commit add3eeed3683e2636ef524db48e1a678757c8e96 upstream.
We report "frequencies" (actual-frequency, requested-frequency) as the number of accumulated cycles so that the average frequency over that period may be determined by the user. This means the units we report to the user are Mcycles (or just M), not MHz.
