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.

  iio: accel: adxl372: Add additional trigger ABI docs

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

Changelog v4 -> v5:
  - squash iio event interface patch into peak mode patch
  - move patch to 100 lines length
  - use((x) & BIT(0)) construct for define ADXL372_Y_AXIS_EN(x)
  - add ABI docs to explain the use of the additional trigger
