The Exynos PPMU drivers have been located in drivers/devfreq/exynos as devfreq drivers have been the only users of PPMU. There are developers trying to design common PPMU frameworks, including Chanwoo, it is not yet submitted. Because other Exynos5 SoCs have their bus/memif PPMU defined in drivers/devfreq/exynos, adding another ont in another directory seems not appropriate.
