Hm.. as the description says:

8<--------------------------------------------------
gpios:
description: Array of one or more GPIO pins used to select the
regulator voltage/current listed in "states".
8<--------------------------------------------------

But we don't have a "states" property and we can't select between
voltage or current.

Marco
