Ok, thanks for taking a look. Do you believe that the clock binding is any
closer to being finalized than the actual code implementing it? I think
it would be very helpful to at least put all the clock related settings
into the device tree in a way that is going to be stable, even if the
code is still in flux.

Moreover, if we have a binding document, we can start implementing code
for one platform and then generalize it later.
