Merge tag 'soc-drivers-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "Lots of platform specific updates for Qualcomm SoCs, including a new
  TEE subsystem driver for the Qualcomm QTEE firmware interface.

  Added support for the Apple A11 SoC in drivers that are shared with
  the M1/M2 series, among more updates for those.

  Smaller platform specific driver updates for Renesas, ASpeed,
  Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale
  SoCs.

  Driver updates in the cache controller, memory controller and reset
  controller subsystems.

  SCMI firmware updates to add more features and improve robustness.
  This includes support for having multiple SCMI providers in a single
  system.

  TEE subsystem support for protected DMA-bufs, allowing hardware to
  access memory areas that managed by the kernel but remain inaccessible
  from the CPU in EL1/EL0"
