I think we are in the same situation with the Armada 380 with the other
Armada 38x. At this point the 3720 is a super-set of the 3710.

Actually, we only said that the 3720 is compatible with the 3710 not
really a strict super-set. More over, for a 3720 we must use
marvell,armada3720 _and_ marvell,armada3710, and in case of conflict
marvell,armada3720 must be used.
I really prefer using marvell,armada3710 as common compatible for all
the Armada 3700 SoCs, that having no common compatible at all.
Thanks,
Gregory
