Merge tag 'acpi-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These update the ACPICA code in the kernel to the 20210604 upstream revision, add preliminary support for the Platform Runtime Mechanism (PRM), address issues related to the handling of device dependencies in the ACPI device eunmeration code, improve the tracking of ACPI power resource states, improve the ACPI support for suspend-to-idle on AMD systems, continue the unification of message printing in the ACPI code, address assorted issues and clean up the code in a number of places. Specifics: - Update ACPICA code in the kernel to upstrea revision 20210604 including the following changes: - Add defines for the CXL Host Bridge Structureand and add the CFMWS structure definition to CEDT (Alison Schofield). - iASL: Finish support for the IVRS ACPI table (Bob Moore). - iASL: Add support for the SVKL table (Bob Moore). - iASL: Add full support for RGRT ACPI table (Bob Moore). - iASL: Add support for the BDAT ACPI table (Bob Moore). - iASL: add disassembler support for PRMT (Erik Kaneda). - Fix memory leak caused by _CID repair function (Erik Kaneda). - Add support for PlatformRtMechanism OpRegion (Erik Kaneda). - Add PRMT module header to facilitate parsing (Erik Kaneda). - Add _PLD panel positions (Fabian Wüthrich). - MADT: add Multiprocessor Wakeup Mailbox Structure and the SVKL table headers (Kuppuswamy Sathyanarayanan). - Use ACPI_FALLTHROUGH (Wei Ming Chen). - Add preliminary support for the Platform Runtime Mechanism (PRM) to allow the AML interpreter to call PRM functions (Erik Kaneda). - Address some issues related to the handling of device dependencies reported by _DEP in the ACPI device enumeration code and clean up some related pieces of it (Rafael Wysocki). - Improve the tracking of states of ACPI power resources (Rafael Wysocki). - Improve ACPI support for suspend-to-idle on AMD systems (Alex Deucher, Mario Limonciello, Pratik Vishwakarma). - Continue the unification and cleanup of message printing in the ACPI code (Hanjun Guo, Heiner Kallweit). - Fix possible buffer overrun issue with the description_show() sysfs attribute method (Krzysztof Wilczyński). - Improve the acpi_mask_gpe kernel command line parameter handling and clean up the core ACPI code related to sysfs (Andy Shevchenko, Baokun Li, Clayton Casciato). - Postpone bringing devices in the general ACPI PM domain to D0 during resume from system-wide suspend until they are really needed (Dmitry Torokhov). - Make the ACPI processor driver fix up C-state latency if not ordered (Mario Limonciello). - Add support for identifying devices depening on the given one that are not its direct descendants with the help of _DEP (Daniel Scally). - Extend the checks related to ACPI IRQ overrides on x86 in order to avoid false-positives (Hui Wang). - Add battery DPTF participant for Intel SoCs (Sumeet Pawnikar). - Rearrange the ACPI fan driver and device power management code to use a common list of device IDs (Rafael Wysocki). - Fix clang CFI violation in the ACPI BGRT table parsing code and clean it up (Nathan Chancellor). - Add GPE-related quirks for some laptops to the EC driver (Chris Chiu, Zhang Rui). - Make the ACPI PPTT table parsing code populate the cache-id value if present in the firmware (James Morse). - Remove redundant clearing of context->ret.pointer from acpi_run_osc() (Hans de Goede). - Add missing acpi_put_table() in acpi_init_fpdt() (Jing Xiangfeng). - Make ACPI APEI handle ARM Processor Error CPER records like Memory Error ones to avoid user space task lockups (Xiaofei Tan). - Stop warning about disabled ACPI in APEI (Jon Hunter). - Fix fall-through warning for Clang in the SBSHC driver (Gustavo A. R. Silva). - Add custom DSDT file as Makefile prerequisite (Richard Fitzgerald). - Initialize local variable to avoid garbage being returned (Colin Ian King). - Simplify assorted pieces of code, address assorted coding style and documentation issues and comment typos (Baokun Li, Christophe JAILLET, Clayton Casciato, Liu Shixin, Shaokun Zhang, Wei Yongjun, Yang Li, Zhen Lei)" * tag 'acpi-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (97 commits) ACPI: PM: postpone bringing devices to D0 unless we need them ACPI: tables: Add custom DSDT file as makefile prerequisite ACPI: bgrt: Use sysfs_emit ACPI: bgrt: Fix CFI violation ACPI: EC: trust DSDT GPE for certain HP laptop ACPI: scan: Simplify acpi_table_events_fn() ACPI: PM: Adjust behavior for field problems on AMD systems ACPI: PM: s2idle: Add support for new Microsoft UUID ACPI: PM: s2idle: Add support for multiple func mask ACPI: PM: s2idle: Refactor common code ACPI: PM: s2idle: Use correct revision id ACPI: sysfs: Remove tailing return statement in void function ACPI: sysfs: Use __ATTR_RO() and __ATTR_RW() macros ACPI: sysfs: Sort headers alphabetically ACPI: sysfs: Refactor param_get_trace_state() to drop dead code ACPI: sysfs: Unify pattern of memory allocations ACPI: sysfs: Allow bitmap list to be supplied to acpi_mask_gpe ACPI: sysfs: Make sparse happy about address space in use ACPI: scan: Fix race related to dropping dependencies ACPI: scan: Reorganize acpi_device_add() ...
