+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-gpios:         a GPIO spec for the RST_B GPIO pin
+- v3p3-supply:         phandle to 3.3V regulator that powers the VDD_3V3 pin
+- v1p8-supply:         phandle to 1.8V regulator that powers the VDD_1V8 pin
+- width-mm:            see panel-common.txt
+- height-mm:           see panel-common.txt
+- video-mode:          0 - burst-mode
+                       1 - non-burst with sync event
+                       2 - non-burst with sync pulse
+
+Example:
+
+       panel@0 {
+               compatible = "raydium,rm67191";
+               reg = <0>;
+               pinctrl-0 = <&pinctrl_mipi_dsi_0_1_en>;
+               pinctrl-names = "default";
+               reset-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>;
+               dsi-lanes = <4>;
+               width-mm = <68>;
+               height-mm = <121>;
+
+               port {
+                       panel_in: endpoint {
+                               remote-endpoint = <&mipi_out>;
+                       };
+               };
+       };
