I didn't Cc him because you missed him, but because we have been
discussing opp-v2 bindings recently and this was somehow related to
that. :)

I don't know, but it seems obvious to me: Bindings first and then the
code.

Not really, but I got a bit confused now with your reply.

So, what I meant when I wrote: "Nodes for virtual devices aren't
allowed in DT", was that we aren't supposed to do something like:

cpufreq {
 ...
}

in DT as cpufreq isn't a device here. A CPU is a device and that can
contain whatever property we feel is reasonable.

What SPEAr and Exyons did was putting something in the cpu-node. Not a
node for cpufreq device itself. Couldn't find HREF and snowball's
bindings though..
