Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC driver specific changes from Arnd Bergmann:

 - Updates to the ux500 cpufreq code

 - Moving the u300 DMA controller driver to drivers/dma

 - Moving versatile express drivers out of arch/arm for sharing with arch/arm64

 - Device tree bindings for the OMAP General Purpose Memory Controller
