+
+This binding is for display panels using an Ilitek ILI9341 controller in
+parallel mode.
+
+Required properties:
+- compatible:		"ronbo,mrb2801"
+- dc-gpios:		D/C pin
+- wr-gpios:		W/R pin
+- db-gpios:		8 or 16 DB pins
+- reset-gpios:		Reset pin
+- wr-up-down-delays:	Delays in ns for changing W/R from down to up and from up to down
+
+Optional properties:
+- backlight:	phandle of the backlight device attached to the panel
+- rotation:	panel rotation in degrees counter clockwise (0,90,180,270)
+
+Example:
