Sitronix ST7735R display panels
|
|
|
|
This binding is for display panels using a Sitronix ST7735R controller in SPI
|
|
mode.
|
|
|
|
Required properties:
|
|
- compatible: "jianda,jd-t18003-t01", "sitronix,st7735r"
|
|
- dc-gpios: Display data/command selection (D/CX)
|
|
- reset-gpios: Reset signal (RSTX)
|
|
|
|
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:
|
|
|
|
backlight: backlight {
|
|
compatible = "gpio-backlight";
|
|
gpios = <&gpio 44 GPIO_ACTIVE_HIGH>;
|
|
}
|
|
|
|
...
|
|
|
|
display@0{
|
|
compatible = "jianda,jd-t18003-t01", "sitronix,st7735r";
|
|
reg = <0>;
|
|
spi-max-frequency = <32000000>;
|
|
dc-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;
|
|
reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;
|
|
rotation = <270>;
|
|
backlight = &backlight;
|
|
};
