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"
