[PATCH v4 0/3] iio: mpl3115: support for events

[Antoni Pokusinski]

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 v4 mostly some minor variable rename changes and a comment in
read_info_raw according to the review in v3.

Kind regards,
Antoni Pokusinski

Changes since v3:
(patch 1/3 "use get_unaligned_be24() to retrieve pressure data")
* commit msg: "get_unaligned_be24" -> "get_unaligned_be24()"
* read_info_raw: renamed "tmp[3]" -> "press_be24[3]"
* read_info_raw: added comment at pressure val computation
(patch 2/3 "add threshold support")
* interrupt_handler: added sizeof() in a i2c_read_i2c_block call
* read_thresh: renamed "tmp" -> "press_tgt"
* write_thresh: renamed "tmp" -> "press_tgt"

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`
