Subject[PATCH v1 1/2] dt-bindings: Add binding for Ilitek ILI9225 display panels
Date
This adds a new binding for display panels that use an Ilitek ILI9225
controller.

The "generic,2.2in-176x220-ili9225-tft" device listed has no identification
markings whatsoever and an hour of googling turned up nothing, hence the use
of "generic".

An example of this nameless device can be found at:
https://github.com/Nkawu/TFT_22_ILI9225

+Ilitek ILI9225 display panels
+
+This binding is for display panels using an Ilitek ILI9225 controller in SPI
+mode.
+
+Required properties:
+- compatible: "generic,2.2in-176x220-ili9225-tft"
+- rs-gpios: Register select signal
+- 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 = "generic,2.2in-176x220-ili9225-tft";
+ reg = <0>;
+ spi-max-frequency = <12000000>;
+ rs-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
+ reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
+ rotation = <270>;
+ };
