Jean-Baptiste ManeyrolandJonathan Cameron 82bd09ce4f iio: inv_sensors: improve period measurement by using a longer delay ...

Period measurement can be difficult when using high sampling
frequency where the jitter criteria is hard to meet because of the
system jitter.

This new version is using the delta time between 2 distant interrupts
to measure an interval of at least 20ms. 20ms is a good compromise
between the mitigation of system jitter and the delay to update
period. This way we decorrelate the period measurement from the
interrupt timestamps syncing using only the 2 last interrupts.
