This is looking pretty sane to me.

Grant, how do you prefer to handle this, since it spans of/dt, gpio
and tegra code? I can start a topic branch for Arnd to pull in for the
tegra parts, would you prefer picking up the of helper functions on
your own or is an ack from you and merge through the arm-soc tree
easier?
