[GIT PULL] Thermal SoC management updates for v4.0-rc2

Hello Rui,

Please pull from

  git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git fixes

to receive Thermal SoC Management updates for v4.0-rc2 with top-most

b71d399c7f2fe06b60b96155ec0b9ae167334e4a:

  thermal: exynos: Clean-up code to use oneline entry for exynos compatible table (2015-02-24 15:00:00 -0400)

on top of commit c517d838eb7d07bbe9507871fab3931deccff539:

  Linux 4.0-rc1 (2015-02-22 18:21:14 -0800)

Specifics:
- Fixes in RCAR thermal driver to remove race conditions and fix fail path
- Fixes in TI thermal driver: removal of unnecessary code and build fix if !CONFIG_PM_SLEEP
- Cleanups in exynos thermal driver
- Add stubs for include/linux/thermal.h. Now drivers using thermal calls but that also work
without CONFIG_THERMAL will be able to compile for systems that don't care about thermal.

BR,

Eduardo Valentin

[v3.20] ACPI backlight problem

When I press backlight keys then normally OSD is shown and
backlight follows immediately the keystrokes step by step.

Now in v3.20 it behaves different:
When I press backlight keys at first nothing happens. If I watch a
video it is being stopped.
After some seconds OSD is shown, backlight changes - in one step - to
the new level and video continues.

Thanks, Jörg

[v3.20]: Missing /sys/class/ACAD directory OR Cannot release Mutex

Starting with kernel 3.19.0-05184-g18320f2, I often find my notebook
running with 'powersave' policy even if it is on AC.

It turned out that /sys/class/ACAD directory is missing and in the
logs I see:

ACPI Error: Cannot release Mutex [MUT0], not acquired (20150204/exmutex-376)
ACPI Error: Method parse/execution failed [\_SB_.ACAD._PSR] (Node
ffff880216028d48), AE_AML_MUTEX_NOT_ACQUIRED (20150204/psparse-536)
ACPI Exception: AE_AML_MUTEX_NOT_ACQUIRED, Error reading AC Adapter
state (20150204/ac-131)

At the last 25 startups since 3.19.0-05184-g18320f2 it occured 13 times.

It does not occur with kernels older than 3.19.0-05184-g18320f2.

Thanks, Jörg

[GIT PULL] More power management and ACPI updates for 3.20-rc1

Hi Linus,

Please pull from

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm+acpi-3.20-rc1-3

to receive one more batch of power management and ACPI updates for
v3.20-rc1 or v4.0-rc1 (whichever that will be) with top-most commit
3466b547e37b988723dc93465b7cb06b4b1f731f

 Merge branches 'pnp', 'pm-cpuidle' and 'pm-cpufreq'

on top of commit 99fa0ad92c4fd8b529c89b3640b42323984be761

 Merge tag 'suspend-to-idle-3.20-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

These are mostly fixes on top of the previously merged recent PM and
ACPI material.

First, one commit that broke the ACPI LPSS (Low-Power Subsystem) driver
on a Dell box is reverted and there are two stable-candidate fixes for
that driver.  Another fix cleans up two recently added ACPI EC messages
that look odd and the printk level of a noisy debug message in the core
ACPI resources handling code is reduced.

In addition to that we have two stable-candidate fixes for the s3c
cpufreq driver, two cpuidle powernv driver updates related to Device
Trees and a PNP subsystem cleanup that will allow us to get rid of some

[PATCH] ACPI / resources: Change pr_info() to pr_debug() for debug information

From: Rafael J. Wysocki <rafael.j.wysocki <at> intel.com>

Annoying and noisy ACPI debug messages are printed with pr_info()
after the recent ACPI resources handling rework.  Replace the
pr_info() with pr_debug() to reduce to noise level.

[PATCH] Revert "ACPI / LPSS: Remove non-existing clock control from Intel Lynxpoint I2C"

Revert commit b893e80e3147 ("ACPI / LPSS: Remove non-existing clock control
from Intel Lynxpoint I2C") because it causes touchpad to not load on Dell
XPS13.

Regression is a clear indication that not only some early prototype version
of Lynxpoint I2C but also newer versions can be doing clock gating even
documentation does not state it.

Therefore it is best to revert since this clock gating haven't caused known
issues on those Lynxpoint version which don't do clock gating.

[BUG] b893e80e3147 breaks touchpad on Dell XPS13

Hi,

Commit b893e80e3147 ("ACPI / LPSS: Remove non-existing clock control
from Intel Lynxpoint I2C") is causing my touchpad to not load on my
Dell XPS13.  I do not see any errors in the Xorg log, just 20 or so
lines missing where it would normally be loading the synaptics driver.
Reverting this commit against Linus's tree (i.e., commit a9724125ad01)
makes it happy again.

Let me know if you need any further info.

Regards,

Chris

[PATCH] Revert "x86/xen: Treat SCI interrupt as normal GSI interrupt"

This reverts commit b568b8601f05a591a7ff09d8ee1cedb5b2e815fe.

The commit in question causes a nasty regression on HP/Compaq
nc6000 where we fail to register the ACPI interrupt, and thus
lose eg. thermal notifications leading a potentially overheated
machine.

[PATCH] ACPI / video: Add disable_native_backlight quirk for SAMSUNG 900X3C/900X3D/900X3E/900X4C/900X4D

Hi

The native intel backlight controls do not work correctly on SAMSUNG
900X3C/900X3D/900X3E/900X4C/900X4D laptops as I reported in
https://bugs.freedesktop.org/show_bug.cgi?id=87286 (and
https://bugs.debian.org/772440).

Aaron Lu told me there to speak up here/to Rafael.

Please find attached a patch to disable the native backlight on this
laptop model, like it was already done for some other older models.

I assume this would be the proper commit comments (or should it be
signed-off?):
Bug-Link: https://bugs.freedesktop.org/show_bug.cgi?id=87286.
Reported-and-tested-by: Jens Reyer <jens.reyer <at> gmail.com>

The patch applies to
https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git
branch linux-next, head at
389a8d43d64711b0e7282d227e05a6a71b43753d
Rafael J. Wysocki 2015-02-12 22:43:26

I verified the issues are still present in linux-next and get solved
with this patch.

Just tell me if there is anything else I can do to get this applied.
