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

Linus,
here is the pull request from the i2c subsystem for 3.13:
* new drivers for exynos5, bcm kona, and st micro
* bigger overhauls for drivers mxs and rcar
* typical driver bugfixes, cleanups, improvements
* got rid of the superfluous 'driver' member in i2c_client struct
This touches a few d
