This adds a new binding for Ilitek ILI9341 display panels. It includes a compatible string for one display (more can be added in the future). The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout board[2] and in Mindsensors' PiStorms[3]. The vendor prefix "adafruit" is used because the actual vendor is not known, but Adafruit is the most common source for a product that contains this panel.

Ilitek ILI9341 display panels
|
|
|
|
This binding is for display panels using an Ilitek ILI9341 controller in SPI
|
|
mode.
|
|
|
|
Required properties:
|
|
- compatible: "adafruit,yx240qv29", "ilitek,ili9341"
|
|
- dc-gpios: D/C pin
|
|
- reset-gpios: Reset pin
|
|
|
|
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:
|
|
- rotation: panel rotation in degrees counter clockwise (0,90,180,270)
|
|
- backlight: phandle of the backlight device attached to the panel
|
|
|
|
Example:
|
|
display@0{
|
|
compatible = "adafruit,yx240qv29", "ilitek,ili9341";
|
|
reg = <0>;
|
|
spi-max-frequency = <32000000>;
|
|
dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
|
|
reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
|
|
rotation = <270>;
|
|
backlight = <&backlight>;
|
|
};
