[PATCH v3 0/3] iio: mpl3115: support for events

[Antoni Pokusinski <apokusinski01@gmail.com>]

Hello,
The mpl3115 device can raise interrupts when a pressure or temperature
threshold is crossed, this patchset adds support for them using IIO's
events interface.

In this v3 I updated pressure data retrieval, so that the measurements
are now stored into u8[3], thanks for the explanation in v2. Some other
small cosmetic changes as well.

Kind regards,
Antoni Pokusinski

Changes since v2:
(general)
* added the patch tidying up the pressure data retrieval (u8[3] used)
(patch 2/3 "add threshold support")
* includes: removed unused linux/units.h
* read_thresh: fixed comment formatting
* interrupt_handler: val_press is now u8[3] instead of __be32 

Changes since v1:
(general)
* squashed the cleanup patch
* added the patch with the documentation update
(patch 1/2 "add threshold event support")
* patch description: explained changes in locking
* read_event_config: replaced switch with ifs
* read_event_config: return as early as possible, got rid of int_en_mask
* read/write_thresh: pressure: calculation changes to comply with raw ABI
* interrupt_handler: reordered the INT_SRC_* bits in if condition
* read/write_thresh: used sizeof() and values from limits.h
* write_thresh: replaced `u8 tmp[2]` with `__be16 tmp`
* dropped the space between casting `(u8 *) &tmp`
