Merge tag 'mxs-fixes-3.9-4' of git://git.linaro.org/people/shawnguo/linux-2.6 into fixes
From Shawn Guo <shawn.guo@linaro.org>:
The mxs fixes for 3.9, take 4:
- A couple mxs boards that run I2C at 400 kHz experience some unstable
issue occasionally. Slow down the clock speed to have I2C work
reliably.
