Yes, it's fairly common to at least have hardware enable signals.  If
what was going on was actually understood by the driver in some way it
might be better but right now...  Especially in a series like this it's
really bad to just see loads of patches which boil down to "change the
semi-documented magic value" - this just makes the series depressing to
read.
