From 10d929a26aa3846901d4c15bee8ee823d930a4f2 Mon Sep 17 00:00:00 2001 From: Jonghwa Lee Date: Thu, 15 May 2014 18:42:34 +0900 Subject: PM / devfreq : Make exynos4 busfreq driver to use PPMU not DMC internal one. This patch modifies exynos4 busfreq driver to use global PPMU not DMC block's internal PMU. The PPMU has different event set with DMC's and it'll be more adaquate to profile bus utilization.
