In this case there are no differences between the DT in the kernel repo
and what we put in U-Boot. The main reason for me holding back the switch
to OF_UPSTREAM for the H616 was indeed the rather slow update cadence,
which somewhat slows down upstreaming of new boards like this. Doing this
separately gives us a bit more control and freedom to take DT patches
early, for instance when they appear in some Linux -rc1, or even before
that (linux-next).
I explained my position in more detail here:
https://lore.kernel.org/u-boot/191A0F66-E2AE-4D1B-ACBE-E411E135BB61@arm.com/
I think Tom partly convinced me that regular updates together with
cherry-picking should solve most of those problems, so I will probably do
the switch for the next cycle.
Cheers,
Andre
