I've done a few things recently.  Haavard Skinnemoen has got an
out-of-tree, avr32-specific gpio interface [1] which I first converted
to the generic gpio framework then completely re-wrote.  Both use
configfs but before either version could reach completion they were
obsoleted by David Brownell's gpio sysfs interface.

A version of my gpio-dev interface is attached.  Bear in mind it was
never completed, it's full of known bugs but hey, might be useful for
you anyway :-)

At the moment I'm experimenting with configfs for pinmux control on
AVR32 SoCs.  There's really nothing to see there yet, it's all just
dicking about atm.

np, will do :-)
