This iio sysfs ABI defines a way to specify interrupt
persistence filter value for threshold based interrupts.
Example:
What: /sys/.../events/in_intensity0_thresh_persistence
What: /sys/.../events/in_proximity0_thresh_persistence
Currently, we don't have any way to specify the persistence
filter value in iio event framework. Many drivers use channel
ext info to work around this issue. This patch adds this option
to event info list.
Added IIO_EV_INFO_PERSISTENCE and corresponding string.
