I'm still not convinced about this change.

Re: the commit message about: What about the driver model is not being
fully used without DT?

Overall: What advantage does using DT have to either a developer or an
end-user?

I don't believe this patch fixes and bugs or enables any new features
for an end-user.

From the maintainer perspective: It seems to me that it's far simpler to
have a tiny struct for each device in the C code than to pull in a whole
slew of DT parsing cruft just to work out the same struct at run-time.
As such, this patch can only make it harder to maintain the code since
there's more of it, and it's more complex.

I just don't see the advantage of switching to DT for U-Boot control.
