+Raydium RM67171 OLED LCD panel with MIPI-DSI protocol
+
+Required properties:
+- compatible: 		"raydium,rm67191"
+- reg:			virtual channel for MIPI-DSI protocol
+			must be <0>
+- dsi-lanes:		number of DSI lanes to be used
+			must be <3> or <4>
+- port: 		input port node with endpoint definition as
+			defined in Documentation/devicetree/bindings/graph.txt;
+			the input port should be connected to a MIPI-DSI device
+			driver
+
+Optional properties:
+- reset-gpio:		a GPIO spec for the RST_B GPIO pin
+- pinctrl-0		phandle to the pin settings for the reset pin
+- width-mm:		physical panel width [mm]
+- height-mm:		physical panel height [mm]
+- display-timings:	timings for the connected panel according to [1]
+- video-mode:		0 - burst-mode
+			1 - non-burst with sync event
+			2 - non-burst with sync pulse
+
+[1]: Documentation/devicetree/bindings/display/display-timing.txt
+
+Example:
+
+	panel@0 {
+		compatible = "raydium,rm67191";
+		reg = <0>;
+		pinctrl-0 = <&pinctrl_mipi_dsi_0_1_en>;
+		reset-gpio = <&gpio1 7 GPIO_ACTIVE_HIGH>;
+		dsi-lanes = <4>;
+		width-mm = <68>;
+		height-mm = <121>;
+
+		port {
+			panel_in: endpoint {
+				remote-endpoint = <&mipi_out>;
+			};
+		};
+	};
