I think I remember reading somewhere that the target of the common clock 
framework was to prevent every SoC from introducing their own special clock 
types and instead  create these structures from separate clocks (mux clk + 
gate clk) and not to have every SoC create their own custom clock types.

The Samsung clock drivers at the moment follow this paradigm of combining the 
existing "simple" clocks and only introduce new clock types for the pll 
clocks, that really need special handling.

So it would probably good to keep it this way and define your clocks from 
their individual components, as all the other Samsung clocks currently do.
