[PATCH] i2c: s3c2410: dont need CPU_FREQ transitions for exynos series

2013-10-11 Thread Naveen Krishna Chatradhi
The exynos5 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 cpu_freq_transition only for non Exynos SoCs. Th
