Subject: Re: [PATCH v7 1/1] iio/scmi: Adding support for IIO SCMI Based
 Sensors

Hi

I reposted my series on top of the take3 immutable branch from Jonathan
at:

https://lore.kernel.org/lkml/20210316124903.35011-1-cristian.marussi@arm.com/T/#t

You should have received an email regarding the relevant IIO SCMI patch

v7-0025-iio-scmi-port-driver-to-the-new-scmi_sensor_proto.patch

which includes the port of your v7 IIO SCMI driver to the new API, and moved
also the notification registration to the probe phase to simplify it
further.

On my side I tested with some fake emulated sensors emitting periodic
100ms SENSOR_UPDATE notifs...and verifying that notifications are still
dispatched and received fine. (values are just fakes)

If you can have a look, comment and possibly Ack.

Thanks

Cristian
