Hi Vincent,

So, IMO, defining the power topology is a good starting point and I think it's better to separate the patches from the energy saving algorithms like packing. We need to agree on what information we have
Daniel and Tuukka who are working in cpuidle consolidation in the scheduler, are also interested in using similar topology information than me. I have made 1 patchset only because the information was only used here. So I can probably make a separate patchset of the power topology description in DT.

(C-state details, coupling, power gating) and what we can/need to expose to the scheduler. This can be revisited once we start implementing/refining the energy awareness.
