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

Pull ARM SoC driver updates from Olof Johansson:
 "Driver updates for ARM SoCs.  Some for SoC-family code under
  drivers/soc, but also some other driver updates that don't belong
  anywhere else.  We also bring in the drivers/reset code through
  arm-soc.

  Some of the larger updates:

   - Qualcomm support for SMEM, SMSM, SMP2P.  All used to communicate
     with other parts of the chip/board on these platforms, all
     proprietary protocols that don't fit into other subsystems and live
     in drivers/soc for now.

   - System bus driver for UniPhier

   - Driver for the TI Wakeup M3 IPC device

   - Power management for Raspberry PI

  + Again a bunch of other smaller updates and patches"
