Merge tag 'imx-weim-3.12' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc
From Shawn Guo:
This is a patch series that updates imx-weim bus driver to have it
support more i.MX SoCs. Because there is no maintainer for
drivers/bus so far, I'm forwarding it through IMX tree for 3.12 merge
window.
