4166b47c2b iio:light: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.

e12ffd241c iio: light: rpr0521 triggered buffer
Set up and use triggered buffer if there is irq defined for device in
device tree. Trigger producer triggers from rpr0521 drdy interrupt line.
Trigger consumer reads rpr0521 data to scan buffer.
Depends on previous commits of _scale and _offset.

9ece370b02 iio: light: rpr0521 channel numbers reordered
Move proximity channel from last to first in structs to avoid confusion
later with buffered triggers. Proximity data output is first in rpr0521
register map.

734c442303 iio: light: rpr0521 proximity offset read/write
Add sysfs read/write proximity offset feature. Offset is read/write from
sensor registers. Values are proximity raw 10-bit values. After applying
offset value, output values will be (measured_raw - offset_value). Output
values are unsigned so offset value doesn't make output negative.

484c314b90 iio: light: rpr0521 on-off sequence change for CONFIG_PM
Refactor _set_power_state(), _resume() and _suspend().
Enable measurement only when needed, not in _init(). System can suspend
during measurement and measurement is continued on resume.
Pm turns off measurement when both ps and als measurements are disabled for
2 seconds. During off-time the power save is 20-500mA, typically 180mA.

12d7494913 iio: light: rpr0521 poweroff for probe fails
Set sensor measurement off after probe fail in pm_runtime_set_active() or
iio_device_register(). Without this change sensor measurement stays on
even though probe fails on these calls.

This is maybe rare case, but causes constant power drain without any
benefits when it happens. Power drain is 20-500uA, typically 180uA.

7d0ead5c3f iio: Reconcile operation order between iio_register/unregister and pm functions
At probe, runtime pm should be setup before registering the sysfs interface so
that all the power attributes are accurate and functional when registering.
Also, when removing the device we should unregister first to make sure
that the interfaces that may result in wakeups are no longer available.

Fix this behaviour for the following drivers: bmc150, bmg160, kmx61,
kxcj-1013, mma9551, mma9553, rpr0521.
