Ilitek ILI9225 display panels

This binding is for display panels using an Ilitek ILI9225 controller in SPI
mode.

Required properties:
- compatible:	"vot,v220hf01a-t", "ilitek,ili9225"
- rs-gpios:	Register select signal
- 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)

Example:
	display@0{
		compatible = "vot,v220hf01a-t", "ilitek,ili9225";
		reg = <0>;
		spi-max-frequency = <12000000>;
		rs-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
		reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
		rotation = <270>;
	};
