Distinguish between Armada 3700 family, Armada 3710 SoC and Armada 3720 SoC.
Armada 3720 DB is name of the board with Armada 3720 SoC, so correctly
indicate SoC in example.

The change is an ABI break, which looks reasonable, but still platform
maintainer should comment on it. Especially on the aspect why the
marvell,armada3710 fallback was chosen at the first place.
Unfortunately none of Marvel folks were CCed here, so you will need to
resend it. Otherwise no one will apply it, regardless of our ack.

I do not think this is ABI break but rather incorrect documentation and
bug in some board dts files.

I was not involved in the armada37xx enablement. I have no idea why
marvell,armada3710 fallback was chosen.
Gregory might know, he is the author of this file.
It does however seem reasonable. And a grep does suggest this
compatible is purely cosmetic, it is not matched on anywhere.

This documentation is the ABI, especially if actually implemented in the
DTS files, therefore by all definitions of DT ABI this is an ABI break.
What you are saying about "incorrect documentation and bug in some DTS
files" is a good reason to break the ABI, but it is still a break.

I think it is now clear what we both mean, just we used different
terminology for the same thing.

This looks like platform bindings, so the platform maintainers. Would be
easier for them to pick it up, if they were CCed. :)
I actually hoped they will pick up also fix for maintainers entry:
