1. Use subject prefixes matching the subsystem (git log --oneline -- ...).

2. Anyway that's not correct subject. Look at existing commits.

3. Run spell check.

4. Missing full stop.

Filename with vendor prefix, just like compatible.

Drop quotes from both.

That's not a correct (real) compatible. Drop.

Drop description.

Missing blank line.

Nope, use existing property. See gpio-consumer-common

This does not work like that. You did not even test it, right?

No clue what's this. You need to explain in details in description.

Ditto and in all other places.

I have no clue what is gloabel mode but the field looks incorrect. Drop
or properly describe.

Also wrong line wrapping.

No. Use interrupts.

Does not look like you tested the bindings. Please run `make
dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
