I sent this patch to start the discussion, some things I found: 1) Some interconnects are missing from arm defconfig. Should they be =y too ? $ grep CONFIG_INTERCONNECT_QCOM arch/arm/configs/qcom_defconfig CONFIG_INTERCONNECT_QCOM=y CONFIG_INTERCONNECT_QCOM_MSM8974=m CONFIG_INTERCONNECT_QCOM_SDX55=m 2) Some interconnects are missing from arm64 defconfig (which should probably be in there) (I have included just two examples): $ grep CONFIG_INTERCONNECT drivers/interconnect/qcom/Makefile obj-$(CONFIG_INTERCONNECT_QCOM_QCS615) += qnoc-qcs615.o obj-$(CONFIG_INTERCONNECT_QCOM_SM7150) += qnoc-sm7150.o I can handle these in follow-up or v2 of the patchset as follow-up commits, please let me know what you'd prefer.
