The way I see it, debugging facilities ideally would be somewhat
separate from rest of the driver. For example, imagine an on-device
gateway that lets you query the internal device state.
Sounds better than trying to tweak registers that other driver
parts might be tweaking at the same time, while trying to
take locks that other driver parts might be holding at the
same time.
