Thanks for the conversion. I think this is still not what we want. The
main problem is of course in the original binding, not your conversion.
Compatible armada380 above alone is not correct. This is SoC and SoC
compatible cannot be used alone, because it is not specific enough to
differentiate boards. Same applies for further lists, which I removed
from the quote, for the same reasons.

What we could do here is to fix this instead of pure conversion:
1. Add this binding file with new compatibles for existing boards and
drop the TXT file, with explanation that you actually document properly
all existing board compatibles.
2. Add compatibles to existing DTS.
3. Add your new board compatibles.

At least this is what I would do for typical cases, but as I said
before, Marvell here is in some surprising limbo state.
Best regards,
Krzysztof
