Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6

Pull GPIO changes for v3.4 from Grant Likely:
 "Primarily gpio device driver changes with some minor side effects
  under arch/arm and arch/x86.  Also includes a few core changes such as
  explicitly supporting (electrical) open source and open drain outputs
  and some help for parsing gpio devicetree properties."

Fix up context conflict due to Laxman Dewangan adding sleep control for
the tps65910 driver separately for gpio's and regulators.
