Merge tag 'imx-soc-3.12' of git://git.linaro.org/people/shawnguo/linux-2.6 into next/soc
From Shawn Guo:
It contains a bunch of imx soc updates for 3.12.
- Add more ethernet phy fixups for imx6 boards
- Add some missing imx6q clocks into clock driver
- Add new clock types fixup mux and div to work around some ugly
hardware defect
- Consolidate L2 cache initialization function, so that it can be used
on more i.MX SoCs
- Replace magic numbers in mach-imx6q.c with well defined macros
- Small fixes for imx6q and pllv3 clock drivers
- Some random updates on imx defconfig files
