I'd like that in sysfs, but I am unsure if > we are allowed to due to the other information reported there. For power and voltage, I believe there are standard hwmon interfaces. It would probably be best to expose it via those. For clocks/pcie, I think you can already determine them via the existing pp sysfs interfaces.
