[PATCH 1/3] dt-bindings: arm: coresight: restrict single port subnodes

Krzysztof Kozlowski
2023-12-06T11:54:25Z

"in-ports" and "out-ports" with single "port" subnode should use
"additionalProperties: false" to disallow any other properties mentioned
by graph schema which are not applicable for this case, e.g.
"address-cells".
