Merge tag 'integrator-for-v3.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/soc

Merge "single Integrator patch" from Linus Walleij:

This sets up the dynamically detected IM-PD1 GPIO lines
by way of GPIO descriptors, avoiding any use of the GPIO
global numberspace.
