Duly noted. :)

You need to also document the compatibles in bindings file for boards.
It would be nice to convert
Documentation/devicetree/bindings/arm/marvell/marvell,orion5x.txt to DT
Schema (see armada-7k-8k.yaml for example), but it is not a requirement.

Ah, I hadn't even noticed them before. Will look into this.
