The cutoff date for most board DT patches to get into a release is
around -rc5/-rc6 of the *previous* release: patches should live in
linux-next for a while. Also most pull requests need to "trickle up" the
stream first (from the sunxi tree to the SoC tree, then into mainline).
So -rc1 is out of reach now.

Yes.

Yes, this is the way to go. The maintainers will probably take care of
any minor conflicts (like in the Makefile), so (the upcoming) -rc1
should be the base tree. For new DT files the conflict potential should
be minimal anyway.
Just make sure to run "make dt_binding_check" and "make dtbs_check"
again, because the rules might have been updated meanwhile.

Cheers,
Andre
