Yes, having a interface which can also control clocks is great. I used to write some code myself to debug clocks, so I have the same feeling with what you said.
BTW, 'cheers' is normally used in Australia and New Zealand. Are you from there? Just curious. :)

That being said, I'm not against $SUBJECT patch, but I question it's usefulness in terms of PM. What's more valuable for PM is the statitics and knobs exported on a per-device level by the runtime PM core (and AFAICT, already included into tools like powertop.)
IIRC, Vincent's suggestion is more valid for the HW guys who want to test out all kinds of possibilities *before* the OS and the support for the drivers becomes mature enough to concentrate on statistics and so on. Even I remember our HW guys requesting for bersek controls over regulators and clocks as a part of platform validation, when the OS was not mature enough in terms of a complete system-support.
Cheers!
