To sucessfully probe some devices their corresponding PM domains may
need to be powered.

Isn't that what pm_runtime_get*() is supposed to be doing?  Why isn't
that working?

Also, I do not understand why we placing device into a power domain only
when we probe it. Why if I unbind device from its driver (or do not have
a driver for it) it disappears from its power domain? To me power domain
and having driver bound to a device are 2 orthogonal concepts.

That's a different discussion, I don't think we want to go there
within this context.

Kind regards
