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

Pull GPIO driver changes from Grant Likely:
 "Lots of gpio changes, both to core code and drivers.

  Changes do touch architecture code to remove the need for separate
  arm/gpio.h includes in most architectures.

  Some new drivers are added, and a number of gpio drivers are converted
  to use irq_domains for gpio inputs used as interrupts.  Device tree
  support has been amended to allow multiple gpio_chips to use the same
  device tree node.

  Remaining changes are primarily bug fixes."
