The question this raises is why that clock was missed the first time
around. I'd suggest whoever owns the clock driver can go through the
documentation again and look for others that may have been missed,
then send a patch to the driver to add *all* the missing ones for the
merge window, and one release later we add the driver depending on
previously unknown clocks.
