Precisely. If nothing else as a general guideline this keeps us honest,
and prevents us from embedding arbitrary implementation details into
bidnings that cause pain later when we want to change things at either
end.
There are already otehr users of these bindings, so we can't really
claim they're strictly Linux-specific anyhow.

As far as I am aware, it's the point of view shared by the device tree
maintainers, and it's been that way for a while.
I don't really follow your concern. For one thing were this followed
more strictly this file wouldn't need patching at all to correct for
this Linux-internal rework...
Thanks,
Mark.
