Subject: [GIT PULL] ACPI updates for v5.20-rc1
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-5.20-rc1
with top-most commit 6352f3478a95cc413ecfee4fdb3300009fd3679a
Merge branches 'acpi-video', 'acpi-pci' and 'acpi-docs'
on top of commit e0dccc3b76fb35bb257b4118367a883073d7390e
Linux 5.19-rc8
to receive ACPI updates for 5.20-rc1.
These rework the handling of ACPI device objects to use the driver
core facilities for managing child ones instead of some questionable
home-grown ways without the requisite locking and reference counting,
clean up the EC driver, improve suspend-to-idle handling on x86, add
some systems to the ACPI backlight quirk list, fix some assorted
issues, clean up code and improve documentation.
Specifics:
- Use facilities provided by the driver core and some additional
helpers to handle the children of a given ACPI device object in
multiple places instead of using the children and node list heads in
struct acpi_device which is error prone (Rafael Wysocki).
- Fix ACPI-related device reference counting issue in the hisi_lpc bus
driver (Yang Yingliang).
- Drop the children and node list heads that are not needed any more
from struct acpi_device (Rafael Wysocki).
- Drop driver member from struct acpi_device (Uwe Kleine-König).
- Drop redundant check from acpi_device_remove() (Uwe Kleine-König).
- Prepare the CPPC library for handling backwards-compatible future
_CPC return package formats gracefully (Rafael Wysocki).
- Clean up the ACPI EC driver after previous changes in it (Hans
de Goede).
- Drop leftover acpi_processor_get_limit_info() declaration (Riwen
Lu).
- Split out thermal initialization from ACPI PSS (Riwen Lu).
- Annotate more functions in the ACPI CPU idle driver to live in the
cpuidle section (Guilherme G. Piccoli).
- Fix _EINJ vs "special purpose" EFI memory regions (Dan Williams).
- Implement a better fix to avoid spamming the console with old error
logs (Tony Luck).
- Fix typo in a comment in the APEI code (Xiang wangx).
- Save NVS memory during transitions into S3 on Lenovo G40-45 (Manyi
Li).
- Add support for upcoming AMD uPEP device ID AMDI008 to the ACPI
suspend-to-idle driver for x86 platforms (Shyam Sundar S K).
- Clean up checks related to the ACPI_FADT_LOW_POWER_S0 platform flag
in the LPIT table driver and the suspend-to-idle driver for x86
platforms (Rafael Wysocki).
- Print information messages regarding declared LPS0 idle support in
the platform firmware (Rafael Wysocki).
- Fix missing check in register_device_clock() in the ACPI driver for
Intel SoCs (huhai).
- Fix ACS setup in the VIOT table parser (Eric Auger).
- Skip IRQ override on AMD Zen platforms where it's harmful (Chuanhong
Guo).
- Use native backlight on Dell Inspiron N4010 (Hans de Goede).
- Use native backlight on some TongFang devices (Werner Sembach).
- Drop X86 dependency from the ACPI backlight driver Kconfig (Riwen
Lu).
- Shorten the quirk list in the ACPI backlight driver by identifying
Clevo by board_name only (Werner Sembach).
- Remove useless NULL pointer checks from 2 ACPI PCI link management
functions (Andrey Strachuk).
- Fix obsolete example in the ACPI EINJ documentation (Qifu Zhang).
- Update links and references to _DSD-related documents (Sudeep
Holla).
Thanks!
