2013-11-18 Thread Naveen Krishna Chatradhi
For Exynos4 and Exynos5 SoCs from Samsung the i2c clock is based on a fixed 66 MHz peripheral clock, and therefore is completely independent of the cpu frequency. Thus, registering for a CPU freq notifier is very wasteful. This patch modifes the code such that, i2c bus registers to
