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. * tag 'mxs-fixes-3.9-4' of git://git.linaro.org/people/shawnguo/linux-2.6: ARM: mxs: Slow down the I2C clock speed Signed-off-by: Arnd Bergmann <arnd@arndb.de>
