The DT has always supposed to have been the same one as the Linux
Kernel, to make things easier for developers as they would only need one
DT, not two. For systems that use the EFI loader we pass the same DT to
the OS which can simplify life.

If the DT is not upstream it really should be being submitted upstream
and not just never upstreamed. I know this is more challenging in some
cases than others.

That is usually easiest, yes.
