+
+Required properties:
+	- compatible: "sil,sii9022"
+	- reg: i2c address of the bridge
+
+Optional properties:
+	- interrupts-extended or interrupt-parent + interrupts: describe
+	  the interrupt line used to inform the host about hotplug events.
+	- reset-gpios: OF device-tree gpio specification for RST_N pin.
+
+Optional subnodes:
+	- video input: this subnode can contain a video input port node
+	  to connect the bridge to a display controller output (See this
+	  documentation [1]).
+

+Example:
+	hdmi-bridge@39 {
+		compatible = "sil,sii9022";
+		reg = <0x39>;
+		reset-gpios = <&pioA 1 0>;
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				reg = <0>;
+				bridge_in: endpoint {
+					remote-endpoint = <&dc_out>;
+				};
