Merge branch 'gpio/next' of git://git.secretlab.ca/git/linux-2.6
* 'gpio/next' of git://git.secretlab.ca/git/linux-2.6: h8300: Move gpio.h to gpio-internal.h gpio: pl061: add DT binding support gpio: fix build error in include/asm-generic/gpio.h gpiolib: Ensure struct gpio is always defined irq: Add EXPORT_SYMBOL_GPL to function of irq generic-chip gpio-ml-ioh: Use NUMA_NO_NODE not GFP_KERNEL gpio-pch: Use NUMA_NO_NODE not GFP_KERNEL gpio: langwell: ensure alternate function is cleared gpio-pch: Support interrupt function gpio-pch: Save register value in suspend() gpio-pch: modify gpio_nums and mask gpio-pch: support ML7223 IOH n-Bus gpio-pch: add spinlock in suspend/resume processing gpio-pch: Delete invalid "restore" code in suspend() gpio-ml-ioh: Fix suspend/resume issue gpio-ml-ioh: Support interrupt function gpio-ml-ioh: Delete unnecessary code gpio/mxc: add chained_irq_enter/exit() to mx3_gpio_irq_handler() gpio/nomadik: use genirq core to track enablement gpio/nomadik: disable clocks when unused
