dt-bindings: add binding for Sitronix ST7586 display panels 



This adds a new binding for Sitronix ST7586 display panels.

Using lego as the vendor prefix in the compatible string because the display
panel I am working with is an integral part of the LEGO MINDSTORMS EV3.

Sitronix ST7586 display panel



Required properties:

- compatible:	"lego,ev3-lcd".

- a0-gpios:	The A0 signal (since this binding is for serial mode, this is

                the pin labeled D1 on the controller, not the pin labeled A0)

- 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 = "lego,ev3-lcd";

		reg = <0>;

		spi-max-frequency = <10000000>;

		a0-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;

		reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;

	};
