[PATCH 01/14] dt-bindings: display: convert ilitek,ili9341.txt to dt-schema

Conor Dooley mail at conchuod.ie

From: Conor Dooley <conor.dooley at microchip.com>

A dt-schema binding for the Ilitek ili9341 was created as
panel/ilitek,ili9341.yaml but the txt binding was ignored in the
process. Move the remaining items in the txt binding to the yaml one &
delete it.

The example in the txt binding has a spi-max-frequency which disagrees
with the yaml replacement (and its own documentation) so change that to
conform with the binding. There are no users in tree of the Adafruit
yx240qv29 to check against.

-Ilitek ILI9341 display panels
-
-This binding is for display panels using an Ilitek ILI9341 controller in SPI
-mode.
-
-Required properties:
-- compatible:	"adafruit,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 at 0{
-		compatible = "adafruit,yx240qv29", "ilitek,ili9341";
-		reg = <0>;
-		spi-max-frequency = <32000000>;
-		dc-gpios = <&gpio0 9 GPIO_ACTIVE_HIGH>;
-		reset-gpios = <&gpio0 8 GPIO_ACTIVE_HIGH>;
-		rotation = <270>;
-		backlight = <&backlight>;
-	};
