Adding extcon driver for USB ID detection to dynamically

+EXTCON FOR DRA7xx

+Required Properties:
Please at lest explain what a DRA7xxx is, and the purpose of the HW
module this binding describes.
DRA7xx is the SoC name and the USB VID detection is implemented via gpio's
Basically it does only ID detection via GPIO and there is no VBUS
detection in h/w.
If there's no SoC-specific HW, then the binding has nothing to do with
the SoC; it's entirely generic.
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.
