Which patch are you referring to? If you mean the ACPI v5.0 vs v5.1 patch authored by Ard, then yes I know, I instigated it's existence due to these devices. DT will *always* be more enabled than ACPI, so it's advised that you use DT for anything useful. ACPI booting is ideal for things like installing distros however, since they do not tend to provide DTBs in their installers.
