Merge tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32,
  samsung, imx, zynq and amlogic platoforms are fairly small maintenance
  changes, either addressing minor mistakes or enabling additional
  hardware.

  The qualcomm platform changes add a number of features and are larger
  than the other ones combined, introducing the use of linux/cleanup.h
  across several drivers, adding support for Snapdragon X1E and other
  SoCs in platform drivers, a new "protection domain mapper" driver, and
  a "shared memory bridge" driver.

  The cznic "turris omnia" router based on Marvell Armada gets a
  platform driver that talks to the board specific microcontroller.

  The reset and cache subsystems get a few minor updates to SoC specific
  drivers, while the ff-a, scmi and optee firmware drivers get some code
  refactoring and new features"
