First patch enable device-tree support. Second one adds poll(2) support through a new sysfs attribute file "count" showing how many times the attached interrupt occurred since trigger initialization. This allows a userspace process : * to explicitly wait for the interrupt to happen ; * and to know wether or not it missed interrupt events since last count retrieval. Regards.
