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:

  Among the larger pieces:

   - Power management improvements for TI am335x and am437x (RTC
     suspend/wake)

   - Misc new additions for Amlogic (socinfo updates)

   - ZynqMP FPGA manager

   - Nvidia improvements for reset/powergate handling

   - PMIC wrapper for Mediatek MT8516

   - Misc fixes/improvements for ARM SCMI, TEE, NXP i.MX SCU drivers"
