Generally we do try to upstream as much as possible, but in the case of
the devicetree we're not sure what the benefits would be for the community
and for us, so we don't have an opinion on this yet.
We use a few of the Foundation's overlays with parameters tailored to the
Revolution Pi, plus a custom overlay. All of that is public:

Thanks for your interest,
