This can be done once the binding landed. > remoteproc@4080000: 'interconnects' is a required property > arch/arm64/boot/dts/qcom/sc7280-crd.dtb > arch/arm64/boot/dts/qcom/sc7280-herobrine-herobrine-r0.dtb > arch/arm64/boot/dts/qcom/sc7280-herobrine-herobrine-r1.dtb > arch/arm64/boot/dts/qcom/sc7280-idp2.dtb > arch/arm64/boot/dts/qcom/sc7280-idp.dtb This can be fixed by adding an 'interconnects' to either the extension in sc7280-chrome-common.dtsi, or the original node if 'qcom,sc7280-mpss-pas' uses the same interconnect. > remoteproc@4080000: reset-names:1: 'pdc_sync' was expected > arch/arm64/boot/dts/qcom/sc7280-crd.dtb > arch/arm64/boot/dts/qcom/sc7280-herobrine-herobrine-r0.dtb > arch/arm64/boot/dts/qcom/sc7280-herobrine-herobrine-r1.dtb > arch/arm64/boot/dts/qcom/sc7280-idp2.dtb > arch/arm64/boot/dts/qcom/sc7280-idp.dtb > This could be fixed by aligning the reset names of the 'qcom,sc7280-mpss-pas' and 'qcom,sc7280-mss-pil' bindings. The reset is called 'pdc_reset' for 'mpss-pas', and 'pdc_sync' for 'mpss-pil'.
