Pull ARM SoC driver updates from Arnd Bergmann:
 "Updates for SoC specific drivers include a few subsystems that have
  their own maintainers but send them through the soc tree:

  TEE/OP-TEE:
   - Add tracepoints around calls to secure world

  Memory controller drivers:
   - Minor fixes for Renesas, Exynos, Mediatek and Tegra platforms
   - Add debug statistics to Tegra20 memory controller
   - Update Tegra bindings and convert to dtschema

  ARM SCMI Firmware:
   - Support for modular SCMI protocols and vendor specific extensions
   - New SCMI IIO driver
   - Per-cpu DVFS

  The other driver changes are all from the platform maintainers
  directly and reflect the drivers that don't fit into any other
  subsystem as well as treewide changes for a particular platform.

  SoCFPGA:
   - Various cleanups contributed by Krzysztof Kozlowski

  Mediatek:
   - add MT8183 support to mutex driver
   - MMSYS: use per SoC array to describe the possible routing
   - add MMSYS support for MT8183 and MT8167
   - add support for PMIC wrapper with integrated arbiter
   - add support for MT8192/MT6873

  Tegra:
   - Bug fixes to PMC and clock drivers

  NXP/i.MX:
   - Update SCU power domain driver to keep console domain power on.
   - Add missing ADC1 power domain to SCU power domain driver.
   - Update comments for single global power domain in SCU power domain
     driver.
   - Add i.MX51/i.MX53 unique id support to i.MX SoC driver.

  NXP/FSL SoC driver updates for v5.13
   - Add ACPI support for RCPM driver
   - Use generic io{read,write} for QE drivers after performance
     optimized for PowerPC
   - Fix QBMAN probe to cleanup HW states correctly for kexec
   - Various cleanup and style fix for QBMAN/QE/GUTS drivers

  OMAP:
   - Preparation to use devicetree for genpd
   - ti-sysc needs iorange check improved when the interconnect target
     module has no control registers listed
   - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to
     avoid issues with missing resources and unnecessary deferred probe
   - ti-sysc debug option can now detect more devices
   - ti-sysc now warns if an old incomplete devicetree data is found as
     we now rely on it being complete for am3 and 4
   - soc init code needs to check for prcm and prm nodes for omap4/5 and
     dra7
   - omap-prm driver needs to enable autoidle retention support for
     omap4
   - omap5 clocks are missing gpmc and ocmc clock registers
   - pci-dra7xx now needs to use builtin_platform_driver instead of
     using builtin_platform_driver_probe for deferred probe to work

  Raspberry Pi:
   - Fix-up all RPi firmware drivers so as for unbind to happen in an
     orderly fashion
   - Support for RPi's PoE hat PWM bus

  Qualcomm
   - Improved detection for SCM calling conventions
   - Support for OEM specific wifi firmware path
   - Added drivers for SC7280/SM8350: RPMH, LLCC< AOSS QMP"
