No, top-level should have broadest constraints. In your case it is min/maxItems. Description is completely redundant.

Previously CDNS variant had two items means it had "j721e-intg". Now it's something else. First, this is an ABI break. Second, there is no explanation at all for it in the commit msg! Looks like random change. Read carefully writing-bindings doc. Best regards, Krzysztof
