As this is referring to the internal fifo (I think!) should we name it hwfifo_peak_mode_enable to separate it from being related to the software "buffer"? > + > +What: /sys/bus/iio/devices/iio:deviceX/activity_detect_event > +KernelVersion: > +Contact: linux-iio@xxxxxxxxxxxxxxx > +Description: > + adxl372 works in loop mode.

As you noted in the cover letter this is a bit odd having a mixture of an event and a more fundamental state control. Please state what value this will provide when read. > + > +What: /sys/bus/iio/devices/iio:deviceX/inactivity_detect_event > +KernelVersion: > +Contact: linux-iio@xxxxxxxxxxxxxxx > +Description: > + adxl372 works in loop mode.
