Merge tag 'acpi-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI updates from Rafael Wysocki: "First off, the ACPICA code in the kernel is updated to upstream revision 20160831 that brings in a few bug fixes and cleanups. In particular, it is possible to mask GPEs now (and the sysfs interface for GPE control is fixed on top of that), problems related to the table loading mechanism are fixed and all code related to FADT version 2 (which has never been part of the ACPI specification) is dropped. On the new features front, there is a new watchdog driver based on the ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to replace the iTCO watchdog that doesn't work there, and some UART devices get new definitions of built-in properties (to be accessed via the generic device properties API). Also, included is a fix for an ACPI-related PCI resorces allocation issue and a few problems in the EC driver and in the button and battery drivers are fixed. In addition to that, the ACPI CPPC library is updated to make batching of requests sent over the PCC channel possible (which reduces the PCC usage overhead substantially in some cases) and to support functional fixed hardware (FFH) type of CPPC registers access (which will allow CPPC to be used on x86 too in the future). As usual, there are some assorted fixes and cleanups too. Specifics: - Update of the ACPICA code in the kernel to upstream revision 20160831 with the following major changes: * New mechanism for GPE masking. * Fixes for issues related to the LoadTable operator and table loading. * Fixes for issues related to so-called module-level code (MLC), that is AML that doesn't belong to any methods. * Change of the return value of the _OSI method to reflect the Windows behavior. * GAS (Generic Address Structure) support fix related to 32-bit FADT addresses. * Elimination of unnecessary FADT version 2 support. * ACPI tools fixes and cleanups. From Bob Moore, Lv Zheng, and Jung-uk Kim. - ACPI sysfs interface updates to fix GPE handling (on top of the new GPE masking mechanism in ACPICA) and issues related to table loading (Lv Zheng). - New watchdog driver based on the ACPI WDAT (ACPI Watchdog Action Table), needed on some platforms to replace the iTCO watchdog that doesn't work there and related updates of the intel_pmc_ipc, i2c/i801 and MFD/lcp_ich drivers (Mika Westerberg). - Driver core fix to prevent it from leaking secondary fwnode objects during device removal (Lukas Wunner). - New definitions of built-in properties for UART in ACPI-based x86 SoC drivers and a 8250_dw driver quirk for the APM X-Gene SoC (Heikki Krogerus). - New device ID for the Vulcan SPI controller and constification of local strucures in the AMD SoC (APD) ACPI driver (Kamlakant Patel, Julia Lawall). - Fix for a bug causing the allocation of PCI resorces to fail if ACPI-enumerated child platform devices are registered below the PCI devices in question (Mika Westerberg). - Change of the default polarity for PCI legacy IRQs to high on systems booting wth ACPI on platforms with a GIC interrupt controller model fixing the discrepancy between the specification and HW behavior (Lorenzo Pieralisi). - Fixes for the handling of system suspend/resume in the ACPI EC driver and update of that driver to make it cope with the cases when the EC device defined in the ECDT has to be used throughout the entire system life cycle (Lv Zheng). - Update of the ACPI CPPC library to allow it to batch requests sent over the PCC channel (to reduce overhead), to support the fixed functional hardware (FFH) CPPC registers access type, to notify the mailbox framework about TX completions when the interrupt flag is set for the PCC mailbox, and to support HW-Reduced Communication Subspace type 2 (Ashwin Chaugule, Prashanth Prakash, Srinivas Pandruvada, Hoan Tran). - ACPI button driver fix and documentation update related to the handling of laptop lids (Lv Zheng). - ACPI battery driver initialization fix (Carlos Garnacho). - ACPI GPIO enumeration documentation update (Mika Westerberg). - Assorted updates of the core ACPI bus type code (Lukas Wunner, Lv Zheng). - Assorted cleanups of the ACPI table parsing code and the x86-specific ACPI code (Al Stone). - Fixes for assorted ACPI-related issues found in linux-next (Wei Yongjun)" * tag 'acpi-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (98 commits) ACPI / documentation: Use recommended name in GPIO property names watchdog: wdat_wdt: Fix warning for using 0 as NULL watchdog: wdat_wdt: fix return value check in wdat_wdt_probe() platform/x86: intel_pmc_ipc: Do not create iTCO watchdog when WDAT table exists i2c: i801: Do not create iTCO watchdog when WDAT table exists mfd: lpc_ich: Do not create iTCO watchdog when WDAT table exists ACPI / bus: Adjust ACPI subsystem initialization for new table loading mode ACPICA: Parser: Fix a regression in LoadTable support ACPICA: Tables: Fix "UNLOAD" code path lock issues ACPI / watchdog: Add support for WDAT hardware watchdog ACPI / platform: Pay attention to parent device's resources PCI: Add pci_find_resource() ACPI / CPPC: Support PCC with interrupt flag ACPI / sysfs: Update sysfs signature handling code ACPI / sysfs: Fix an issue for LoadTable opcode ACPICA: Tables: Fix a regression in acpi_tb_find_table() ACPI / tables: Remove duplicated include from tables.c ACPI / APD: constify local structures x86: ACPI: make variable names clearer in acpi_parse_madt_lapic_entries() x86: ACPI: remove extraneous white space after semicolon ...
