iio: accel: add ADXL367 driver

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.

iio: ABI: add note about configuring other attributes during buffer capture

It might be impossible to configure other attributes (e.g.: events, scale,
sampling rate) if they impact the currently active buffer capture session.

On ADXL367, writing to register before 0x2E requires the device to be
placed in standby mode, otherwise the changes might be effective for
only part of a measurement.

To ensure this requirement, the configuration attributes of the IIO
device try to claim direct mode before switching to standby mode.
During a buffer capture, direct mode cannot be claimed, and the
attribute write callback returns -EBUSY.

Describe this behavior in the buffer/enable attribute description.

iio: ABI: document mag_referenced

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.

staging:iio:adc:ad7280a: Drop buggy support for early termination of AUX alert.

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).

"(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

This mode has never been supported by the driver.

iio:temperature:mlx90614: Switch from CONFIG_PM* guards to pm_ptr() etc

Letting the compiler remove these functions when the kernel is built
without one or  more of CONFIG_PM/CONFIG_PM_SLEEP support is simpler and
less error prone than the use of #ifdef based config guards.
