The Marvell Armada 3700 is a family of ARMv8 CA53 SoCs. This commit
introduces the Device Tree binding that documents the top-level
compatible strings for Armada 3700 based platforms.

+Marvell Armada 37xx Platforms Device Tree Bindings
+--------------------------------------------------
+
+Boards using a SoC of the Marvell Armada 37xx family must carry the
+following root node property:
+
+ - compatible: must contain "marvell,armada3710"

Are we sure at this point that the 3720 is a strict super-set of the
3710 ?

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.

Thanks,

Gregory
