    Subject[PATCH v4 2/5] dt-bindings: add binding for Sitronix ST7586 display panels
    Date
    This adds a new binding for Sitronix ST7586 display panels.

    Using lego as the vendor prefix in the compatible string because the display
    panel I am working with is an integral part of the LEGO MINDSTORMS EV3.

    v4 changes:
    * Dropped optional properties and only use pins actually used on LEGO EV3.
    * Rename dc to a0 since that is what is on the datasheet/LEGO schematic.

    +Sitronix ST7586 display panel
    +
    +Required properties:
    +- compatible: "lego,ev3-lcd".
    +- a0-gpios: The A0 signal (since this binding is for serial mode, this is
    + the pin labeled D1 on the controller, not the pin labeled A0)
    +- reset-gpios: Reset pin
    +
    +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)
    +
    +Example:
    + display@0{
    + compatible = "lego,ev3-lcd";
    + reg = <0>;
    + spi-max-frequency = <10000000>;
    + a0-gpios = <&gpio 43 GPIO_ACTIVE_HIGH>;
    + reset-gpios = <&gpio 80 GPIO_ACTIVE_HIGH>;
    + };
