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. > > If that's not the case, then it would be somewhat weird for a platform > using the 3720 platform to carry the marvell,armada3710 compatible > string, no? 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.
