+The node for this driver must be a child node of a SPI controller, hence

+Optional properties:
+- dc-gpios: D/C pin. The presence/absence of this GPIO determines

+ - present: IM=x110 4-wire 8-bit data serial interface
+ - absent: IM=x101 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)
