+Multi-Inno MI0283QT display panel
+
+Required properties:
+- compatible:  "multi-inno,mi0283qt".
+
+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 mode (IM[3:0] pins):
+               - 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)
+
+Example:
+       mi0283qt@0{
+               compatible = "multi-inno,mi0283qt";
+               reg = <0>;
+               spi-max-frequency = <32000000>;
+               rotation = <90>;
+               dc-gpios = <&gpio 25 0>;
+               backlight = <&backlight>;
+       };
