Merge tag 'acpi-4.18-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 20180508 upstream revision and make it support the RT patch, add CPPC v3 support to the ACPI CPPC library, add a WDAT-based watchdog quirk to prevent clashes with the RTC, add quirks to the ACPI AC and battery drivers, and update the ACPI SoC drivers. Specifics: - Update the ACPICA code in the kernel to the 20180508 upstream revision including: * iASL -tc option enhancement (Bob Moore). * Debugger improvements (Bob Moore). * Support for tables larger than 1 MB in acpidump/acpixtract (Bob Moore). * Minor fixes and cleanups (Colin Ian King, Toomas Soome). - Make the ACPICA code in the kernel support the RT patch (Sebastian Andrzej Siewior, Steven Rostedt). - Add a kmemleak annotation to the ACPICA code (Larry Finger). - Add CPPC v3 support to the ACPI CPPC library and fix two issues related to CPPC (Prashanth Prakash, Al Stone). - Add an ACPI WDAT-based watchdog quirk to prefer iTCO_wdt on systems where WDAT clashes with the RTC SRAM (Mika Westerberg). - Add some quirks to the ACPI AC and battery drivers (Carlo Caione, Hans de Goede). - Update the ACPI SoC drivers for Intel (LPSS) and AMD (APD) platforms (Akshu Agrawal, Hans de Goede). - Fix up some assorted minor issues (Al Stone, Laszlo Toth, Mathieu Malaterre)" * tag 'acpi-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) ACPICA: Mark acpi_ut_create_internal_object_dbg() memory allocations as non-leaks ACPI / watchdog: Prefer iTCO_wdt always when WDAT table uses RTC SRAM mailbox: PCC: erroneous error message when parsing ACPI PCCT ACPICA: Update version to 20180508 ACPICA: acpidump/acpixtract: Support for tables larger than 1MB ACPI: APD: Add AMD misc clock handler support clk: x86: Add ST oscout platform clock ACPICA: Update version to 20180427 ACPICA: Debugger: Removed direct support for EC address space in "Test Objects" ACPICA: Debugger: Add Package support for "test objects" command ACPICA: Improve error messages for the namespace root node ACPICA: Fix potential infinite loop in acpi_rs_dump_byte_list ACPICA: vsnprintf: this statement may fall through ACPICA: Tables: Fix spelling mistake in comment ACPICA: iASL: Enhance the -tc option (create AML hex file in C) ACPI: Add missing prototype_for arch_post_acpi_subsys_init() ACPI / tables: improve comments regarding acpi_parse_entries_array() ACPICA: Convert acpi_gbl_hardware lock back to an acpi_raw_spinlock ACPICA: provide abstraction for raw_spinlock_t ACPI / CPPC: Fix invalid PCC channel status errors ...
