Just a little note before I forget..

I picked this up yesterday (in prep for adding sa8540p support here),
and noticed the same thing as Bhupesh when validating dtbs with
the requested changes (not duplicating snsp,dwmac.yaml). I ended up
tracking it down to a (fixed) bug in dtschema:

    https://github.com/devicetree-org/dt-schema/commit/e503ec1115345bdfa06b96c9d6c4496457cbd75b

And a little test output showing before and after (fix is in the 2022.12
release):

I'll go ahead and make the adjustments and pull this series into mine
adding sa8540p support, thanks for starting it!
