Cover letter [PATCH v1 0/2] iio-interrupt-trigger enhancements

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.
