    Description
    -----------

    +1) Processor TDP (Thermal design power)
    +
    +Given a fixed frequency and voltage, the power consumption of a
    +processor varies based on the workload being executed. Derated power
    +is the power consumed when running a specific application. Thermal
    +design power (TDP) is an example of derated power.
    +
    This driver permits reading of registers providing power information
    -of AMD Family 15h and 16h processors.
    +of AMD Family 15h and 16h processors via TDP algorithm.

    For AMD Family 15h and 16h processors the following power values can
    be calculated using different processor northbridge function
