    +Sitronix ST7735R display panels
    +
    +This binding is for display panels using a Sitronix ST7735R controller in SPI
    +mode.
    +
    +Required properties:
    +- compatible: "sitronix,st7735r-jd-t18003-t01"
    +- 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 = "sitronix,st7735r-jd-t18003-t01";
    + reg = <0>;
    + spi-max-frequency = <32000000>;
    + dc-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;
    + reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;
    + rotation = <270>;
    + backlight = &backlight;
    + };
