Device-Tree bindings for the NXP TDA998x HDMI transmitter

Required properties;
  - compatible: must be "nxp,tda998x"

  - reg: I2C address

Required node:
  - port: Input port node with endpoint definition, as described
        in Documentation/devicetree/bindings/graph.txt

Optional properties:
  - interrupts: interrupt number and trigger type
	default: polling

  - pinctrl-0: pin control group to be used for
	screen plug/unplug interrupt.

  - pinctrl-names: must contain a "default" entry.

  - video-ports: 24 bits value which defines how the video controller
	output is wired to the TDA998x input - default: <0x230145>

Example:

	tda998x: hdmi-encoder {
		compatible = "nxp,tda998x";
		reg = <0x70>;
		interrupt-parent = <&gpio0>;
		interrupts = <27 2>;		/* falling edge */
		pinctrl-0 = <&pmx_camera>;
		pinctrl-names = "default";
	};
