Subject: [PATCH 0/9] st_lsm6dsx: add tap event detection

The bulk of this patch set consists of reworking the existing code for event
detection (which supports IIO_EV_TYPE_THRESH events only) in order to make it
generic to accommodate different event types. Actual support for tap events is
implemented in the last patch.
Tested on LSMDSV16X.

Francesco Lavra (9):
  iio: imu: st_lsm6dsx: dynamically initialize iio_chan_spec data
  iio: imu: st_lsm6dsx: make event_settings more generic
  iio: imu: st_lsm6dsx: move wakeup event enable mask to event_src
  iio: imu: st_lsm6dsx: dynamically allocate iio_event_spec structs
  iio: imu: st_lsm6dsx: rework code to check for enabled events
  iio: imu: st_lsm6dsx: remove event_threshold field from hw struct
  iio: imu: st_lsm6dsx: make event management functions generic
  iio: imu: st_lsm6dsx: add event configurability on a per axis basis
  iio: imu: stm_lsm6dsx: add tap event detection
