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."
