I can't say for sure, but adding "type: object" here and removing it
from mediatek,mt7530.yaml still causes the same issue I mention below.
Rob's initial suggestion for this patch set (which was basically the
entire implementation... many thanks again Rob) can be found here:
https://lore.kernel.org/netdev/20221104200212.GA2315642-robh@kernel.org/
>From what I can tell, the omission of "type: object" here was
intentional. At the very least, it doesn't seem to have any effect on
warnings.

Without the 'object' type here, I get the following warning:
Documentation/devicetree/bindings/net/dsa/mediatek,mt7530.yaml: patternProperties:^(ethernet-)?ports$:patternProperties:^(ethernet-)?port@[0-9]+$: 'anyOf' conditional failed, one must be fixed:
'type' is a required property
'$ref' is a required property

I'm testing this now and I'm noticing something is going on with the
"ref: dsa-port.yaml"
Everything seems to work fine (in that I don't see any warnings) when I
have this diff:
