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:
 "The most noteworthy SoC driver changes this time include:

   - The TEE subsystem gains an in-kernel interface to access the TEE
     from device drivers.

   - The reset controller subsystem gains a driver for the Qualcomm
     Snapdragon 845 Power Domain Controller.

   - The Xilinx Zynq platform now has a firmware interface for its
     platform management unit. This contains a firmware "ioctl"
     interface that was a little controversial at first, but the version
     we merged solved that by not exposing arbitrary firmware calls to
     user space.

   - The Amlogic Meson platform gains a "canvas" driver that is used for
     video processing and shared between different high-level drivers.

  The rest is more of the usual, mostly related to SoC specific power
  management support and core drivers in drivers/soc:

   - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
     features related to power and reset control.

   - The Mediatek mt8183 and mt6765 SoC platforms gain support for their
     respective power management chips.

   - A new driver for NXP i.MX8, which need a firmware interface for
     power management.

   - The SCPI firmware interface now contains support estimating power
     usage of performance states

   - The NVIDIA Tegra "pmc" driver gains a few new features, in
     particular a pinctrl interface for configuring the pads.

   - Lots of small changes for Qualcomm, in particular the "smem" device
     driver.

   - Some cleanups for the TI OMAP series related to their sysc
     controller.

  Additional cleanups and bugfixes in SoC specific drivers include the
  Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"
