Merge tag 'drivers-5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "These are all the driver updates for SoC specific drivers. There are a
  couple of subsystems with individual maintainers picking up their
  patches here:

   - The reset controller subsystem add support for a few new SoC
     variants to existing drivers, along with other minor improvements

   - The OP-TEE subsystem gets a driver for the ARM FF-A transport

   - The memory controller subsystem has improvements for Tegra,
     Mediatek, Renesas, Freescale and Broadcom specific drivers.

   - The tegra cpuidle driver changes get merged through this tree this
     time. There are only minor changes, but they depend on other tegra
     driver updates here.

   - The ep93xx platform finally moves to using the drivers/clk/
     subsystem, moving the code out of arch/arm in the process. This
     depends on a small sound driver change that is included here as
     well.

   - There are some minor updates for Qualcomm and Tegra specific
     firmware drivers.

  The other driver updates are mainly for drivers/soc, which contains a
  mixture of vendor specific drivers that don't really fit elsewhere:

   - Mediatek drivers gain more support for MT8192, with new support for
     hw-mutex and mmsys routing, plus support for reset lines in the
     mmsys driver.

   - Qualcomm gains a new "sleep stats" driver, and support for the
     "Generic Packet Router" in the APR driver.

   - There is a new user interface for routing the UARTS on ASpeed BMCs,
     something that apparently nobody else has needed so far.

   - More drivers can now be built as loadable modules, in particular
     for Broadcom and Samsung platforms.

   - Lots of improvements to the TI sysc driver for better
     suspend/resume support"

  Finally, there are lots of minor cleanups and new device IDs for
  amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
  layerscape, allwinner, broadcom, and omap"
