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;

	};
