Merge tag 'acpi-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "ACPI and PNP updates for 6.1-rc1. These rearrange the ACPI device object initialization code (to get rid of a redundant parent pointer from struct acpi_device among other things), unify the _UID handling, drop support for some _OSI strings that should not be necessary any more, add new IDs to support more hardware and some more quirks, fix a few issues and clean up code all over. Specifics: - Reimplement acpi_get_pci_dev() using the list of physical devices associated with the given ACPI device object (Rafael Wysocki) - Rename ACPI device object reference counting functions (Rafael Wysocki) - Rearrange ACPI device object initialization code (Rafael Wysocki) - Drop parent field from struct acpi_device (Rafael Wysocki) - Extend the the int3472-tps68470 driver to support multiple consumers of a single TPS68470 along with the requisite framework-level support (Daniel Scally) - Filter out non-memory resources in is_memory(), add a helper function to find all memory type resources of an ACPI device object and use that function in 3 places (Heikki Krogerus) - Add IRQ override quirks for Asus Vivobook K3402ZA/K3502ZA and ASUS model S5402ZA (Tamim Khan, Kellen Renshaw) - Fix acpi_dev_state_d0() kerneldoc (Sakari Ailus) - Fix up suspend-to-idle support on ASUS Rembrandt laptops (Mario Limonciello) - Clean up ACPI platform devices support code (Andy Shevchenko, John Garry) - Clean up ACPI bus management code (Andy Shevchenko, ye xingchen) - Add support for multiple DMA windows with different offsets to the ACPI device enumeration code and use it on LoongArch (Jianmin Lv) - Clean up the ACPI LPSS (Intel SoC) driver (Andy Shevchenko) - Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable (Mario Limonciello) - Drop unused dev_fmt() and redundant 'HMAT' prefix from the HMAT parsing code (Liu Shixin) - Make ACPI FPDT parsing code avoid calling acpi_os_map_memory() on invalid physical addresses (Hans de Goede) - Silence missing-declarations warning related to Apple device properties management (Lukas Wunner) - Disable frequency invariance in the CPPC library if registers used by cppc_get_perf_ctrs() are accessed via PCC (Jeremy Linton) - Add ACPI disabled check to acpi_cpc_valid() (Perry Yuan) - Fix Tx acknowledge in the PCC address space handler (Huisong Li) - Use wait_for_completion_timeout() for PCC mailbox operations (Huisong Li) - Release resources on PCC address space setup failure path (Rafael Mendonca) - Remove unneeded result variables from APEI code (ye xingchen) - Print total number of records found during BERT log parsing (Dmitry Monakhov) - Drop support for 3 _OSI strings that should not be necessary any more and update documentation on custom _OSI strings so that adding new ones is not encouraged any more (Mario Limonciello) - Drop unneeded result variable from ec_write() (ye xingchen) - Remove the leftover struct acpi_ac_bl from the ACPI AC driver (Hanjun Guo) - Reorder symbols to get rid of a few forward declarations in the ACPI fan driver (Uwe Kleine-König) - Add Toshiba Satellite/Portege Z830 ACPI backlight quirk (Arvid Norlander) - Add ARM DMA-330 controller to the supported list in the ACPI AMBA driver (Vijayenthiran Subramaniam) - Drop references to non-functional 01.org/linux-acpi web site from MAINTAINERS and Kconfig help texts (Rafael Wysocki) - Replace strlcpy() with unused retval with strscpy() in the ACPI support code (Wolfram Sang) - Do not initialize ret in main() in the pfrut utility (Shi junming) - Drop useless ACPI DSDT override documentation (Rafael Wysocki) - Fix a few typos and wording mistakes in the ACPI device enumeration documentation (Jean Delvare) - Introduce acpi_dev_uid_to_integer() to convert a _UID string into an integer value (Andy Shevchenko) - Use acpi_dev_uid_to_integer() in several places to unify _UID handling (Andy Shevchenko) - Drop unused pnpid32_to_pnpid() declaration from PNP code (Gaosheng Cui)" * tag 'acpi-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (79 commits) ACPI: LPSS: Deduplicate skipping device in acpi_lpss_create_device() ACPI: LPSS: Replace loop with first entry retrieval ACPI: x86: s2idle: Add another ID to s2idle_dmi_table ACPI: x86: s2idle: Fix a NULL pointer dereference MAINTAINERS: Drop records pointing to 01.org/linux-acpi ACPI: Kconfig: Drop link to https://01.org/linux-acpi ACPI: docs: Drop useless DSDT override documentation ACPI: DPTF: Drop stale link from Kconfig help ACPI: x86: s2idle: Add a quirk for ASUSTeK COMPUTER INC.
