Stacey Sheldon bfe6676eed exti: rewrite exti layer to improve portability ... The exti layer now allows drivers to register interrupt callbacks during board initialization. All details of the driver using a particular EXTI pin have been removed from the EXTI layer so it can now be used on any board without board-specific modification. This includes some nice refinements provided by Mike Smith during initial review. His original commits have been squashed into this one.		2012-01-22 23:23:41 -05:00
