    1 Multi-Inno MI0283QT display panel
    2 
    3 Required properties:
    4 - compatible:   "multi-inno,mi0283qt".
    5 
    6 The node for this driver must be a child node of a SPI controller, hence
    7 all mandatory properties described in ../spi/spi-bus.txt must be specified.
    8 
    9 Optional properties:
   10 - dc-gpios:     D/C pin. The presence/absence of this GPIO determines
   11                 the panel interface mode (IM[3:0] pins):
   12                 - present: IM=x110 4-wire 8-bit data serial interface
   13                 - absent:  IM=x101 3-wire 9-bit data serial interface
   14 - reset-gpios:  Reset pin
   15 - power-supply: A regulator node for the supply voltage.
   16 - backlight:    phandle of the backlight device attached to the panel
   17 - rotation:     panel rotation in degrees counter clockwise (0,90,180,270)
   18 
   19 Example:
   20         mi0283qt@0{
   21                 compatible = "multi-inno,mi0283qt";
   22                 reg = <0>;
   23                 spi-max-frequency = <32000000>;
   24                 rotation = <90>;
   25                 dc-gpios = <&gpio 25 0>;
   26                 backlight = <&backlight>;
   27         };
