Currently the dtpm supports the CPUs via cpufreq and the energy model. This change provides the same for the device which supports devfreq. Each device supporting devfreq and having an energy model can be added to the hierarchy. The concept is the same as the cpufreq DTPM support: the QoS is used to aggregate the requests and the energy model gives the value of the instantaneous power consumption ponderated by the load of the device.
