Pull tty driver fix from Greg KH:
 "Here is a single driver fix for the qcom_geni_serial driver. It has
  been in my tree for weeks, but missed being sent to you for 6.17-final
  due to travel on my side.

  This fixes a reported regression for this driver that prevents 6.17
  from working properly on this platform.

  It has been in linux-next for many weeks with no reported issues"

 "Here are some small updates for tty/serial drivers for 6.18-rc1.

  Not many changes overall, just the usual:

   - abi cleanups and reworking of the tty functions by Jiri by adding
     console lock guard logic

   - 8250_platform driver updates

   - qcom-geni driver updates

   - other minor serial driver updates

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"

More Qualcomm device driver updates for v6.18

Introduce support for loading firmware into the QUP serial engines from
Linux, which allows deferring selection of which protocol (uart, i2c,
spi, etc) a given SE should have until the OS loads.

Also introduce the "object invoke" interface in the SCM driver, to
provide interface to the Qualcomm TEE driver.

The issue was reported on 12th of August and was ignored by author of
commits introducing issue for two weeks.  Only after complaining author
produced a fix which did not work, so if original commits cannot be
reliably fixed for 5 weeks, they obviously are buggy and need to be
dropped.

Microchip ARM64 SoC updates for v6.18:

This update includes:
- basic infrastructure support for Microchip LAN969x SoC
- SoC ARCH symbols (existing SparX-5, new LAN969x) under the
  ARCH_MICROCHIP hidden symbol (already in use by AT91 in 6.17)
- addition of that new symbol for drivers that are shared by
  Microchip SoC-s now and in the future
