I am currently working on adding device tree support to the extcon-gpio driver.

Wonder if it would make sense to just use that driver. As far as I can see
the only missing part is support for multiple cables and cable naming through
device tree properties.

Any thoughts ? The patches are not yet clean enough to submit upstream,
but I could send them as RFC if there is interest.
