The idea with DT is that you can bake the DT into a board firmware and
then upgrade the kernel without upgrading the DT.

Like I keep saying the problem we've always had is that there's never
been a 1:1 mapping between SoCs and IIS IPs, and of course nobody can
get the documentation on the older SoCs outside of Samsung so...  If it
were a linear march forward in terms of IP it'd be a lot easier :(
