I am afraid I am unable to help you on this. I wasn't really pay
attention when usb-connector was introduced and not sure how it can
replace extcon. Now after read usb-connector.txt, it seems the binding
only defines a/b/c-connector, but not ab-connector, and there is no
enough information (at least for me) explaining how VBUS and ID fix into
this usb-connector binding.

Maybe Rob can provide some hint.
