+
+This binding is for display panels using an Ilitek ILI9341 controller in

+- 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:
+ mrb2801{
+ compatible = "ronbo,mrb2801";
+ db-gpios = <&gpio 17 0>, /* DB0 */
