Merge tag 'acpi-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and PNP updates from Rafael Wysocki:
"These include new code (for instance, support for the FFH address
space type and support for new firmware data structures in ACPICA),
some new quirks (mostly related to backlight handling and I2C
enumeration), a number of fixes and a fair amount of cleanups all
over.
Specifics:
- Update the ACPICA code in the kernel to the 20221020 upstream
version and fix a couple of issues in it:
- Make acpi_ex_load_op() match upstream implementation (Rafael
Wysocki)
- Add support for loong_arch-specific APICs in MADT (Huacai Chen)
- Add support for fixed PCIe wake event (Huacai Chen)
- Add EBDA pointer sanity checks (Vit Kabele)
- Avoid accessing VGA memory when EBDA < 1KiB (Vit Kabele)
- Add CCEL table support to both compiler/disassembler (Kuppuswamy
Sathyanarayanan)
- Add a couple of new UUIDs to the known UUID list (Bob Moore)
- Add support for FFH Opregion special context data (Sudeep
Holla)
- Improve warning message for "invalid ACPI name" (Bob Moore)
- Add support for CXL 3.0 structures (CXIMS & RDPAS) in the CEDT
table (Alison Schofield)
- Prepare IORT support for revision E.e (Robin Murphy)
- Finish support for the CDAT table (Bob Moore)
- Fix error code path in acpi_ds_call_control_method() (Rafael
Wysocki)
- Fix use-after-free in acpi_ut_copy_ipackage_to_ipackage() (Li
Zetao)
- Update the version of the ACPICA code in the kernel (Bob Moore)
- Use ZERO_PAGE(0) instead of empty_zero_page in the ACPI device
enumeration code (Giulio Benetti)
- Change the return type of the ACPI driver remove callback to void
and update its users accordingly (Dawei Li)
- Add general support for FFH address space type and implement the
low- level part of it for ARM64 (Sudeep Holla)
- Fix stale comments in the ACPI tables parsing code and make it
print more messages related to MADT (Hanjun Guo, Huacai Chen)
- Replace invocations of generic library functions with more kernel-
specific counterparts in the ACPI sysfs interface (Christophe
JAILLET, Xu Panda)
- Print full name paths of ACPI power resource objects during
enumeration (Kane Chen)
- Eliminate a compiler warning regarding a missing function prototype
in the ACPI power management code (Sudeep Holla)
- Fix and clean up the ACPI processor driver (Rafael Wysocki, Li
Zhong, Colin Ian King, Sudeep Holla)
- Add quirk for the HP Pavilion Gaming 15-cx0041ur to the ACPI EC
driver (Mia Kanashi)
- Add some mew ACPI backlight handling quirks and update some
existing ones (Hans de Goede)
- Make the ACPI backlight driver prefer the native backlight control
over vendor backlight control when possible (Hans de Goede)
- Drop unsetting ACPI APEI driver data on remove (Uwe Kleine-König)
- Use xchg_release() instead of cmpxchg() for updating new GHES cache
slots (Ard Biesheuvel)
- Clean up the ACPI APEI code (Sudeep Holla, Christophe JAILLET, Jay
Lu)
- Add new I2C device enumeration quirks for Medion Lifetab S10346 and
Lenovo Yoga Tab 3 Pro (YT3-X90F) (Hans de Goede)
- Make the ACPI battery driver notify user space about adding new
battery hooks and removing the existing ones (Armin Wolf)
- Modify the pfr_update and pfr_telemetry drivers to use ACPI_FREE()
for freeing acpi_object structures to help diagnostics (Wang
ShaoBo)
- Make the ACPI fan driver use sysfs_emit_at() in its sysfs interface
code (ye xingchen)
- Fix the _FIF package extraction failure handling in the ACPI fan
driver (Hanjun Guo)
- Fix the PCC mailbox handling error code path (Huisong Li)
- Avoid using PCC Opregions if there is no platform interrupt
allocated for this purpose (Huisong Li)
- Use sysfs_emit() instead of scnprintf() in the ACPI PAD driver and
CPPC library (ye xingchen)
- Fix some kernel-doc issues in the ACPI GSI processing code
(Xiongfeng Wang)
- Fix name memory leak in pnp_alloc_dev() (Yang Yingliang)
- Do not disable PNP devices on suspend when they cannot be
re-enabled on resume (Hans de Goede)
- Clean up the ACPI thermal driver a bit (Rafael Wysocki)"
