Question is whether anyone outside of ACPI will ever need the generic
interface. Making it generic based on guesswork could be a wasted effort
that Rafael and others will have to maintain. The mode file could go
under /sys/firmware/acpi if interface is made ACPI-specific.

Will be good if you could demonstrate a need in making interface
generic, if there are any devices on your mind that could make use of it
right away. Old interface can be deprecated if a better new appears.

Either way is okay to me, but Rafael is the PM expert and I'd do as he
wants it to be.
