+TC358764 MIPI-DSI to LVDS panel bridge
+
+Required properties:
+  - compatible: "toshiba,tc358764"
+  - reg: the virtual channel number of a DSI peripheral
+  - vddc-supply: core voltage supply
+  - vddio-supply: I/O voltage supply
+  - vddmipi-supply: MIPI voltage supply
+  - vddlvds133-supply: LVDS1 3.3V voltage supply
+  - vddlvds112-supply: LVDS1 1.2V voltage supply
+  - reset-gpios: a GPIO spec for the reset pin
+
+The device node can contain zero to two 'port' child nodes, each with one
+child
+'endpoint' node, according to the bindings defined in [1].
+The following are properties specific to those nodes.
+
+port:
+  - reg: (required) can be 0 for DSI port or 1 for LVDS port;
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt
+
+Example:
+
+	bridge@0 {
+		reg = <0>;
+		compatible = "toshiba,tc358764";
+		vddc-supply = <&vcc_1v2_reg>;
+		vddio-supply = <&vcc_1v8_reg>;
+		vddmipi-supply = <&vcc_1v2_reg>;
+		vddlvds133-supply = <&vcc_3v3_reg>;
+		vddlvds112-supply = <&vcc_1v2_reg>;
+		reset-gpios = <&gpd1 6 GPIO_ACTIVE_LOW>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		port@1 {
+			reg = <1>;
+			lvds_ep: endpoint {
+				remote-endpoint = <&panel_ep>;
+			};
+		};
+	};
