That's chill, however I can't reproduce this, make dt_bindings_check in the
mainline kernel does not yield this warning (after pip install
--upgrade --user dtschema
and yamllint is installed and all), so right now my only way of testing this
patch is to mail it to the mailing list and have it tested by Rob's bot.

I just don't understand what I'm supposed to do... drop the dash-space "- " in
front of "- ports"? Then the bot will be happy?

(This patch was added in response to Rob's comments
"this should probably be in dsa.yaml".)

We can also just drop the patch if this whole thing upsets the tooling, it's
just intended as a generalization of this requirement as can be seen in
Documentation/devicetree/bindings/net/dsa/qca8k.yaml
which in turn can do that because it is not using the generic def.
