Merge tag 'soc-drivers-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "There are a few added drivers, but mostly the normal maintenance to
  drivers for firmware, memory controller and other soc specific
  hardware:

   - The NXP QuickEngine gets modern MSI support, which allows some
     cleanups to the GICv3 irqchip chip driver

   - A new SoC specific driver for the Renesas R-Car MFIS unit is added,
     encapsulating support for the on-chip mailbox and hwspinlock
     implementations that are not easily separated into individual
     drivers

   - The Qualcomm SoC drivers add support for additional SoC
     implementations, and flexibility around power management for the
     serial-engine driver as well as probing the LLCC driver using
     custom hardware descriptions inside of the device itself.

   - Added support for the Samsung thermal management unit

   - A cleanup to the Tegra 'PMC' driver interfaces to remove legacy
     APIs and allow multiple PMC instances everywhere.

   - Updates to the TI SCI and KNAS drivers to improve suspend/resume
     support.

   - Minor driver changes for mediatek, xilinx, allwinner, aspeed,
     tegra, broadcom, amd, microchip and starfive specific drivers

   - Memory controller updates for Tegra and Renesas for additional SoC
     types and other improvements.

   - Firmware driver updates for Arm FF-A, SMCCC and SCMI interfaces, to
     update driver probing, object lifetimes and address minor bugs"
