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>;
|
|
};
