+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@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@0 {
+ reg = <0>;
+
+ edp_bridge_in: endpoint {
+ remote-endpoint = <&dsi_out>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ edp_bridge_out: endpoint {
+ remote-endpoint = <&edp_panel_in>;
+ };
+ };
+ };
+}
