Hi Prashant,

OK, that is good to know.  I haven't forgotten about this topic.  I'm
still trying to think of the best way to expose less-common operations
to drivers...

Based on Stephen's feedback in patch 0 I'll be waiting for another
version of this series before taking into clk-next.

Thanks,
Mike
