Merge tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "A couple of subsystems have their own subsystem maintainers but choose
  to have the code merged through the soc tree as upstream, as the code
  tends to be used across multiple SoCs or has SoC specific drivers
  itself:

   - memory controllers:

     Krzysztof Kozlowski takes ownership of the drivers/memory subsystem
     and its drivers, starting out with a set of cleanup patches.

     A larger driver for the Tegra memory controller that was
     accidentally missed for v5.8 is now added.

   - reset controllers:

     Only minor updates to drivers/reset this time

   - firmware:

     The "turris mox" firmware driver gains support for signed firmware
     blobs The tegra firmware driver gets extended to export some debug
     information Various updates to i.MX firmware drivers, mostly
     cosmetic

   - ARM SCMI/SCPI:

     A new mechanism for platform notifications is added, among a number
     of minor changes.

   - optee:

     Probing of the TEE bus is rewritten to better support detection of
     devices that depend on the tee-supplicant user space. A new
     firmware based trusted platform module (fTPM) driver is added based
     on OP-TEE

   - SoC attributes:

     A new driver is added to provide a generic soc_device for
     identifying a machine through the SMCCC ARCH_SOC_ID firmware
     interface rather than by probing SoC family specific registers.

     The series also contains some cleanups to the common soc_device
     code.

  There are also a number of updates to SoC specific drivers, the main
  ones are:

   - Mediatek cmdq driver gains a few in-kernel interfaces

   - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
     support for additional SoC variants

   - The Qualcomm GENI core code gains interconnect path voting and
     performance level support, and integrating this into a number of
     device drivers.

   - A new driver for Samsung Exynos5800 voltage coupler for

   - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
     specific device drivers

   - Updates to the TI K3 Ring Accelerator driver"
