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

Pull ARM SoC driver specific changes from Olof Johansson:
 "A collection of mostly SoC-specific driver updates:
   - a handful of pincontrol and setup changes
   - new drivers for hwmon and reset controller for vexpress
   - timing support updates for OMAP (gpmc and other interfaces)
   - plus a collection of smaller cleanups"
