Required properties:
 - compatible: "lontium,lt9611"
 - reg: i2c address of the bridge
 - reset-gpios: a GPIO spec for the reset pin
 - interrupts-extended: Specify the interrupts associated with external
 - vdd-supply: Reference to the regulator powering the bridge 1.8V power supply pins
 - vcc-supply: Reference to the regulator powering the bridge 3.3V power supply pins

ptional properties:
 - enable-gpios: a GPIO spec for the power supply enable control

Example:

&dsi {
	status = "okay";

	ports {
		#address-cells = <1>;
		#size-cells = <0>;

		port@1 {
			reg = <1>;
			dsi_out_lt9611: endpoint {
				remote-endpoint = <&lt9611_in_dsi>;
			};
		};
	};

};

&i2c0 {
	status = "okay";

	lontium-lt9611@39 {
		compatible = "lontium,lt9611";
		status = "okay";
		reg = <0x39>;
		interrupts-extended = <&gpio0 RK_PB5 IRQ_TYPE_EDGE_FALLING>;
		reset-gpios = <&gpio0 RK_PB6 GPIO_ACTIVE_HIGH>;
		vdd-supply = <&lt9611_1v8>;
		vcc-supply = <&lt9611_3v3>;

		ports {
			#address-cells = <1>;
			#size-cells = <0>;

			port@0 {
				reg = <0>;

				lt9611_in_dsi: endpoint {
					remote-endpoint = <&dsi_out_lt9611>;
				};
			};

		};

	};
