Merge tag 'imx-soc-3.11' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc

From Shawn Guo:

imx soc changes for 3.11:

* New SoCs i.MX6 Sololite and Vybrid VF610 support
* imx5 and imx6 clock fixes and additions
* Update clock driver to use of_clk_init() function
* Refactor restart routine mxc_restart() to get it work for DT boot
  as well
* Clean up mxc specific ulpi access ops
* imx defconfig updates
