Yes, that might be required.  I guess ideally we could get constraints
through the clock framework or cpufreq would be a real platform device
and take platform data.  Some of it should fall out of restricting the
voltages that can be selected.

OK, I'll do so next time I respin - probably after -rc1 (which I expect
will be next week some time).
