Merge tag 'imx-soc-3.12' into imx/dt
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
