git grep -C 3 connector:

We got a lot to review thus we make reviews concise. I understand that
it might lead to insufficient guidance, so more help in removing
workload from maintainers is always appreciated.

Instead of using vulgar words towards us, please put a bit more effort
and look at other recent bindings how they do it.

Review is provided in good faith and if it is by any chance incorrect,
it is enough to disagree instead of throwing things like above. That's
not acceptable.

richtek,usb-connector is not the good example here. Your previous code here:
https://lore.kernel.org/all/20250225090014.59067-2-clamor95@xxxxxxxxx/

looks correct - you have there port. So where does charger_input point?

Bindings are used by other projects as well and they live here because
of possibility of review by skilled people and due to size of the
community. It does not make them, in general, Linux specific.

We didn't. They are described.

There is no such thing as "extcon" from hardware point of view. Point us
to any standard or even wikipedia article describing it.
