I think it would be better not to merge this driver until the user interface
in the extcon framework has been finalized. I don't mind the driver, but I
want to prevent user interfaces from appearing in the kernel that we
intend to change anyway.

How about dropping the driver from the mfd tree, and adding it into the
extcon series for the next posting?
