Merge tag 'acpi-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These update the ACPICA kernel code to upstream revision 20210730, clean up the ACPI companion binding code, optimize the I2C handling in the XPower PMIC driver, add 16550-compatible Serial Port Subtype support to the SPCR parsing code, add a few LoongArch support bits, add a ne quirk to the button driver, add new PCH FIVR methods to the DPTF code, replace deprecated CPU-hotplug functions in the processor driver, improve the acpi_os_map_memory() handling on non-x86 and do some assorted cleanups. Specifics: - Update ACPICA code in the kernel to upstream revision 20210730 including the following changes: - Add support for the AEST table (data compiler) to iASL (Bob Moore) - Fix an if statement (add parens) (Bob Moore) - Drop trailing semicolon from some macros (Bob Moore) - Fix compilation of WPBT table with no command-line arguments in iASL (Bob Moore) - Add method name "_DIS" for use with aslmethod.c (Bob Moore) - Add new DBG2 Serial Port Subtypes (Marcin Wojtas) - Add new PCH FIVR methods to the DPTF code (Srinivas Pandruvada) - Add support for the new 16550-compatible Serial Port Subtype to the SPCR table parsing code (Marcin Wojtas) - Add DMI quirk for Lenovo Yoga 9 (14INTL5) to the ACPI button driver (Ulrich Huber) - Add LoongArch support for ACPI_PROCESSOR/ACPI_NUMA (Huacai Chen) - Add memory semantics to acpi_os_map_memory() (Lorenzo Pieralisi) - Replace deprecated CPU-hotplug functions in the ACPI processor driver (Sebastian Andrzej Siewior) - Optimize I2C-bus handling in the XPower PMIC driver (Hans de Goede) - Make platform-profile catch profile changes initiated by user space and notify user processes of them (Hans de Goede) - Clean up the ACPI companion binding and unbinding code and update debug messaging in the ACPI power resources code (Rafael Wysocki) - Clean up a couple of code pieces related to configfs (Andy Shevchenko) - Rearrange the FPDT table parsing code to avoid printing warning messages for reserved record types (Adrian Huang)" * tag 'acpi-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (27 commits) ACPI: power: Drop name from struct acpi_power_resource ACPI: power: Use acpi_handle_debug() to print debug messages ACPI: tables: FPDT: Do not print FW_BUG message if record types are reserved ACPI: button: Add DMI quirk for Lenovo Yoga 9 (14INTL5) ACPI: Add memory semantics to acpi_os_map_memory() ACPI: SPCR: Add support for the new 16550-compatible Serial Port Subtype ACPI: platform-profile: call sysfs_notify() from platform_profile_store() ACPICA: Update version to 20210730 ACPICA: Add method name "_DIS" For use with aslmethod.c ACPICA: iASL: Fix for WPBT table with no command-line arguments ACPICA: Headers: Add new DBG2 Serial Port Subtypes ACPICA: Macros should not use a trailing semicolon ACPICA: Fix an if statement (add parens) ACPICA: iASL: Add support for the AEST table (data compiler) ACPI: processor: Replace deprecated CPU-hotplug functions ACPI: DPTF: Add new PCH FIVR methods ACPI: configfs: Make get_header() to return error pointer ACPI: configfs: Use sysfs_emit() in "show" functions driver core: Split device_platform_notify() software nodes: Split software_node_notify() ...
