c486b70193 iio: proximity: sx9360: Add a new ACPI hardware ID 
From
https://treexy.com/products/driver-fusion/database/sensors/semtech/sx9360-proximity/

sx9360 SAR sensor can be presented with ACPI ID SAMM0208.

Whilst this does not appear to be an official ACPI ID, it is in the wild
(perhaps due to a typo on the SAM PnP ID).

5c682eeecf iio: proximity: sx9360: Switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() 
These new macros avoid the need for marking the callbacks __maybe_unused
whilst ensuring both callbacks and structure may be dropped by the compiler
if CONFIG_PM_SLEEP is not enabled.

19d32860dc iio: sx9360: fix iio event generation 
To convert SX9360 status register ["REG_STAT"], into a channel
index, we need to right shift by |stat_offset|, not left shift.
Also the PROXSTAT bit (3) is for channel 1 (PHM, Phase Measured), not (PHR,
Phase Reference, channel 0), so the offset is 2 instead of 3.
