From: Tomasz Duszynski
Date: Wed Dec 12 2018 - 13:30:42 EST


This patch series adds support for Sensirion SPS30 particulate matter
sensor. Along with a driver itself, new channel type and modifiers
for distinguishing between coarse and fine particles measurements are
introduced.

Sensor datasheet can be downloaded from

https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/0_Datasheets/Particulate_Matter/Sensirion_PM_Sensors_SPS30_Datasheet.pdf

v3:
* convert be32 to cpu using predefined macro
* remove semicolon: reported by semicolon.cocci
* use capitalization consistently (particulate matter)

v2:
* add support for PM1 and PM4 measurements
* get rid of variable length arrays
* do proper cleanup via devm_add_action_or_reset()
* add extra level of precision (two decimal places) while displaying
measurements
* improve comments a little bit
* slight refactoring and general improvements here and there
