Subject: [PATCH v2 0/2] iio: mpl3115: support for events

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.

The two previous patches were squashed, I also
added a small patch documenting the new pressure-event attributes.

Kind regards,
Antoni Pokusinski

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`
