A NULL clock is valid according to the clk.h api.  I would like to allow
parent to be NULL, resulting in a migration from the real clock tree to
the orphans list.

This feature was apparently buggy for some time and Rajagopal sent me a
patch off-list to fix it.  Rajagopal, can you post your patch publicly?

Thanks,
Mike
