If it helps, I've prepared some branches on github that can be pulled
from tty-next (or pinctrl-next, or dropmachtimexh-fixup)
(I didn't find which branch to base this on in the AT91 tree)

the address is:
git at github.com:rgenoud/linux.git

branch for_upstream/gpiolib-helpers-for-tty-next has the gpiolib
series rebased onto tty-next
branch for_upstream/gpiolib-helpers-for-pinctrl-next : same thing on
pinctrl-next
branch for_upstream/gpiolib-helpers-for-dropmachtimexh-fixup : same on
dropmachtimexh-fixup
branch for_upstream/atmel_serial-final is just the series onto 3.14-rc6

I'm not sure this is the right way to do it though.

Richard.
