+ * @get_real_power: When this is set, the framework uses it to ask the
+ * device driver for the actual power.
+ * Some devices have more sophisticated methods
+ * (like power counters) to approximate the actual power
+ * that they use.
+ * This function provides more accurate data to the
+ * thermal governor. When the driver does not provide
+ * such function, framework just uses pre-calculated
+ * table and scale the power by 'utilization'
+ * (based on 'busy_time' and 'total_time' taken from
+ * devfreq 'last_status').
+ * The value returned by this function must be lower
+ * or equal than the maximum power value
+ * for the current state
+ * (which can be found in power_table[state]).
+ * When this interface is used, the power_table holds
+ * max total (static + dynamic) power value for each OPP.
