Pull ARM SoC driver updates from Arnd Bergmann:
 "Driver updates for ARM SoCs, including a couple of newly added
  drivers:

   - A new driver for the power management controller on TI Keystone

   - Support for the prerelease "SCPI" firmware protocol that ended up
     being shipped by Amlogic in their GXBB SoC.

   - A soc_device can now be matched using a glob from inside the
     kernel, when another driver wants to know the specific chip it is
     running on and cannot find out from DT, firmware or hardware.

   - Renesas SoCs now support identification through the soc_device
     interface, both in user space and kernel.

   - Renesas r8a7743 and r8a7745 gain support for their system
     controller

   - A new checking module for the ARM "PSCI" (not to be confused with
     "SCPI" mentioned above) firmware interface.

   - A new driver for the Tegra GMI memory interface

   - Support for the Tegra firmware interfaces with their power
     management controllers

  As usual, the updates for the reset controller framework are merged
  here, as they tend to touch multiple SoCs as well, including a new
  driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp
  interface.

  The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
  Rockchips SoCs see some further updates"
