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
