Merge tag 'drivers-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "There are cleanups and minor bugfixes across several SoC specific
  drivers, for Qualcomm, Samsung, NXP i.MX, AT91, Tegra, Keystone,
  Renesas, ZynqMP

  Noteworthy new features are:

   - The op-tee firmware driver gains support for asynchronous
     notifications from secure-world firmware.

   - Qualcomm platforms gain support for new SoC types in various
     drivers: power domain, cache controller, RPM sleep, soc-info

   - Samsung SoC drivers gain support for new SoCs in ChipID and PMU, as
     well as a new USIv2 driver that handles various types of serial
     communiction (uart, i2c, spi)

   - Renesas adds support for R-Car S4-8 (R8A779F0) in multiple drivers,
     as well as memory controller support for RZ/G2L (R9A07G044).

   - Apple M1 gains support for the PMGR power management driver"
