Hello,
This set of patches adds support for the DRDY interrupt in the MPL3115
pressure sensor. The device has 2 interrupt lines, hence the new
binding. I also added support for the sampling frequency which
determines the time interval between subsequent measurements (in the
continuous measurements mode) so it's obiously tied to the DRDY
interrupt feature.
Kind regards,
Antoni Pokusinski

Changes since v1:
* P1: add `vdd-supply` and `vddio-supply`
* P2: new patch: use guards from cleanup.h
* P3: change macros of control register bits to convention
MPL3115_CTRLX_NAME
* P3: MPL3115_PT_DATA_EVENT_ALL: use GENMASK
* P3: trigger_probe: do not fail if dev_fwnode() returns NULL
* P3: trigger_probe: use devm_iio_trigger_register()
* P3: trigger_probe: introduced enum mpl3115_irq_type and
changed IRQ setup logic accordingly
* P4: MPL3115_CTRL2_ST: use GENMASK
* P4: read_raw: samp_freq: use FIELD_GET
* P4: write_raw: samp_freq: use FIELD_PREP
