/**
 * struct devfreq_cooling_power - Devfreq cooling power ops
 * @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.
