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

Pull ARM SoC driver updates from Arnd Bergmann:
 "New SoC specific drivers:

   - NVIDIA Tegra PM Domain support for newer SoCs (Tegra186 and later)
     based on the "BPMP" firmware

   - Clocksource and system controller drivers for the newly added
     Action Semi platforms (both arm and arm64).

  Reset subsystem, merged through arm-soc by tradition:

   - New drivers for Altera Stratix10, TI Keystone and Cortina Gemini
     SoCs

   - Various subsystem-wide cleanups

  Updates for existing SoC-specific drivers

   - TI GPMC (General Purpose Memory Controller)

   - Mediatek "scpsys" system controller support for MT6797

   - Broadcom "brcmstb_gisb" bus arbitrer

   - ARM SCPI firmware

   - Renesas "SYSC" system controller

  One more driver update was submitted for the Freescale/NXP DPAA data
  path acceleration that has previously been used on PowerPC chips. I
  ended up postponing the merge until some API questions for its unusual
  MMIO access are resolved"
