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

Pull ARM SoC driver updates from Arnd Bergmann:
 "As usual, the drivers/tee and drivers/reset subsystems get merged
  here, with the expected set of smaller updates and some new hardware
  support. The tee subsystem now supports device drivers to be attached
  to a tee, the first example here is a random number driver with its
  implementation in the secure world.

  Three new power domain drivers get added for specific chip families:
   - Broadcom BCM283x chips (used in Raspberry Pi)
   - Qualcomm Snapdragon phone chips
   - Xilinx ZynqMP FPGA SoCs

  One new driver is added to talk to the BPMP firmware on NVIDIA
  Tegra210

  Existing drivers are extended for new SoC variants from NXP, NVIDIA,
  Amlogic and Qualcomm"
