Merge tag 'pinctrl-single-for-linus-for-v3.13-signed' into omap-for-v3.13/quirk

Changes to pinctrl-single to allow handling the wake-up
interrupts that most omaps have in each pinctrl register.

As I need these merged also into the omap tree, it was
agreed that I set them up into a separate branch for
both pinctrl tree and linux-omap tree to merge as needed.
