I don't think these is any such decision, I'm just asking. I know
that we only want to see DT on new archs and old hairy board code
should be ridded using DT ... So I just want to know what the
situation is like wrt Super-H.

Um so as an upstream maintainer I don't really know what to do
at this point :-)

But a DT-only driver is uncontroversial so I'd merge that.

Okay that sounds good...
