The biggest thing is that it should describe the *hardware*, in a
fashion which is completely OS-agnostic.

The same device-tree binding should work for Solaris, *BSD, Windows,
eCos, and everything else.

I've heard tales of people having to keep device-tree files for their
board tightly in sync with the specific *version* of the Linux kernel
that they were shipped with.

That makes me very sad, because it almost certainly means that someone
has done it completely and utterly wrong.
