I think we need some input from the device-tree guys to see whether they would object to us solving this locally (in the PMU node) or not. Personally, I'd much prefer a general way to describe the need for pm-notifiers, but if that's not being looked at then we can cook something specifically for our needs.No input from device-tree guys :(The device tree bindings for power domains is under discussion [1]
Thanks for the information. But it currently for device only, core related stuff are not supported. And is it really good to register power provider for core and let vfp / pmu etc to get it?
