Well, they depend on ACPI too and it doesn't look like there is anything
more fine grained that could be used here.
Also I'm not sure if adding ACPI_DPTF (bool, disabled by default and
depending on x86) would help a lot.

Obviously an oversight on my part, sorry.
I think that changing it to "dptf_power" (and analogously for the FIVR
participant driver) should work. Srinivas?

So you're saying this is going to be present in current and future
hardware so might as well enable it?

Makes sense.

Yes. [Only on clients AFAICS, but still.]
In the meantime I have concluded that having a submenu for it would
make sense, though. At least from the clarity POV.
