    +- 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:

    +- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
    +
    +Example:
    + mrb2801{
    + compatible = "ronbo,mrb2801";
    + db-gpios = <&gpio 17 0>, /* DB0 */

    + wr-gpios = <&gpio 20 0>; /* W/R */
    + wr-up-down-delays = <10 51>;
    + reset-gpios = <&gpio 21 0>; /* RST */
    + backlight = <&backlight>;
