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:
 "A number of new drivers get added this time, along with many
  low-priority bugfixes. The most interesting changes by subsystem are:

  bus drivers:
   - Updates to the Broadcom bus interface driver to support newer SoC
     types
   - The TI OMAP sysc driver now supports updated DT bindings

  memory controllers:
   - A new driver for Tegra186 gets added
   - A new driver for the ti-emif sram, to allow relocating
     suspend/resume handlers there

  SoC specific:
   - A new driver for Qualcomm QMI, the interface to the modem on MSM
     SoCs
   - A new driver for power domains on the actions S700 SoC
   - A driver for the Xilinx Zynq VCU logicoreIP

  reset controllers:
   - A new driver for Amlogic Meson-AGX
   - various bug fixes

  tee subsystem:
   - A new user interface got added to enable asynchronous communication
     with the TEE supplicant.
   - A new method of using user space memory for communication with the
     TEE is added"
