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"

A few more Qualcomm driver updates for v6.13

Make the Adreno driver invoke the SMMU aperture setup firmware function,
which is required to allow the GPU to manage per-process page tables in
some firmware versions - as an example Rb3Gen2 has no GPU without this.

Add X1E Devkit to the list of devices that has functional EFI variable
access through the uefisecapp.

Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver,
as this only applies to a single platform, and introduce support for
QCS8300, QCS615, SAR2130P, and SAR1130P.

Lastly, add IPQ5424 and IPQ5404 to the Qualcomm socinfo driver.

Qualcomm driver fixes for v6.12

The Qualcomm EDAC driver's configuration of interrupts is made optional,
to avoid violating security constriants on X Elite platform .

The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE,
is corrected to handle the case where firmware successfully returns that
the interface isn't supported.

The GLINK driver and the PMIC GLINK interface is updated to handle
buffer allocation issues during initialization of the communication
channel.

Allocation error handling in the socinfo dirver is corrected, and then
the fix is corrected.

Cancelling an rx command is signalled using bit 14 of the rx DMA status
register and not bit 11.

This bit is currently unused, but this error becomes apparent, for
example, when tracing the status register when closing the port.

On most modern qualcomm SoCs, the configuration necessary to enable the
Tag/Data RAM related irqs being propagated to the SoC irq controller is
already done in firmware (in DSF or 'DDR System Firmware')

On some like the x1e80100, these registers aren't even accesible to the
kernel causing a crash when edac device is probed.

Hence, make the irq configuration optional in the driver and mark x1e80100
as the SoC on which this should be avoided.

Pull tty / serial driver updates from Greg KH:
 "Here is the "big" set of tty/serial driver updates for 6.12-rc1.

  Nothing major in here, just nice forward progress in the slow cleanup
  of the serial apis, and lots of other driver updates and fixes.

  Included in here are:

   - serial api updates from Jiri to make things more uniform and sane

   - 8250_platform driver cleanups

   - samsung serial driver fixes and updates

   - qcom-geni serial driver fixes from Johan for the bizarre UART
     engine that that chip seems to have. Hopefully it's in a better
     state now, but hardware designers still seem to come up with more
     ways to make broken UARTS 40+ years after this all should have
     finished.

   - sc16is7xx driver updates

   - omap 8250 driver updates

   - 8250_bcm2835aux driver updates

   - a few new serial driver bindings added

   - other serial minor driver updates

  All of these have been in linux-next for a long time with no reported
  problems"

For UART devices the M_GP_LENGTH is the TX word count. For other
devices this is the transaction word count.

For UART devices the S_GP_LENGTH is the RX word count.

The IRQ_EN set/clear registers allow you to set or clear bits in the
IRQ_EN register without needing a read-modify-write.

<title>soc: qcom: pmic_glink: Fix race during initialization</title>

As pointed out by Stephen Boyd it is possible that during initialization
of the pmic_glink child drivers, the protection-domain notifiers fires,
and the associated work is scheduled, before the client registration
returns and as a result the local "client" pointer has been initialized.

The outcome of this is a NULL pointer dereference as the "client"
pointer is blindly dereferenced.

Timeline provided by Stephen:
 CPU0                               CPU1
 ----                               ----
 ucsi-&gt;client = NULL;
 devm_pmic_glink_register_client()
  client-&gt;pdr_notify(client-&gt;priv, pg-&gt;client_state)
   pmic_glink_ucsi_pdr_notify()
    schedule_work(&amp;ucsi-&gt;register_work)
    &lt;schedule away&gt;
                                    pmic_glink_ucsi_register()
                                     ucsi_register()
                                      pmic_glink_ucsi_read_version()
                                       pmic_glink_ucsi_read()
                                        pmic_glink_ucsi_read()
                                         pmic_glink_send(ucsi-&gt;client)
                                         &lt;client is NULL BAD&gt;
 ucsi-&gt;client = client // Too late!

This code is identical across the altmode, battery manager and usci
child drivers.

Resolve this by splitting the allocation of the "client" object and the
registration thereof into two operations.

This only happens if the protection domain registry is populated at the
time of registration, which by the introduction of commit '1ebcde047c54
("soc: qcom: add pd-mapper implementation")' became much more likely.
