Merge tag 'arm-drivers-v5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

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:

  SCMI firmware:
   - add support for a completion interrupt

  Reset controllers:
   - new driver for BCM4908
   - new devm_reset_control_get_optional_exclusive_released() function

  Memory controllers:
   - Renesas RZ/G2 support
   - Tegra124 interconnect support
   - Allow more drivers to be loadable modules

  TEE/optee firmware:
   - minor code cleanup

  The other half of this is SoC specific drivers that do not belong into
  any other subsystem, most of them living in drivers/soc:

   - Allwinner/sunxi power management work
   - Allwinner H616 support

   - ASpeed AST2600 system identification support

   - AT91 SAMA7G5 SoC ID driver
   - AT91 SoC driver cleanups

   - Broadcom BCM4908 power management bus support

   - Marvell mbus cleanups

   - Mediatek MT8167 power domain support

   - Qualcomm socinfo driver support for PMIC
   - Qualcomm SoC identification for many more products

   - TI Keystone driver cleanups for PRUSS and elsewhere"
