[v2,0/6] iio: accel: adxl372: add peak mode

Message

Alexandru Tachici Feb. 25, 2020, 12:09 p.m. UTC

This series adds the posibility to configure
the device, from sysfs, to work in peak mode. This enables
adxl372 to capture only over threshold accelerations.

1. Create sysfs files for falling_period and rising_period
in events/ dir.

2. Create sysfs files for thresh_falling_value and
thresh_rising_value for each axis.

3. Set INT1 reg for acitivity/inactivity and push
event code in events fifo on irq.

4. Add additional ABIs in order to explain the
user that setting values in the events/ sysfs files
also changes device behaviour.

5. Update sysfs docs: renames, added two new
entries for the activity_detect_event/
inactivity_detect_event

  iio: accel: adxl372: Add support for FIFO peak mode

1. Device FIFO can now be set in peak mode and only over the
threshold accelerations will be stored.

Changelog V1 -> V2:
- switched from custom sysfs for setting the accel thres/timings
to standard events interface.
- renamed fifo_peak_mode_enable to buffer_peak_mode_enable
- on activity/inactivity, event codes are now pushed in
the events FIFO
- added additional custom sysfs for explaining that setting
values in the events/ sysfs files will change the device's
behaviour.
