       irq_shutdown
	   shut down the interrupt (defaults to ->disable if NULL)

       irq_enable
	   enable the interrupt (defaults to chip->unmask if NULL)

       irq_disable
	   disable the interrupt

       irq_ack
	   start of a new interrupt

       irq_mask
	   mask an interrupt source

       irq_mask_ack
	   ack and mask an interrupt source

       irq_unmask
	   unmask an interrupt source

       irq_eoi
	   end of interrupt

       irq_set_affinity
	   set the CPU affinity on SMP machines

       irq_retrigger
	   resend an IRQ to the CPU

       irq_set_type
	   set the flow type (IRQ_TYPE_LEVEL/etc.) of an IRQ

       irq_set_wake
	   enable/disable power-management wake-on of an IRQ

       irq_bus_lock
	   function to lock access to slow bus (i2c) chips

       irq_bus_sync_unlock

       irq_cpu_online
	   configure an interrupt source for a secondary CPU

       irq_cpu_offline
	   un-configure an interrupt source for a secondary CPU

       irq_suspend
	   function called from core code on suspend once per chip

       irq_resume
	   function called from core code on resume once per chip

       irq_pm_shutdown
	   function called from core code on shutdown once per chip
