Subject[PATCH] dt-bindings: input: atmel_mxt_ts: convert atmel,maxtouch.txt to yaml
Date
Convert the binding file atmel,maxtouch.txt to yaml format.
Also change the file name in the MAINTAINERS file.

This was tested and verified on ARM and ARM64 with:

make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/input/atmel,maxtouch.yaml
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/input/atmel,maxtouch.yaml

-Atmel maXTouch touchscreen/touchpad
-
-Required properties:
-- compatible:
- atmel,maxtouch
-
- The following compatibles have been used in various products but are
- deprecated:
- atmel,qt602240_ts
- atmel,atmel_mxt_ts
- atmel,atmel_mxt_tp
- atmel,mXT224
-
-- reg: The I2C address of the device
-
-- interrupts: The sink for the touchpad's IRQ output
- See ../interrupt-controller/interrupts.txt
-
-Optional properties for main touchpad device:
-
-- linux,gpio-keymap: When enabled, the SPT_GPIOPWN_T19 object sends messages
- on GPIO bit changes. An array of up to 8 entries can be provided
- indicating the Linux keycode mapped to each bit of the status byte,
- starting at the LSB. Linux keycodes are defined in
- <dt-bindings/input/input.h>.
-
- Note: the numbering of the GPIOs and the bit they start at varies between
- maXTouch devices. You must either refer to the documentation, or
- experiment to determine which bit corresponds to which input. Use
- KEY_RESERVED for unused padding values.
-
-- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)
-
-Example:
-
- touch@4b {
- compatible = "atmel,maxtouch";
- reg = <0x4b>;
- interrupt-parent = <&gpio>;
- interrupts = <TEGRA_GPIO(W, 3) IRQ_TYPE_LEVEL_LOW>;
- };
