* PM / devfreq: Add Exynos5-bus devfreq driver for Exynos5250Abhilash Kesavan2013-06-03
Exynos5-bus device devfreq driver monitors PPMU counters and adjusts operating frequencies and voltages with OPP. ASV should be used to provide appropriate voltages as per the speed group of the SoC rather than using a constant 1.025V.
