I wonder why one cares about ID/VBUS detection if the port doesn't
operate in OTG mode?

I assume the "extcon" property is already fully documented in the
binding for the USB controller? For some reason, "extcon" looks like an
odd property name; I would have expected something more HW-oriented that
Linux-subsystem-oriented, such as "connector", or "usb-connector".
