Bah, sending a patch is good too, don't be too hard there. I for one
prefer the approach of sending a patch first.

We probably need to improve the documentation in fact. Maybe with a step
by step HOWTO create your device-tree with examples for typical things
like PCI etc.. and the rational of why for each of these, we chose to do
XXX instead of YYY...

They aren't -that- good when you come out of the blue and don't know
where to start. I think a tutorial based on building a tree for an
example board step by step would be best.
