Merge tag 'acpi-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "These revert two ACPICA commits that are not needed any more, rework the property graphs support in ACPI to be more aligned with the analogous DT code, add some new quirks and remove one that isn't needed any more, add a special platform driver to enumerate multiple I2C devices hooked up to the same device object in the ACPI tables and update the battery and button drivers. Specifics: - Revert two ACPICA commits that are not needed any more (Erik Schmauss). - Rework property graph support in the ACPI device properties framework to make it behave more like the analogous DT code and update the documentation of it (Sakari Ailus). - Change the default ACPI device status after initialization to ACPI_STA_DEFAULT instead of 0 (Hans de Goede). - Add a special platform driver for enumerating multiple I2C devices hooked up to the same object in the ACPI tables (Hans de Goede). - Fix the ACPI battery driver to avoid reporting full capacity on systems without support for that and clean it up (Hans de Goede, Dmitry Rozhkov, Lucas Rangit Magasweran). - Add two system wakeup quirks to the ACPI EC driver (Aaron Ma, Mika Westerberg). - Add the touchscreen on Dell Venue Pro 7139 to the list of "always present" devices to make it work (Tristian Celestin). - Revert a special tables handling quirk for Dell XPS 9570 and Precision M5530 which is not needed any more (Kai Heng Feng). - Add support for a new OEM _OSI string to allow system vendors to work around issues with NVidia HDMI audio (Alex Hung). - Prevent the ACPI button driver from reporting excessive system wakeup events and clean it up (Ravi Chandra Sadineni, Randy Dunlap). - Clean up two minor code style issues in the ACPI core and GHES handling on ARM64 (Dongjiu Geng, John Garry, Tom Todd)" * tag 'acpi-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (34 commits) platform/x86: Add ACPI i2c-multi-instantiate pseudo driver ACPI / x86: utils: Remove status workaround from acpi_device_always_present() ACPI / scan: Create platform device for fwnodes with multiple i2c devices ACPI / scan: Initialize status to ACPI_STA_DEFAULT ACPI / EC: Add another entry for Thinkpad X1 Carbon 6th ACPI: bus: Fix a pointer coding style issue arm64 / ACPI: clean the additional checks before calling ghes_notify_sea() ACPI / scan: Add static attribute to indirect_io_hosts[] ACPI / battery: Do not export energy_full[_design] on devices without full_charge_capacity ACPI / EC: Use ec_no_wakeup on ThinkPad X1 Yoga 3rd ACPI / battery: get rid of negations in conditions ACPI / battery: use specialized print macros ACPI / battery: reorder headers alphabetically ACPI / battery: drop inclusion of init.h ACPI: battery: remove redundant old_present check on insertion ACPI: property: graph: Update graph documentation to use generic references ACPI: property: graph: Improve graph documentation for port/ep numbering ACPI: property: graph: Fix graph documentation ACPI: property: Update documentation for hierarchical data extension 1.1 ACPI: property: Document key numbering for hierarchical data extension refs ...
