Ilitek ILI9341 display panels

This binding is for display panels using an Ilitek ILI9341 controller in SPI
mode.

Required properties:
- compatible:	"adafruit,yx240qv29", "ilitek,ili9341"
- dc-gpios:	D/C pin
- reset-gpios:	Reset pin

The node for this driver must be a child node of a SPI controller, hence
all mandatory properties described in ../spi/spi-bus.txt must be specified.

Optional properties:
- rotation:	panel rotation in degrees counter clockwise (0,90,180,270)
- backlight:	phandle of the backlight device attached to the panel

Example:
	display@0{
		compatible = "adafruit,yx240qv29", "ilitek,ili9341";
		reg = <0>;
		spi-max-frequency = <32000000>;
		dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
		rotation = <270>;
		backlight = <&backlight>;
	};
