This series adds the possibility 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/rising_period
and thresh_falling_value/thresh_rising_value in events/ dir.
Set INT1 reg for activity/inactivity and push
event code in events fifo on irq.

2. Document use of iio events sysfs files.

1. Device FIFO can now be set in peak mode and only over the
threshold accelerations will be stored. Driver sets adxl372
FIFO in peak mode when the peak iio:trigger is selected.

Stefan Popa (1):
  iio: accel: adxl372: Add support for FIFO peak mode

  Changelog v3 -> v4:
  - add mutex for threshold write so that writing the two
  registers becomes atomic
  - added a trigger for peak mode, when selected in the trigger
  user interface, adxl372 will start recording only peak acceleration
  data in the fifo
  - added a adxl372.rst doc file explaining the use of iio events sysfs
