-Raydium Semiconductor Corporation RM68200 5.5" 720p MIPI-DSI TFT LCD panel
-
-The Raydium Semiconductor Corporation RM68200 is a 5.5" 720x1280 TFT LCD
-panel connected using a MIPI-DSI video interface.
-
-Required properties:
-  - compatible: "raydium,rm68200"
-  - reg: the virtual channel number of a DSI peripheral
-
-Optional properties:
-  - reset-gpios: a GPIO spec for the reset pin (active low).
-  - power-supply: phandle of the regulator that provides the supply voltage.
-  - backlight: phandle of the backlight device attached to the panel.
-
-Example:
-&dsi {
-	...
-	panel@0 {
-		compatible = "raydium,rm68200";
-		reg = <0>;
-		reset-gpios = <&gpiof 15 GPIO_ACTIVE_LOW>;
-		power-supply = <&v1v8>;
-		backlight = <&pwm_backlight>;
-	};
