Hi Linus,
This goes early as I will be traveling for a good part of the next week.
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-4.9-rc1
with top-most commit 8c4b172123c08a7138ee01675c130c83f9c1117c
Merge branches 'acpi-button', 'acpi-battery' and 'acpi-doc'
on top of commit 08895a8b6b06ed2323cd97a36ee40a116b3db8ed
Linux 4.8-rc8
to receive ACPI updates for v4.9-rc1.
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).
Thanks!
