Hi Rob,

I agree that these patches have seen enough time on the list.  I did
find one problem in testing: the high bank clock registration function
writes to clk_hb->hw.init which is marked const.  I fixed it up in the
below patch.  That fix is now squashed into into the final patch in your
series on the clk-next branch.  Let me know if you have any objections.

Regards,
Mike
