Humm, interesting. Currently we support OLPC and CE4100 for x86 DT based 
systems. Adding a new platform implies numerous new bindings yet there 
is only 1 here. I'm guessing your DT is generated by the hypervisor, but 
an example would be nice to see and run thru dtschema validation. We've 
unfortunately been trying to fix KVM/QEMU DT years after it was created.

Bindings come before using them...
