> Number of clocks supported by Linux drivers might vary - sometimes we add
> new clocks, not exposed previously.  Therefore this number of clocks
should
> not be in the bindings, because otherwise we should not change it.
> 
> Define number of clocks per each clock controller inside the driver
directly.
