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

How many? Needs 'maxItems: 1'?

You can drop the description.

That's the default and we generally want this to be 'false'.

Hi, no it is other properties, these are the warnings:
arch/arm/boot/dts/s5pv210-goni.dt.yaml: tsp@4a: 'atmel,burst-length', 'atmel,orientation', 'atmel,threshold', 'atmel,x-line', 'atmel,x-size', 'atmel,y-line', 'atmel,y-size', 'vdd-supply' do not match any of the regexes: 'pinctrl-[0-9]+'

arch/arm/boot/dts/omap4-droid4-xt894.dt.yaml: touchscreen@4a: 'interrupt-names', 'wakeup-source' do not match any of the regexes: 'pinctrl-[0-9]+'

arch/arm/boot/dts/exynos5800-peach-pi.dt.yaml: trackpad@4b: 'wakeup-source' does not match any of the regexes: 'pinctrl-[0-9]+'
