Merge tag 'acpi-5.13-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 most recent upstream revision including (but not limited to) new material introduced in the 6.4 version of the spec, update message printing in the ACPI-related code, address a few issues and clean up code in a number of places. Specifics: - Update ACPICA code in the kernel to upstream revision 20210331 including the following changes: * Add parsing for IVRS IVHD 40h and device entry F0h (Alexander Monakov). * Add new CEDT table for CXL 2.0 and iASL support for it (Ben Widawsky, Bob Moore). * NFIT: add Location Cookie field (Bob Moore). * HMAT: add new fields/flags (Bob Moore). * Add new flags in SRAT (Bob Moore). * PMTT: add new fields/structures (Bob Moore). * Add CSI2Bus resource template (Bob Moore). * iASL: Decode subtable type field for VIOT (Bob Moore). * Fix various typos and spelling mistakes (Colin Ian King). * Add new predefined objects _BPC, _BPS, and _BPT (Erik Kaneda). * Add USB4 capabilities UUID (Erik Kaneda). * Add CXL ACPI device ID and _CBR object (Erik Kaneda). * MADT: add Multiprocessor Wakeup Structure (Erik Kaneda). * PCCT: add support for subtable type 5 (Erik Kaneda). * PPTT: add new version of subtable type 1 (Erik Kaneda). * Add SDEV secure access components (Erik Kaneda). * Add support for PHAT table (Erik Kaneda). * iASL: Add definitions for the VIOT table (Jean-Philippe Brucker). * acpisrc: Add missing conversion for VIOT support (Jean-Philippe Brucker). * IORT: Updates for revision E.b (Shameer Kolothum). - Rearrange message printing in ACPI-related code to avoid using the ACPICA's internal message printing macros outside ACPICA and do some related code cleanups (Rafael Wysocki). - Modify the device enumeration code to turn off all of the unused ACPI power resources at the end (Rafael Wysocki). - Change the ACPI power resources handling code to turn off unused ACPI power resources without checking their status which should not be necessary by the spec (Rafael Wysocki). - Add empty stubs for CPPC-related functions to be used when CONFIG_ACPI_CPPC_LIB is not set (Rafael Wysocki). - Simplify device enumeration code (Rafael Wysocki). - Change device enumeration code to use match_string() for string matching (Andy Shevchenko). - Modify irqresource_disabled() to retain the resouce flags that have been set already (Angela Czubak). - Add native backlight whitelist entry for GA401/GA502/GA503 (Luke Jones). - Modify the ACPI backlight driver to let the native backlight handling take over on hardware-reduced systems (Hans de Goede). - Introduce acpi_dev_get() and switch over the ACPI core code to using it (Andy Shevchenko). - Use kobj_attribute as callback argument instead of a local struct type in the CPPC linrary code (Nathan Chancellor). - Drop unneeded initializatio of a static variable from the ACPI processor driver (Tian Tao). - Drop unnecessary local variable assignment from the ACPI APEI code (Colin Ian King). - Document for_each_acpi_dev_match() macro (Andy Shevchenko). - Address assorted coding style issues in multiple places (Xiaofei Tan). - Capitalize TLAs in a few comments (Andy Shevchenko). - Correct assorted typos in comments (Tom Saeger)" * tag 'acpi-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (68 commits) ACPI: video: use native backlight for GA401/GA502/GA503 ACPI: APEI: remove redundant assignment to variable rc ACPI: utils: Capitalize abbreviations in the comments ACPI: utils: Document for_each_acpi_dev_match() macro ACPI: bus: Introduce acpi_dev_get() and reuse it in ACPI code ACPI: scan: Utilize match_string() API resource: Prevent irqresource_disabled() from erasing flags ACPI: CPPC: Replace cppc_attr with kobj_attribute ACPI: scan: Call acpi_get_object_info() from acpi_set_pnp_ids() ACPI: scan: Drop sta argument from acpi_init_device_object() ACPI: scan: Drop sta argument from acpi_add_single_object() ACPI: scan: Rearrange checks in acpi_bus_check_add() ACPI: scan: Fold acpi_bus_type_and_status() into its caller ACPI: video: Check LCD flag on ACPI-reduced-hardware devices ACPI: utils: Add acpi_reduced_hardware() helper ACPI: dock: fix some coding style issues ACPI: sysfs: fix some coding style issues ACPI: PM: add a missed blank line after declarations ACPI: custom_method: fix a coding style issue ACPI: CPPC: fix some coding style issues ...
