Subject: [PATCH v2 0/4] iio: pressure: hsc030pa: cleanup and triggered buffer

This set of patches covers the following:

 - small cleanup
 - mandatory 2ms delay between readings
 - support for triggered buffer readings

The support for devices that have "sleep mode" factory option that was
present in v1 of this patchset was removed, for a few reasons:

 - a Honeywell employee told me that this chip variant is extremely
    unlikely to be found in the wild, which also makes testing the
    driver functionality impossible
 - I found no reliable way of generating i2c/spi bus traffic with no
    payload (toggle CS for SPI case, send i2c packet containing only
    the address byte) that are required for the wakeup sequence.


Petre Rodan (4):
  dt-bindings: iio: pressure: honeywell,hsc030pa.yaml add spi props
  iio: pressure: hsc030pa cleanup
  iio: pressure: hsc030pa add mandatory delay
  iio: pressure: hsc030pa add triggered buffer
