Merge tag 'acpi-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki:
"These fix a frequency limit issue in the ACPI processor performance
library code, fix a few issues in the ACPICA code, improve Crystal
Cove support in the ACPI PMIC driver, fix string handling in the ACPI
battery driver, add IRQ override quirks for a few machines more, fix
other assorted problems and clean up code and documentation.
Specifics:
- Drop port I/O validation for some regions to avoid AML failures due
to rejections of legitimate port I/O writes (Mario Limonciello)
- Constify acpi_get_handle() pathname argument to allow its callers
to pass const pathnames to it (Sakari Ailus)
- Prevent acpi_ns_simple_repair() from crashing in some cases when
AE_AML_NO_RETURN_VALUE should be returned (Daniil Tatianin)
- Fix typo in CDAT DSMAS struct definition (Lukas Wunner)
- Drop an unnecessary (void *) conversion from the ACPI processor
driver (Zhou jie)
- Modify the ACPI processor performance library code to use the "no
limit" frequency QoS as appropriate and adjust the intel_pstate
driver accordingly (Rafael Wysocki)
- Add support for NBFT to the ACPI table parser (Stuart Hayes)
- Introduce list of known non-PNP devices to avoid enumerating some
of them as PNP devices (Rafael Wysocki)
- Add x86 ACPI paths to the ACPI entry in MAINTAINERS to allow
scripts to report the actual maintainers information (Rafael
Wysocki)
- Add two more entries to the ACPI IRQ override quirk list (Adam
Niederer, Werner Sembach)
- Add a pmic_i2c_address entry for Intel Bay Trail Crystal Cove to
allow intel_soc_pmic_exec_mipi_pmic_seq_element() to be used with
the Bay Trail Crystal Cove PMIC OpRegion driver (Hans de Goede)
- Add comments with DSDT power OpRegion field names to the ACPI PMIC
driver (Hans de Goede)
- Fix string termination handling in the ACPI battery driver (Armin
Wolf)
- Limit error type to 32-bit width in the ACPI APEI error injection
code (Shuai Xue)
- Fix Lenovo Ideapad Z570 DMI match in the ACPI backlight driver
(Hans de Goede)
- Silence missing prototype warnings in some places in the
ACPI-related code (Ammar Faizi)
- Make kobj_type structures used in the ACPI code constant (Thomas
Weißschuh)
- Correct spelling in firmware-guide/ACPI (Randy Dunlap)
- Clarify the meaning of Explicit and Implicit in the _DSD GPIO
properties documentation (Andy Shevchenko)
- Fix some kernel-doc comments in the ACPI CPPC library code (Yang
Li)"
