Unless loading these modules from initramfs doesn't work, please use =m. The drivers that are enabled here are going to be enabled for everybody using arm64 defconfig, taking up memory on their platforms, etc. -- With best wishes Dmitry

[PATCH 17/19] arm64: defconfig: enable clock controller, interconnect and pinctrl for QCS8300
