Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade New warnings running 'make CHECK_DTBS=y qcom/qcm6490-idp.dtb' for 20241010110456.829-1-quic_janathot@quicinc.com: arch/arm64/boot/dts/qcom/qcm6490-idp.dtb: bluetooth: 'vddio-supply' is a required property from schema $id: http://devicetree.org/schemas/net/bluetooth/qualcomm-bluetooth.yaml#
