I also wonder if exposing some of these knobs should be done in the
basic clock types.  Meaning that instead of having additional calls in
the clk.h API those calls could be exposed by the basic clock types that
map to the actions.

The question that needs to be answered is this: do generic drivers need
access to these additional functions (clk.h) or just the platform code
which implements some of the clock logic (basic clock types &
platform-speciic clock types).
