Does this really ever differ for the SoCs, and even if it does why do we need
to encode it in DT.  Can?t we determine it via the compatible setting?

The two offsets could be hard coded, especially based on the compatible.

But I don't know if it's worth respinning this just to get those two number out
of here. Also this is now "symmetric" with the smd use cases, where it
shouldn't be hard coded.

I do think its worth respinning until the DT is agreed to as we shouldn?t be changing the binding.

I?m not sure how being ?symmetric? with the smd use case maters if we are treating this RPM support vs RPM-SMD as two different things.
