Pull ACPI updates from Rafael Wysocki:
 "From the new features standpoint, the most significant change here is
  the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
  device enumeration code that will allow MIPI cameras to be enumerated
  through the platform firmware on systems using ACPI.

  Also significant is the switch-over to threaded interrupt handlers for
  the ACPI SCI and the dedicated EC interrupt (on systems where the
  former is not used) which essentially allows all ACPI code to run with
  local interrupts enabled. That should improve responsiveness
  significantly on systems where multiple GPEs are enabled and the
  handling of one SCI involves many I/O address space accesses which
  previously had to be carried out in one go with disabled interrupts on
  the local CPU.

  Apart from the above, the ACPI thermal zone driver will use the
  Thermal fast Sampling Period (_TFP) object if available, which should
  allow temperature changes to be followed more accurately on some
  systems, the ACPI Notify () handlers can run on all CPUs (not just on
  CPU0), which should generally speed up the processing of events
  signaled through the ACPI SCI, and the ACPI power button driver will
  trigger wakeup key events via the input subsystem (on systems where it
  is a system wakeup device)

  In addition to that, there are the usual bunch of fixes and cleanups.

  Specifics:

   - Add CSI-2 and DisCo for Imaging support to the ACPI device
     enumeration code (Sakari Ailus, Rafael J. Wysocki)

   - Adjust the cpufreq thermal reduction algorithm in the ACPI
     processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
     Bergmann)

   - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)

   - Switch over ACPI to using a threaded interrupt handler for the SCI
     (Rafael J. Wysocki)

   - Allow ACPI Notify () handlers to run on all CPUs and clean up the
     ACPI interface for deferred events processing (Rafael J. Wysocki)

   - Switch over the ACPI EC driver to using a threaded handler for the
     dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)

   - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
     to keep local interrupts on (Rafael J. Wysocki)

   - Adjust the USB4 _OSC handshake to correctly handle cases in which
     certain types of OS control are denied by the platform (Mika
     Westerberg)

   - Correct and clean up the generic function for parsing ACPI
     data-only tables with array structure (Yuntao Wang)

   - Modify acpi_dev_uid_match() to support different types of its
     second argument and adjust its users accordingly (Raag Jadav)

   - Clean up code related to acpi_evaluate_reference() and ACPI device
     lists (Rafael J. Wysocki)

   - Use generic ACPI helpers for evaluating trip point temperature
     objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
     Bergmann)

   - Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
     zone driver (Jeff Brasen)

   - Modify the ACPI LPIT table handling code to avoid u32
     multiplication overflows in state residency computations (Nikita
     Kiryushin)

   - Drop an unused helper function from the ACPI backlight (video)
     driver and add a clarifying comment to it (Hans de Goede)

   - Update the ACPI backlight driver to avoid using uninitialized
     memory in some cases (Nikita Kiryushin)

   - Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
     Qiu)

   - Add support for vendor-defined error types to the ACPI APEI error
     injection code (Avadhut Naik)

   - Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
     memory failure events, so they are handled differently from the
     asynchronous ones (Shuai Xue)

   - Fix NULL pointer dereference check in the ACPI extlog driver
     (Prarit Bhargava)

   - Adjust the ACPI extlog driver to clear the Extended Error Log
     status when RAS_CEC handled the error (Tony Luck)

   - Add IRQ override quirks for some Infinity laptops and for TongFang
     GMxXGxx (David McFarland, Hans de Goede)

   - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
     not the same as one of the real pxm values (Yuntao Wang)

   - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
     driver so as to prevent miscalculation of the values in the clock
     divider (Andy Shevchenko)

   - Adjust comments in the ACPI watchdog driver to prevent kernel-doc
     from complaining during documentation builds (Randy Dunlap)

   - Make the ACPI button driver send wakeup key events to user space in
     addition to power button events on systems that can be woken up by
     the power button (Ken Xue)

   - Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
     structure field (Dmitry Antipov)"
