Sorry, I was going to reply to this, but having composed the reply,
and attempting to add the DT maintainers, mutt decided to completely
obliterate the To: line.

Please check with the DT maintainers what the expected behaviour is
supposed to be.

Does this mean the /cpus property is like a default for when a CPU node
doesn't specify the clock frequency, or does it mean that the /cpus
property should only exist when all the values for each CPU are
identical and thus the individual CPU node clock frequency should
not be specified.
