Cc'ing Javi (which you should have as he wrote the power-thing for cpu-cooling).

Bindings are (normally) supposed to be general than a platform specific.

Then just don't add things in the first place.

The bindings don't fix the values for static power, but just provides a field for platforms to use. Everyone can then send its own power figures. Why do you thing it can't be generalized?

Maybe, we should still capture it.
@Javi ?
