Kernel-4.18.0-80.el8_sitronix,st7735r

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;
};
