-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>;

-               dsi-lanes = <4>;
-               width-mm = <68>;
-               height-mm = <121>;
-
-               port {
-                       panel_in: endpoint {
