Items must be defined or just drop the property. How did it even appear?
Who asked for this? Your changelog is so vague that anything can happen
with this code and you will claim "it was review fix". No, you must
explain the changes.
Go back to previous review and implement all the changes requested.

That's not enable, but reset-gpios.

Drop. Do you see it anywhere in the bindings examples?

That's a duplicated patch... how many of this people are going to send?
Drop and rebase on top of previous work of people.
