Subject: [PATCH] dt-bindings: input: atmel_mxt_ts: convert atmel,maxtouch.txt to yaml
Date:   Tue,  3 Mar 2020 19:25:33 +0200
Message-Id: <20200303172533.30602-1-dafna.hirschfeld@collabora.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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>;
-	};
