[PATCH 2/2] dt-bindings: usb: realtek,rts5411: Disallow unevaluated properties

From: Krzysztof Kozlowski

Date: Mon Jan 12 2026 - 04:02:01 EST


Review given to v2 [1] of commit 76cbb3eabf0b ("dt-bindings: usb:
realtek,rts5411: Adapt usb-hub.yaml") asked to use
unevaluatedProperties, but this was ignored by the author probably
because current dtschema does not allow to use both additionalProperties
and unevaluatedProperties. As an effect, this binding does not end with
unevaluatedProperties and allows any properties to be added.

Fix this by reverting the approach suggested at v2 review and using
simpler definition of "reg" constraints.
