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." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in *_runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from *_runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...
