+Driver for GE B850v3 LVDS/DP++ display bridge
+
+Required properties:
+  - compatible : should be "ge,b850v3-lvds-dp".
+  - reg : should contain the address used to ack the interrupts.
+  - interrupt-parent : phandle of the interrupt controller that services
+    interrupts to the device
+  - interrupts : one interrupt should be described here, as in
+    <0 IRQ_TYPE_LEVEL_HIGH>.
+  - edid-reg : should contain the address used to read edid information
+  - port : should describe the video signal connection between the host
+    and the bridge.
+
+Example:
+
+&mux2_i2c2 {
+	status = "okay";
+	clock-frequency = <100000>;
+
+	b850v3-lvds-dp-bridge@73  {
+		compatible = "ge,b850v3-lvds-dp";
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		reg = <0x73>;
+		interrupt-parent = <&gpio2>;
+		interrupts = <0 IRQ_TYPE_LEVEL_HIGH>;
+
+		edid-reg = <0x72>;
+
+		port {
+			b850v3_dp_bridge_in: endpoint {
+				remote-endpoint = <&lvds0_out>;
+			};
+		};
+	};
+};
