-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;
- };
