You did not add any new information. This is always a list, always phandles and always reserved memory regions. So what does it bring? Please do not upstream random junk from your downstream kernel. :( Best regards, Krzysztof

Maybe I was not that clear, so to explain more - entries must be constrained, so provide widest constraints in top-level properties place and narrow the constrains per variant in allOf:if:then: like: https://elixir.bootlin.com/linux/v6.8/source/Documentation/devicetree/bindings/ufs/qcom,ufs.yaml#L132 Best regards, Krzysztof
