V1->V2:
As suggested by Rob Herring:
* fixed $id: address
* added "hycon," in front of every custom property
* changed all possible property to boolean type
* removed proximity-sensor-switch property since it's not handled in driver
V2->V3:
As suggested by Jonathan Neuschäfer:
* fixed some typo
* fixed description indentation
* improved boolean properties descriptions
* improved hycon,report-speed description

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/input/touchscreen/hycon,hy46xx.example.dt.yaml:0:0: /example-0/i2c/hycon-hy4633@1c: failed to match any schema with compatible: ['hycon,hy4633']

See https://patchwork.ozlabs.org/patch/1461797

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

I've just send corrected patches.

Anyway I'd like to understand how to make dt_binding_check works correctly.

I've installed yamllint and 'make dt_binding_check' works but it still 
doesn't show that error up on compatible string.

yamllint I have is version 1.20.0

pip3 install dtschema --upgrade

I've already tried with that too and dtschema version is:
1.3.8

I've read that dtc must be compiled with YAML output enabled and it 
seems to be so, since when I issue 'make dt_binding_check' from my file:
hycon,hy46xx.yaml(with compatible string wrong "hycon,hy4633")

these files are generated:
hycon,hy46xx.example.dts

/dts-v1/;
/plugin/; // silence any missing phandle references


/{
     compatible = "foo";
     model = "foo";
     interrupt-parent = <&foo>;
     #address-cells = <1>;
     #size-cells = <1>;



     example-0 {
         #address-cells = <1>;
         #size-cells = <1>;

         #include <dt-bindings/gpio/gpio.h>
         #include <dt-bindings/interrupt-controller/arm-gic.h>
         i2c {
           #address-cells = <1>;
           #size-cells = <0>;
           hycon-hy4633@1c {
             compatible = "hycon,hy4633";
             reg = <0x1c>;
             interrupt-parent = <&gpio2>;
             interrupts = <5 IRQ_TYPE_EDGE_FALLING>;
             reset-gpios = <&gpio2 6 GPIO_ACTIVE_LOW>;
           };
         };

     };
};

...

So I can't reproduce the problem, can you point me some documentation 
that I didn't see before?

Thank in advance
Best regards
