Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6
Pull GPIO updates from Grant Likely:
"GPIO follow up patch and type change for v3.5 merge window
Primarily device driver additions, features and bug fixes. Not much
touching gpio common subsystem support. Should not be scary."
* tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (34 commits)
gpio: Provide the STMPE GPIO driver with its own IRQ Domain
