Merge tag 'nomadik-i2c-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into next/dt
From Linus Walleij: Enables the standard Nomadik I2C driver for use on the original Nomadik instead of using a bit-banged driver. * tag 'nomadik-i2c-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik: ARM: nomadik: switch to use the Nomadik I2C driver Signed-off-by: Kevin Hilman <khilman@linaro.org>
