So if the VPU depends on OCRAM the VPU should be enabling the OCRAM
clock.  The function of a given clock isn't terribly relevant, and
certainly grouping clocks together doesn't seem to be the obvious
solution from what you've said - if the driver doesn't know about the
clock it seems like the core ought to be enabling it transparently
rather than gluing it together with some other random clock.

Either way the point here is that individual drivers shouldn't be hand
coding this stuff, it should be being handled by core code.
