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".
+
+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:
+- dc-gpios:    D/C pin. The presence/absence of this GPIO determines
+               the panel interface operation mode (IF[3:1] pins):
+               - present: IF=011 4-wire 8-bit data serial interface
+               - absent:  IF=010 3-wire 9-bit data serial interface
+- reset-gpios: Reset pin
+- power-supply:        A regulator node for the supply voltage.
+- backlight:   phandle of the backlight device attached to the panel
+- rotation:    panel rotation in degrees counter clockwise (0,90,180,270)
+
+Example:
+       display@0{
+               compatible = "lego,ev3-lcd";
+               reg = <0>;
+               spi-max-frequency = <10000000>;
+               dc-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;
+               reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;
+       };
