Hi,

it would be very good if you decided this now, before we add attributes.

The reason is that if this feature is needed for multiple subsystems,
the attribute should be added to the generic device structure, so that
the naming and semantics are consistent.
You really don't want to repeat this discussion for every subsystem.
