I've pushed out an updated series against v6.6 earlier today in case anyone wants something specifically against v6.6, but I don't think there is any pressing reason to re-test. The only ACPI change between the two is: 9b311b7313d6 ACPI: NFIT: Install Notify() handler before getting NFIT table and the only arm64 changes are in dts files. Nothing significant in kernel/ and nothing in drivers/base/. So I think at this point, I will pause waiting for 6.7-rc1 (which I'll do an updated patch set, since it will include changes queued up) and hopefully followed by Rafael's comments. Maybe James will also have some time to work on this again. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up. Decent connectivity at last!
