-Rocktech jh057n00900 5.5" 720x1440 TFT LCD panel
-
-Required properties:
-- compatible: should be "rocktech,jh057n00900"
-- reg: DSI virtual channel of the peripheral
-- reset-gpios: panel reset gpio
-- backlight: phandle of the backlight device attached to the panel
-- vcc-supply: phandle of the regulator that provides the vcc supply voltage.
-- iovcc-supply: phandle of the regulator that provides the iovcc supply
-  voltage.

-Example:
-
-	&mipi_dsi {
-		panel@0 {
-			compatible = "rocktech,jh057n00900";
-			reg = <0>;
-			backlight = <&backlight>;
-			reset-gpios = <&gpio3 13 GPIO_ACTIVE_LOW>;
-			vcc-supply = <&reg_2v8_p>;
-			iovcc-supply = <&reg_1v8_p>;
-		};
