This adds a new binding for Ilitek ILI9341 display panels. It includes
a compatible string for one display (more can be added in the future).

The vendor prefix "noname" is used because the vendor is not known.
The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout
board[2] and in Mindsensors' PiStorms[3].

Looks like I forgot to update "noname" to "adafruit" in the commit message.
Patch is as intended though.

+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>;
