Well, as the person who came up with the flattened device-tree format in
the first place I suppose I qualify as a "device-tree" guy here :-)

At the moment, I'd say Grant (and to some extent Jeremy Kerr) are the
guys in charge though, but yes, I agree with you, there's a tendency to
be too over-exited and to want to do "too much" with the DT and that is
counter productive. It's a good tool but it's not going to solve world
hunger and in some places an ad-hoc bit of C code is a better option :)

Now, I don't think Grant is totally off the tracks here but I must admit
I haven't taken the time to ensure I understand perfectly everybody's
position in that debate. At least I made mine clear, hope this helps :-)

Cheers,
Ben.
