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
