I don't understand why you need the driver core to initialize this one
type of thing? That should be in a driver, or in a class, or at worse
case, the platform code.

What makes clocks so "unique" here?

I suppose the issue here is that a lot of drivers currently use
clocks and a number of systems have badly setup default clock trees
at start time.

Mark Brown and others have argued that the management of clocks which
is common to all devices should not live in the driver.
