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

Pull ARM SoC-related driver updates from Olof Johansson:
 "Various driver updates for platforms and a couple of the small driver
  subsystems we merge through our tree:

   - A driver for SCU (system control) on NXP i.MX8QXP

   - Qualcomm Always-on Subsystem messaging driver (AOSS QMP)

   - Qualcomm PM support for MSM8998

   - Support for a newer version of DRAM PHY driver for Broadcom (DPFE)

   - Reset controller support for Bitmain BM1880

   - TI SCI (System Control Interface) support for CPU control on AM654
     processors

   - More TI sysc refactoring and rework"
