  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
