For this specific board with 2x 10G SFP+, i doubt it will be a pure ACPI system. It could be a mixed system, ACPI for the simple bits, and DT for the advanced parts. Could this MFD appear on boards which could be pure ACPI? Maybe, if their networking is simple enough, or Linux is not in control of the low level details. There are some Intel Puzzle devices which could potentially use the MFD. Andrew
