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

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