Be more specific in the model property. What is the full (human
readable) name of this board? Since your using this simply as a
template, it may be better to just omit this property entirely.

All of the new compatible values in this file need to be documented in
Documentation/devicetree/bindings.

Drop 'device_type' property. It only makes sense if you have a real
OpenFirmware implementation. Ditto through the rest of the file.

If you put this property up in the root node, then you can omit it
from everywhere else because they'll pick it up as the default
interrupt controller.
