Subject: [PATCH 2/3] dt-bindings: new binding for Ilitek ILI9341 display panels
Date: Mon, 14 May 2018 20:43:48 -0500 [thread overview]
Message-ID: <20180515014349.26226-3-david@lechnology.com> (raw)
In-Reply-To: <20180515014349.26226-1-david@lechnology.com>
This adds a new binding for Ilitek ILI9341 display panels. It includes
a compatible string for one display (more can be added in the future).
The vendor prefix "noname" is used because the vendor is not known.
The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout
board[2] and in Mindsensors' PiStorms[3].

+Ilitek ILI9341 display panels
+
+This binding is for display panels using an Ilitek ILI9341 controller in SPI
+mode.
+
+Required properties:
+- compatible: "noname,yx240qv29", "ilitek,ili9341"
+- dc-gpios: D/C pin
+- 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)
+- backlight: phandle of the backlight device attached to the panel
+
+Example:
+ display@0{
+ compatible = "noname,yx240qv29", "ilitek,ili9341";
+ reg = <0>;
+ spi-max-frequency = <32000000>;
+ dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
