Merge tag 'imx-soc-3.14' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc

From Shawn Guo:
i.MX SoC changes for 3.14:
 - Add the initial i.MX50 SoC support
 - Support device tree boot for i.MX35
 - Move imx5 clock driver to use macros for clock ID
 - Some random updates and non-critical fixes on clock drivers
 - A few defconfig updates and minor cleanups
