Pull ACPI and power management updates from Rafael Wysocki:
"ACPICA is the leader this time (63 commits), followed by cpufreq (28
commits), devfreq (15 commits), system suspend/hibernation (12
commits), ACPI video and ACPI device enumeration (10 commits each).
We have no major new features this time, but there are a few
significant changes of how things work. The most visible one will
probably be that we are now going to create platform devices rather
than PNP devices by default for ACPI device objects with _HID. That
was long overdue and will be really necessary to be able to use the
same drivers for the same hardware blocks on ACPI and DT-based systems
going forward. We're not expecting fallout from this one (as usual),
but it's something to watch nevertheless.
The second change having a chance to be visible is that ACPI video
will now default to using native backlight rather than the ACPI
backlight interface which should generally help systems with broken
Win8 BIOSes. We're hoping that all problems with the native backlight
handling that we had previously have been addressed and we are in a
good enough shape to flip the default, but this change should be easy
enough to revert if need be.
In addition to that, the system suspend core has a new mechanism to
allow runtime-suspended devices to stay suspended throughout system
suspend/resume transitions if some extra conditions are met
(generally, they are related to coordination within device hierarchy).
However, enabling this feature requires cooperation from the bus type
layer and for now it has only been implemented for the ACPI PM domain
(used by ACPI-enumerated platform devices mostly today).
Also, the acpidump utility that was previously shipped as a separate
tool will now be provided by the upstream ACPICA along with the rest
of ACPICA code, which will allow it to be more up to date and better
supported, and we have one new cpuidle driver (ARM clps711x).
The rest is improvements related to certain specific use cases,
cleanups and fixes all over the place.
Specifics:
- ACPICA update to upstream version 20140424. That includes a number
of fixes and improvements related to things like GPE handling,
table loading, headers, memory mapping and unmapping, DSDT/SSDT
overriding, and the Unload() operator. The acpidump utility from
upstream ACPICA is included too. From Bob Moore, Lv Zheng, David
Box, David Binderman, and Colin Ian King.
- Fixes and cleanups related to ACPI video and backlight interfaces
from Hans de Goede. That includes blacklist entries for some new
machines and using native backlight by default.
- ACPI device enumeration changes to create platform devices rather
than PNP devices for ACPI device objects with _HID by default. PNP
devices will still be created for the ACPI device object with
device IDs corresponding to real PNP devices, so that change should
not break things left and right, and we're expecting to see more
and more ACPI-enumerated platform devices in the future. From
Zhang Rui and Rafael J Wysocki.
- Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it
to handle system suspend/resume on Asus T100 correctly. From
Heikki Krogerus and Rafael J Wysocki.
- PM core update introducing a mechanism to allow runtime-suspended
devices to stay suspended over system suspend/resume transitions if
certain additional conditions related to coordination within device
hierarchy are met. Related PM documentation update and ACPI PM
domain support for the new feature. From Rafael J Wysocki.
- Fixes and improvements related to the "freeze" sleep state. They
affect several places including cpuidle, PM core, ACPI core, and
the ACPI battery driver. From Rafael J Wysocki and Zhang Rui.
- Miscellaneous fixes and updates of the ACPI core from Aaron Lu,
Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki.
- Fixes and cleanups for the ACPI processor and ACPI PAD (Processor
Aggregator Device) drivers from Baoquan He, Manuel Schölling, Tony
Camuso, and Toshi Kani.
- System suspend/resume optimization in the ACPI battery driver from
Lan Tianyu.
- OPP (Operating Performance Points) subsystem updates from Chander
Kashyap, Mark Brown, and Nishanth Menon.
- cpufreq core fixes, updates and cleanups from Srivatsa S Bhat,

Switch from acpi_video_unregister(), to acpi_video_unregister_backlight(),
so that the hotkeys handler registered by acpi-video stays in place.
Since there are no mappings for the atkbd raw codes for the brightness
keys used by newer Acer models in /lib/udev/hwdb.d/60-keyboard.hwdb, and
since we map the wmi events with a code of KE_IGNORE, we rely on acpi-video
to do the hotkey handling for us.
For laptops such as the Acer Aspire 5750 which uses intel gfx this works
despite us calling acpi_video_unregister() because the following happens:
1) acpi-video module gets loaded (as it is a dependency of acer-wmi and i915)
2) acpi-video does NOT call acpi_video_register()
3) acer-wmi loads (assume it loads before i915), calls
acpi_video_dmi_promote_vendor(); which sets
ACPI_VIDEO_BACKLIGHT_DMI_VENDOR
4) calls acpi_video_unregister -> not registered, nop
5) i915 loads, calls acpi_video_register
6) acpi_video_register registers the acpi_notifier for the hotkeys,
does NOT register a backlight device because of
ACPI_VIDEO_BACKLIGHT_DMI_VENDOR
But on the Acer Aspire 5750G, which uses nvidia graphics the following happens:
1) acpi-video module gets loaded (as it is a dependency of acer-wmi)
2) acpi-video calls acpi_video_register()
3) acpi_video_register registers the acpi_notifier for the hotkeys,
and a backlight device
4) acer-wmi loads, calls acpi_video_dmi_promote_vendor()
5) calls acpi_video_unregister, this unregisters BOTH the acpi_notifier for
the hotkeys AND the backlight device
And we end up without any handler for the brightness hotkeys. This patch fixes
this by switching over to acpi_video_unregister_backlight() which keeps the
hotkey handler in place.

The only real change is passing in event_mask to the formerly nested functions.
Otherwise it's just moving around function and macro code.
This is the only place in the Linux kernel where nested functions are still in
use. Nested functions aren't part of the C standards, and complicate the
generated code. Although the Linux Kernel has never set out to be entirely C
standard compliant, it is increasingly compliant to the standard which is
supported by other compilers such as Clang. The LLVMLinux project is working on
being able to compile the Linux kernel with Clang. The use of nested functions
blocks this effort.

Keyboard backlight can be always off, use some automatic trigger

The behaviour of the driver changes whereby previously when passed 1 it
tried to turn on backlight immediately now it does nothing. This is
however a bug fix since (a) it makes little sense to turn on the
backlight when control is automatic and (b) this behaviour is
consistent with what the windows driver does.

Hi all,
my panasonic cf-51 does no longer react to the suspend and hibernate
keys. I cannot tell when this started since I no longer use the machine
on a daily basis, but I suspect it started when userspace switched from
using /proc/acpi/event to the input layer, wich was quite some time ago ;-)
Today I investigated the issue and found that the firmware simply does
not generate any event on "key down" for those keys, but only on "key up".
The attached patch works around the problem.
Best regards,
Stefan

Subject: [PATCH] panasonic-laptop: fix sleep keys on CF-51
At least on my CF-51, both sleep and hibernate keys do not
generate "key down" events, only "key up". Because of this,
the input layer does ignore both keys. The work around is
to generate a key down event before the key up. To avoid
double events on non-broken firmware, this is only done if
no key down is ever seen for those keys.

Pull sound updates from Takashi Iwai:
"There have been lots of changes in ALSA core, HD-audio and ASoC, also
most of PCI drivers touched by conversions of printks. All these
resulted in a high volume and wide ranged patch sets in this release.
Many changes are fairly trivial, but also lots of nice cleanups and
refactors. There are a few new drivers, most notably, the Intel
Haswell and Baytrail ASoC driver.
Core changes:
- A bit modernization; embed the device struct into snd_card struct,
so that it may be referred from the beginning. A new
snd_card_new() function is introduced for that, and all drivers
have been converted.
- Simplification in the device management code in ALSA core; now
managed by a simple priority list instead
- Converted many kernel messages to use the standard dev_err() & co;
this would be the pretty visible difference, especially for
HD-audio.
HD-audio:
- Conexant codecs use the auto-parser as default now; the old static
code still remains in case of regressions. Some old quirks have
been rewritten with the fixups for auto-parser.
- C-Media codecs also use the auto-parser as default now, too.
- A device struct is assigned to each HD-audio codec, and the
formerly hwdep attributes are accessible over the codec sysfs, too.
hwdep attributes still remain for compatibility.
- Split the PCI-specific stuff for HD-audio controller into a
separate module, ane make a helper module for the generic
controller driver. This is a preliminary change for supporting
Tegra HDMI controller in near future, which slipped from 3.15
merge.
- Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED
fix for HP laptops, more ASUS subwoofer quirks, yet more Dell
laptop headset quirks
- Make the HD-audio codec response a bit more robust
- A few improvements on Realtek ALC282 / 283 about the pop noises
- A couple of Intel HDMI fixes
ASoC:
- Lots of cleanups for enumerations; refactored lots of error prone
original codes to use more modern APIs
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle
- Provide both manually and transparently locked DAPM APIs rather
than a mix of the two fixing some concurrency issues
- Start converting CODEC drivers to use separate bus interface
drivers rather than having them all in one file helping avoid
dependency issues
- DPCM support for Intel Haswell and Bay Trail platforms, lots of
fixes
- Lots of work on improvements for simple-card, DaVinci and the
Renesas rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of
the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
- Fixes for the simple-card DAI format DT mess
- DT support for a couple more devices.
- Use of the tdm_slot mapping in a few drivers
Others:
- Support of reset_resume callback for improved S4 in USB-audio
driver; the device with boot quirks have been little tested, which
we need to watch out in this development cycle
- Add PM support for ICE1712 driver (finally!); it's still pretty
partial support, only for M-Audio devices"

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.
- On top of the above, new sysfs attribute for ACPI device objects
allowing user space to check device status by triggering the
execution of _STA for its ACPI object. From Srinivas Pandruvada.
- ACPI core hotplug changes reducing code duplication, integrating
the PCI root hotplug with the core and reworking container hotplug.
- ACPI core simplifications making it use ACPI_COMPANION() in the
code "glueing" ACPI device objects to "physical" devices.
- ACPICA update to upstream version 20131218. This adds support for
the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves
debug facilities. From Bob Moore, Lv Zheng and Betty Dall.
- Init code change to carry out the early ACPI initialization
earlier. That should allow us to use ACPI during the timekeeping
initialization and possibly to simplify the EFI initialization too.
From Chun-Yi Lee.
- Clenups of the inclusions of ACPI headers in many places all over
from Lv Zheng and Rashika Kheria (work in progress).
- New helper for ACPI _DSM execution and rework of the code in
drivers that uses _DSM to execute it via the new helper. From
Jiang Liu.
- New Win8 OSI blacklist entries from Takashi Iwai.
- Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun
Guo, Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava,
Rashika Kheria, Tang Chen, Zhang Rui.
- intel_pstate driver updates, including proper Baytrail support,
from Dirk Brandewie and intel_pstate documentation from Ramkumar
Ramachandra.

Majewski.
- powernow-k6 cpufreq driver fixes from Mikulas Patocka.
