More ACPI and power management updates for 3.19-rc1
- Fix a regression in leds-gpio introduced by a recent commit that
inadvertently changed the name of one of the properties used by
the driver (Fabio Estevam).
- Fix a regression in the ACPI backlight driver introduced by a
recent fix that missed one special case that had to be taken
into account (Aaron Lu).
- Drop the level of some new kernel messages from the ACPI core
introduced by a recent commit to KERN_DEBUG which they should
have used from the start and drop some other unuseful KERN_ERR
messages printed by ACPI (Rafael J Wysocki).
- Revert an incorrect commit modifying the cpupower tool
(Prarit Bhargava).
- Fix two regressions introduced by recent commits in the OPP
library and clean up some existing minor issues in that code
(Viresh Kumar).
- Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout
the tree (or drop it where that can be done) in order to make
it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki,
Ulf Hansson, Ludovic Desroches). There will be one more
"CONFIG_PM_RUNTIME removal" batch after this one, because some
new uses of it have been introduced during the current merge
window, but that should be sufficient to finally get rid of it.
- Make the ACPI EC driver more robust against race conditions
related to GPE handler installation failures (Lv Zheng).
- Prevent the ACPI device PM core code from attempting to
disable GPEs that it has not enabled which confuses ACPICA
and makes it report errors unnecessarily (Rafael J Wysocki).
- Add a "force" command line switch to the intel_pstate driver
to make it possible to override the blacklisting of some
systems in that driver if needed (Ethan Zhao).
- Improve intel_pstate code documentation and add a MAINTAINERS
entry for it (Kristen Carlson Accardi).
- Make the ACPI fan driver create cooling device interfaces
witn names that reflect the IDs of the ACPI device objects
they are associated with, except for "generic" ACPI fans
(PNP ID "PNP0C0B"). That's necessary for user space thermal
management tools to be able to connect the fans with the
parts of the system they are supposed to be cooling properly.

Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes. Everything has been in linux-next for a while.

ARM: SoC cleanup on mach-at91 for 3.19
On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer. All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle. This is split out from the other cleanups purely based on the size of the branch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iD8DBQBUhyNX5t5GS2LDRf4RAnjxAKCER7eoLNadu1/93n/a9d1nUz4MoQCcCZUq BolxCOi0wr4YTcQtp7rHzWI= =ykAB -----END PGP SIGNATURE----- Merge tag 'at91-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann: "On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer.

power: reset: adjust priority of simple syscon reboot driver
Currently, all restart handler use the priority 128, including watchdogs. Probably most SoC have a watchdog, and some of them register it also as a restart handler. But if a SoC specifies a dedicated reboot capability using this syscon driver, this is usually the preferred reboot method. Hence, raise the priority of this driver to 192.

power: charger-manager: Fix accessing invalidated power supply after charger unbind
The charger manager obtained in probe references to power supplies for
all chargers with power_supply_get_by_name() for later usage. However
if such charger driver was removed then this reference would point to
old power supply (from driver which was removed).
This lead to accessing invalid memory which could be observed with:

The charger-manager should get reference to fuel gauge power supply on
each use of get_property callback. The thermal zone 'tzd' field of
power supply should not be used because of the same reason.
Additionally this change solves also the issue with nested
thermal_zone_get_temp() calls and related false lockdep positive for
deadlock for thermal zone's mutex [1]. When fuel gauge is used as source of
temperature then the charger manager forwards its get_temp calls to fuel
gauge thermal zone. So actually different mutexes are used (one for
charger manager thermal zone and second for fuel gauge thermal zone) but
for lockdep this is one class of mutex.
The recursion is removed by retrieving temperature through power
supply's get_property().
In case external thermal zone is used ('cm-thermal-zone' property is
present in DTS) the recursion does not exist. Charger manager simply
exports POWER_SUPPLY_PROP_TEMP_AMBIENT property (instead of
POWER_SUPPLY_PROP_TEMP) thus no thermal zone is created for this power
supply.

power: charger-manager: Avoid recursive thermal get_temp call
The charger manager supports POWER_SUPPLY_PROP_TEMP property and acts as a thermal zone if any of these conditions match: 1. Fuel gauge used by charger manager supports POWER_SUPPLY_PROP_TEMP. 2. 'cm-thermal-zone' property is present in DTS (then it will supersede the fuel gauge temperature property). However in case 1 (fuel gauge reports temperature and 'cm-thermal-zone' is not set) the charger manager forwards its get_temp calls to fuel gauge thermal zone. This leads to reporting by lockdep a false positive deadlock for thermal zone's mutex because of nested calls to thermal_zone_get_temp(). This is false positive because these are different mutexes: one for charger manager thermal zone and second for fuel gauge thermal zone.

power_supply: Add no_thermal property to prevent recursive get_temp calls
Add a 'no_thermal' property to the power supply class. If true then thermal zone won't be created for this power supply in power_supply_register(). Power supply drivers may want to set it if they support POWER_SUPPLY_PROP_TEMP and they are forwarding this get property call to other thermal zone. If they won't set it lockdep may report false positive deadlock for thermal zone's mutex because of nested calls to thermal_zone_get_temp(). First is the call to thermal_zone_get_temp() of the driver's thermal zone. Thermal core gets POWER_SUPPLY_PROP_TEMP property from this driver. The driver then calls other thermal zone thermal_zone_get_temp() and returns result. Example of such driver is charger manager.

Memory allocated for 'name' was leaking if required binding properties

The memory for 'name' was allocated early at probe with kasprintf(). It

in that error path.
Fix the error path for parsing device tree properties.

power: bq2415x_charger: Properly handle ENODEV from power_supply_get_by_phandle
The power_supply_get_by_phandle() on error returns ENODEV or NULL.
The driver later expects obtained pointer to power supply to be
valid or NULL. If it is not NULL then it dereferences it in
bq2415x_notifier_call() which would lead to dereferencing ENODEV-value
pointer.
Properly handle the power_supply_get_by_phandle() error case by
replacing error value with NULL. This indicates that usb charger
detection won't be used.
Fix also memory leak of 'name' if power_supply_get_by_phandle() fails
with NULL and probe should defer.

ACPI and power management updates for 3.18-rc1
- Rework the handling of wakeup IRQs by the IRQ core such that
all of them will be switched over to "wakeup" mode in
suspend_device_irqs() and in that mode the first interrupt
will abort system suspend in progress or wake up the system
if already in suspend-to-idle (or equivalent) without executing
any interrupt handlers. Among other things that eliminates the
wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
flag with interrupts which don't really need it and should not
use it (Thomas Gleixner and Rafael J Wysocki).
- Switch over ACPI to handling wakeup interrupts with the help
of the new mechanism introduced by the above IRQ core rework
(Rafael J Wysocki).
- Rework the core generic PM domains code to eliminate code that's
not used, add DT support and add a generic mechanism by which
devices can be added to PM domains automatically during
enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
- Add debugfs-based mechanics for debugging generic PM domains
(Maciej Matraszek).
- ACPICA update to upstream version 20140828. Included are updates
related to the SRAT and GTDT tables and the _PSx methods are in
the METHOD_NAME list now (Bob Moore and Hanjun Guo).
- Add _OSI("Darwin") support to the ACPI core (unfortunately, that
can't really be done in a straightforward way) to prevent
Thunderbolt from being turned off on Apple systems after boot
(or after resume from system suspend) and rework the ACPI Smart
Battery Subsystem (SBS) driver to work correctly with Apple
platforms (Matthew Garrett and Andreas Noever).
- ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
code, adding support for 133MHz I2C source clock on Intel Baytrail
to it and making it avoid using UART RTS override with Auto Flow
Control (Heikki Krogerus).
- ACPI backlight updates removing the video_set_use_native_backlight
quirk which is not necessary any more, making the code check the
list of output devices returned by the _DOD method to avoid
creating acpi_video interfaces that won't work and adding a quirk
for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
- New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
- Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
Sudip Mukherjee, Yijing Wang, and Zhang Rui).
- cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
Rasmus Villemoes).
- cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
change among other things), ppc-corenet, powernv (Viresh Kumar,
Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
- cpuidle support for DT-based idle states infrastructure, new
ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
Rasmus Villemoes).
- ARM big.LITTLE cpuidle driver updates: support for DT-based
initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
Kevin Hilman).
- Rework of the test_suspend kernel command line argument and
a new trace event for console resume (Srinivas Pandruvada,
Todd E Brandt).
- Second attempt to optimize swsusp_free() (hibernation core) to
make it avoid going through all PFNs which may be way too slow on
some systems (Joerg Roedel).
- devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
- rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).
- PM core fix related to clock management (Geert Uytterhoeven).
- PM core's sysfs code cleanup (Johannes Berg).

Pull ACPI and power management updates from Rafael Wysocki:
"Features-wise, to me the most important this time is a rework of
wakeup interrupts handling in the core that makes them work
consistently across all of the available sleep states, including
suspend-to-idle. Many thanks to Thomas Gleixner for his help with
this work.
Second is an update of the generic PM domains code that has been in
need of some care for quite a while. Unused code is being removed, DT
support is being added and domains are now going to be attached to
devices in bus type code in analogy with the ACPI PM domain. The
majority of work here was done by Ulf Hansson who also has been the
most active developer this time.
Apart from this we have a traditional ACPICA update, this time to
upstream version 20140828 and a few ACPI wakeup interrupts handling
patches on top of the general rework mentioned above. There also are
several cpufreq commits including renaming the cpufreq-cpu0 driver to
cpufreq-dt, as this is what implements generic DT-based cpufreq
support, and a new DT-based idle states infrastructure for cpuidle.
In addition to that, the ACPI LPSS driver is updated, ACPI support for
Apple machines is improved, a few bugs are fixed and a few cleanups
are made all over.
Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
maintained by Kevin Hilman that will be merged through the PM tree.
Numbers-wise, the generic PM domains update takes the lead this time
with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
place goes to the wakeup interrupts handling rework (13 commits).

power: reset: use restart_notifier mechanism for msm-poweroff
This change replaces use of arm_pm_restart with recently introduced reset mechanism in Linux kernel called restart_notifier.

power: reset: driver for the Versatile syscon reboot
This driver enabled us to drive the reboot of the Versatile family of ARM reference boards. Even though only the RealView boards are supported initially, these boards all have the same procedure for reboot: - Write a magic value into an unlocking register - Write another magic value into a reset control register The driver will be reusable for Versatile and possibly also the Integrator family of reference boards.

PM / AVS: rockchip-io: add driver handling Rockchip io domains
IO domain voltages on some Rockchip SoCs are variable but need to be kept in sync between the regulators and the SoC using a special register. A specific example using rk3288: - If the regulator hooked up to a pin like SDMMC0_VDD is 3.3V then bit 7 of GRF_IO_VSEL needs to be 0. If the regulator hooked up to that same pin is 1.8V then bit 7 of GRF_IO_VSEL needs to be 1. Said another way, this driver simply handles keeping bits in the SoC's general register file (GRF) in sync with the actual value of a voltage hooked up to the pins. Note that this driver specifically doesn't include: - any logic for deciding what voltage we should set regulators to - any logic for deciding whether regulators (or internal SoC blocks) should have power or not have power If there were some other software that had the smarts of making decisions about regulators, it would work in conjunction with this driver. When that other software adjusted a regulator's voltage then this driver would handle telling the SoC about it. A good example is vqmmc for SD. In that case the dw_mmc driver simply is told about a regulator. It changes the regulator between 3.3V and 1.8V at the right time. This driver notices the change and makes sure that the SoC is on the same page.
