+SN65DSI86 DSI to eDP bridge chip
+--------------------------------
+
+This is the binding for Texas Instruments SN65DSI86 bridge.
+
+Required properties:
+- compatible: Must be "ti,sn65dsi86"
+- reg: i2c address of the chip, 0x2d as per datasheet
+- enable-gpios: OF device-tree gpio specifications for bridge_en pin
+
+- vccio-supply: A 1.8V supply that powers up the digital IOs.
+- vcca-supply: A 1.2V supply that powers up the analog circuits.
+
+Optional properties:
+
+- irq-gpios: OF device-tree gpio specification for interrupt pin
+
+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 DSI input
+- Video port 1 for eDP output
+
+Example
+-------
+
+edp-bridge at 2d {
+	compatible = "ti,sn65dsi86";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	reg = <0x2d>;
+
+	enable-gpios = <&msmgpio 33 GPIO_ACTIVE_HIGH>;
+
+	vccio-supply = <&pm8916_l17>;
+	vcca-supply = <&pm8916_l6>;
+
+	ports {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		port at 0 {
+			reg = <0>;
+
+			edp_bridge_in: endpoint {
+				remote-endpoint = <&dsi_out>;
+			};
+		};
+
+		port at 1 {
+			reg = <1>;
+
+			edp_bridge_out: endpoint {
+				remote-endpoint = <&edp_panel_in>;
+			};
+		};
+	};
