Subject: [PATCH v4 0/3] add support for Sensirion SPS30 PM sensor

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

v4:
 * this will likely go in next release cycle so increase version to 4.22
 * use KBUILD_MODNAME in format specifier

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

Tomasz Duszynski (3):
  iio: add IIO_MASSCONCENTRATION channel type
  iio: chemical: add support for Sensirion SPS30 sensor
  iio: chemical: sps30: add device tree support
