Shouldn't this be something the core is implementing?  I'd strongly
expect that the clock drivers are relatively dumb and delegate all the
decision making to the core API.  Otherwise it's going to be hard for
the core to implement any logic that involves working with more than one
clock like rate change notification, or guarantee that driver requests
made through the API are satisfied, as the state of the clocks will be
changing underneath it.
