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

Pull ARM SoC driver updates from Kevin Hilman:
 "Some of these are for drivers/soc, where we're now putting
  SoC-specific drivers these days.  Some are for other driver subsystems
  where we have received acks from the appropriate maintainers.

  Some highlights:

   - simple-mfd: document DT bindings and misc updates
   - migrate mach-berlin to simple-mfd for clock, pinctrl and reset
   - memory: support for Tegra132 SoC
   - memory: introduce tegra EMC driver for scaling memory frequency
   - misc. updates for ARM CCI and CCN busses"
