Silicon Image SiI9022 HDMI Encoder
==================================

Silicon Image SiI9022 is an HDMI encoder that encodes parallel RGB
signal to HDMI signal. The SiI9022 is controlled with i2c command, and
it has a single reset pin and single interrupt pin.

Required properties:
- compatible: "sil,sii9022"

Optional properties:
- reset-gpio: reset gpio
- interrupts: interrupt line

Required for HDMI audio:
- i2s-fifo-routing:
  - Array of exactly 4 integers indicating i2s pins to audio fifo routing
  - First integer defines routing to fifo 0 and second to fifo 1, etc.
  - Integers can be filled with definitions from:
    include/dt-bindings/sound/sii9022-audio.h

Required nodes:
- Video port 0 for parallel video input
- Video port 1 for HDMI output

Example
-------

&i2c2 {
	sii9022: sii9022@3b {
		compatible = "sil,sii9022";
		reg = <0x3b>;

		i2s-fifo-routing = <
			(ENABLE_BIT|CONNECT_SD0)
			0
			0
			0
		>;

		reset-gpio = <&gpio2 1 GPIO_ACTIVE_LOW>;

		interrupt-parent = <&gpio1>;
		interrupts = <18 IRQ_TYPE_LEVEL_LOW>;

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

			port@0 {
				reg = <0>;

				sii9022_in: endpoint {
					remote-endpoint = <&dpi_out>;
				};
			};

			port@1 {
				reg = <1>;

				sii9022_out: endpoint {
					remote-endpoint = <&hdmi_connector_in>;
				};
			};
		};
	};
};
