On one board I found that:
  probe of 5-0028 returned 1 after 259547 usecs

While some of this time is attributable to the pile of i2c transfers
that we do at probe time, the lion's share (over 200 ms) is sitting
waiting in the polling loop in sx9310_init_compensation() waiting for
the hardware to indicate that it's done.

There's no reason to block probe of all other devices on our probe.
Turn on async probe.

By default, if all three channels (x, y, z) are enabled, sample sets of
concurrent 3-axis data is stored in the FIFO. This patch adds the option
to configure the FIFO to store peak acceleration (x, y and z) of every
over-threshold event. When pushing to iio buffer we push only enabled
axis data.

Currently the driver configures adxl372 to work in loop mode.
The inactivity and activity timings  decide how fast the chip
will loop through the awake and waiting states and the
thresholds on x,y,z axis decide when activity or inactivity
will be detected.

This patch adds standard events sysfs entries for the inactivity
and activity timings: thresh_falling_period/thresh_rising_period
and for the in_accel_x_thresh_falling/rising_value.

For some time the market wants medical grade accuracy in medical range,
while still retaining the declared accuracy outside of the medical range
within the same sensor. That is why we created extended calibration
which is automatically switched to when object temperature is too high.

This patch also introduces the object_ambient_temperature variable which
is needed for more accurate calculation of the object infra-red
footprint as sensor's ambient temperature might be totally different
than what the ambient temperature is at object and that is why we can
have some more errors which can be eliminated. Currently this temperature
is fixed at 25, but the interface to adjust it by user (with external
sensor or just IR measurement of the other object which acts as ambient),
will be introduced in another commit.
