Use devm_delayed_work_autocancel() instead of hand writing it. This is
less verbose and saves a few lines of code.
devm_delayed_work_autocancel() uses devm_add_action() instead of
devm_add_action_or_reset(). This is fine, because if the underlying memory
allocation fails, no work has been scheduled yet. So there is nothing to

The ADXL367 is an ultralow power, 3-axis MEMS accelerometer.
The ADXL367 does not alias input signals to achieve ultralow power
consumption, it samples the full bandwidth of the sensor at all
data rates. Measurement ranges of +-2g, +-4g, and +-8g are available,
with a resolution of 0.25mg/LSB on the +-2 g range.
In addition to its ultralow power consumption, the ADXL367
has many features to enable true system level power reduction.
It includes a deep multimode output FIFO, a built-in micropower
temperature sensor, and an internal ADC for synchronous conversion
of an additional analog input.

Some accelerometers that support activity and inactivity
events also support a referenced mode, in which the
gravitational acceleration is taken as a point of
reference before comparing the acceleration to the
specified activity and inactivity magnitude.
For example, in the case of the ADXL367, for activity
detection, the formula is:
abs(acceleration - reference) > magnitude
Add a new event type that makes this behavior clear.

This is a rather unusual device (in IIO anyway). However, it has
a near to standard userspace ABI.
Note the work to move this out of staging was done against a minimal
QEMU model, which doesn't model all the features of the device.
I have no intention to upstream the QEMU model as it was developed
just to enable this driver cleanup.

This functionality is intended to allow for a few temperature
sensors to be missing (and hence not worth reading) on the final
device in a chain. The ones removed are 3 and 5 (unlike for
the ADC channels where it is 4 and 5).
The datasheet includes a foot note 3 to Table 12 that makes this complex
to support.
"(3) To remove AUX5 or AUX5 and AUX3 from the alert detection, conversions
on three auxiliary ADC input channels only must be selected in the
control register."
This mode has never been supported by the driver.
As this support would be complex to add and the rework is being done
against a QEMU model developed for the purposes of verifying nothing
is broken, it is better to drop this support for now.

This driver had a slightly non standard events ABI but there seems
to be no reason for not doing it with the core support for rising and
falling events on the two types of channels.
In theory the events on different daisy chained chips could be at
different levels, but the driver has never supported this and it doesn't
seem likely to be used so let us ignore that option.
Includes reordering so that we only set the software cached value
of the thresholds if the hardware write succeeds.

* pm_ptr() and RUNTIME_PM_OPS()/SYSTEM_SLEEP_PM_OPS
Make sure the functions are always visible to the compiler and removed by

This removes the need to mark the functions as __maybe_unused and saves
additional space with some build options as the dev_pm_ops structure
itself can be dropped automatically if CONFIG_PM is not enabled.

Removing instances of this approach from IIO also stops them being
copied into new drivers.
