... which means a separate getrate() functions for every clock.  Not really
practical for PXA.

... which means a separate enable() function for each clock.  The delay
there has not a lot to do with the actual register you're frobbing, but
the resy of the SoC.  So, again, not really practical for PXA.

The result for PXA is a tradeoff between reducing the data size and
increasing the text size, or increasing the data size and keeping
the existing data size.
