Yes, but in which Linux?  This whole thing started because U-Boot will
no longer accept the DTB used with Linux 4.14.  If each Linux version is
going to have its own incompatible DTB then U-Boot either needs to
decide which one to work with, or work with the vendor DTB (which
would be perferable in my opinion).

An upstreaming review that suggests changing a driver so that it no
longer works with the vendor's DTB is IMHO contraproductive and
against the very idea of DTB, but I suppose there's little that can be
done to affect the review process over at Linux land...  It would be
nice if this weirdness did not spill over on U-Boot/OpenSBI though.
