Merge tag 'soc-drivers-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "Nothing particular important in the SoC driver updates, just the usual
  improvements to for drivers/soc and a couple of subsystems that don't
  fit anywhere else:

   - The largest set of updates is for Qualcomm SoC drivers, extending
     the set of supported features for additional SoCs in the QSEECOM,
     LLCC and socinfo drivers.a

   - The ti_sci firmware driver gains support for power managment

   - The drivers/reset subsystem sees a rework of the microchip sparx5
     and amlogic reset drivers to support additional chips, plus a few
     minor updates on other platforms

   - The SCMI firmware interface driver gains support for two protocol
     extensions, allowing more flexible use of the shared memory area
     and new DT binding properties for configurability.

   - Mediatek SoC drivers gain support for power managment on the MT8188
     SoC and a new driver for DVFS.

   - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
     and a few bugfixes

   - The Hisilicon Kunpeng HCCS driver gains support for configuring
     lanes through sysfs

  Finally, there are cleanups and minor fixes for drivers/{soc, bus,
  memory}, including changing back the .remove_new callback to .remove,
  as well as a few other updates for freescale (powerpc) soc drivers,
  NXP i.MX soc drivers, cznic turris platform driver, memory controller
  drviers, TI OMAP SoC drivers, and Tegra firmware drivers"
