Nick, i can do a patch, but I really would like to understand why this change makes it work. In the end it would be less patching.   Our sun50i-h618-transpeed-8k618-t.dtb does not have "osc32k" nor "osc32k-out" so i don't think it is dtb related.   To try it, it is two additional changes: - change kernel config to CONFIG_SUN6I_RTC_CCU=y - remove the tree patches:         patches.armbian/drv-rtc-sun6i-support-RTCs-without-external-LOSCs.patch         patche
