+THS8135 Video DAC
+-----------------
+
+This is the binding for Texas Instruments THS8135 Video DAC bridge.
+
+Required properties:
+
+- compatible: Must be "ti,ths8135"
+
+Required nodes:
+
+This device has two video ports. Their connections are modelled using the OF
+graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 for RGB input
+- Video port 1 for VGA output
+
+Example
+-------
+
+vga-bridge {
+ compatible = "ti,ths8135";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+
+ vga_bridge_in: endpoint {
+ remote-endpoint = <&lcdc_out_vga>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ vga_bridge_out: endpoint {
+ remote-endpoint = <&vga_con_in>;
