Thanks for the feedback! Few questions below.

Do you think it is worth to have both of the drivers in parallel for a
period until
we figure out that everything is correct? The IIO config symbol can be enabled
only hwmon symbol is not enabled?

That's a good point. Anyhow, there is no single instance of regmap_get_device
in the IIO tree. I counted at least 4 drivers where we could use it.
Do you think
is there a great benefit from using it?

This will be a nice change for Linux kernel outreachy applicants :).
I'm sure they will
love to work on it.

The rest should be for the timestamp and I will fix it :).

thanks,
