That's right. At least in the i.MX world we never made a strong
guarantee in that way.

Still we should not break it deliberately if there isn't a good reason
to do so. And I _feel_ that "DT schema isn't able to express the SoC
integration" isn't a good enough reason to break things.

But maybe there is a way to describe this in the DT schema, that we
aren't aware of yet. I'm not quite up-to-date with all the DT schema
stuff...

Lucas
