Subject: [PATCH] dt-bindings: add binding for Sitronix ST7586 display panels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.

+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>;
+ };
