-Orise Tech OTM8009A 3.97" 480x800 TFT LCD panel (MIPI-DSI video mode)
-
-The Orise Tech OTM8009A is a 3.97" 480x800 TFT LCD panel connected using
-a MIPI-DSI video interface. Its backlight is managed through the DSI link.
-
-Required properties:
-  - compatible: "orisetech,otm8009a"
-  - 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.
-
-Example:
-&dsi {
-	...
-	panel@0 {
-		compatible = "orisetech,otm8009a";
-		reg = <0>;
-		reset-gpios = <&gpioh 7 GPIO_ACTIVE_LOW>;
-		power-supply = <&v1v8>;
-	};
-};
