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
