+Analog Device ADV7123 Video DAC
+-------------------------------
+
+The ADV7123 is a digital-to-analog converter that outputs VGA signals from a
+parallel video input.
+
+Required properties:
+
+- compatible: Should be "adi,adv7123"
+
+Optional properties:
+
+- psave-gpios: Power save control GPIO
+
+Required nodes:
+
+The ADV7123 has two video ports. Their connections are modeled using the OF
+graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 for DPI input
+- Video port 1 for VGA output
+
+
+Example
+-------
+
+ adv7123: encoder@0 {
+ compatible = "adi,adv7123";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ adv7123_in: endpoint@0 {
+ remote-endpoint = <&dpi_out>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ adv7123_out: endpoint@0 {
+ remote-endpoint = <&vga_connector_in>;
+ };
+ };
+ };
+ };
