Could you summarize what is the issue with the binding?

At least for the case where we have one clock per CPU, the DT binding
is really dead simple: each CPU node can carry a "clocks" property, and
a "clock-latency" property. I really don't see why a long discussion is
needed to agree on such a binding.

Now, if the DT binding problem is related to those cases where you have
siblings, i.e one clock controlling *some* of the CPUs, but not all
CPUs or just one CPU, then maybe we could leave this aside for now,
only support the following cases:

 * One clock for all CPUs
 * One clock for each CPU

Thanks,

Thomas
