Do we have any code to use this?

Normally that shouldn't matter, but we already an unused binding for
this. :-)

Please provide rationale for doing it this way.  Ideally it should
probably use whatever http://devicetree.org/ClockBindings ends up being.

OK, I see the code now.  Still could use some explanation.
