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

The bulk of the changes for this release are a few new drivers however
there are a couple of noticable core changes and the usual stream of
cleanups and fixes:
- Move disable of unused regulators later in init so it comes after
deferred probe has iterated making startup smoother.
- Fixes reference counting of the DT nodes for constraints from Charles
Keepax. This has little practical impact since all real users of
the regulator bindings use FDT which doesn't need the reference
counting.
- Lots of cleanups, especially to the Samsung drivers.
- Support for Linear Technologies LTC3589, Texas Instruments TPS658640
and X-Powers AXP20x.

SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.
This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.
The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.
After discussion at last year's KS (and some more on the mailing lists),
we are here adding a drivers/soc directory. The purpose of this is
to keep per-vendor shared code that's needed by different drivers but
that doesn't fit into the MFD (nor drivers/platform) model. We expect
to keep merging contents for this hierarchy through arm-soc so we can
keep an eye on what the vendors keep adding here and not making it a
free-for-all to shove in crazy stuff.

Currently, all the power supply devices are registered with wakeup source,
this results in that every power_supply_changed() invocation brings
the system out of suspend-to-freeze state.
This is overkill as some device drivers, e.g. ACPI battery driver,
have the ability to check the device status and wake up the system
from sleeping only when necessary.
Thus introduce a new API which allows device to be registered
w/o wakeup source.

The keystone SoC can be rebooted in several ways. By external reset
pin, by soft and by watchdogs. To allow keystone SoC reset if
watchdog is triggered we have to enable it in reset mux configuration
register regarding of watchdog configuration. Also we need to set
soft/hard reset we are going to use.
So add keystone reset driver to handle all this stuff.

Here is version 4 of platform support for AXM5516 SoC.
The clk driver is now applied to clk-next. The rest should be ready for
arm-soc. Haven't got any response from the power/reset maintainers... I hope
this driver can be taken via arm-soc as well.
The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15
cores (in a 4x4 cluster configuration). The cores within each cluster share an

Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).
Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:
* a rework (and move to drivers/bus directory, as suggested
by Samuel and Arnd) of the config bus core, which is much
simpler now and uses device model infrastructure (class)
to keep track of the bridges; non-DT case (soon to be
retired anyway) is simply covered by a special device
registration function
* the new config-bus driver also takes over device population,
so there is no need for special matching table for
of_platform_populate nor "simple-bus" hack in the arm64
model dtsi file (relevant bindings documentation has
been updated); this allows all the vexpress devices
fit into normal device model, making it possible
to remove plenty of early inits and other hacks in
the near future
* adaptation of the syscfg bridge implementation in the
sysreg driver, again making it much simpler; there is
a special case of the "energy" function spanning two
registers, where they should be both defined in the tree
now, but backward compatibility is maintained in the code
* modification of the relevant drivers:
* hwmon - just a straight-forward API change
* power/reset driver - API change
* regulator - API change plus error handling
simplification
* osc clock driver - this one required larger rework
in order to turn in into a standard platform driver

The restart/power off implementation in the vexpress driver
used to obtain the config function when necessary. This was
wrong in two respects:
1. It required memory allocation with disabled interrupts
(it worked, but lockdep - when enabled - reported warnings).
2. Used jiffies-based timeout, while jiffies are not running
at this stage of system shutdown (therefore a config
transaction error - if happened - would have never be reported).
Fixed by pre-allocating the config function per device
and using mdelay for timeout.

Nearly all of the registers in tps65090 combine control bits and
status bits. Turn off caching of all registers except the select few
that can be cached.
In order to avoid adding more duplicate #defines, we also move some
register offset definitions to the mfd driver (and resolve
inconsistent names).

Charger-manager driver used to check battery temperature through the
callback function passed by platform data. Unfortunatley, without that
pre-defined callback function, charger-manager can't get battery's
temperature at all. Also passing callback function through platform data
ruins DT support for charger-manager.
This patch mondifies charger-manager driver to get temperature of battery
without pre-defined callback function. Now, charger-manager can use either
of battery thermometer in fuel-gauge and ouside of battery. It uses
thermal framework interface for outer thermometer if thermal fw is
enabled. Otherwise, it tries to use fuel-gauge's through the power supply
interface.

This patch adds a notifier chain to the power_supply, this helps drivers
in other subsystem to listen to changes in power supply subsystem.
This would help to take some actions in those drivers on changing the
power supply properties. One such scenario is to increase/decrease system
performance based on the battery capacity/voltage. Another scenario is to
adjust the h/w peak current detection voltage/current thresholds based on
battery voltage/capacity. The notifier helps drivers to listen to changes
in power_suppy susbystem without polling the power_supply properties

This patch, originally authored by Arve Hjonnevag and Todd Poynor,
prevents the system from entering suspend mode until the power supply
plug, unplug, or any other change of state event is fully processed. This
guarantees that the screen lights up and displays the battery charging
state. The implementation uses the power supply wakeup_source object.

Add driver support for the Texas Instruments BQ24190 battery charger.
Some of the information provided by the device is about the charger and
other information is about the battery so create two power_supply objects
(one for each) and provide the appropriate information for each one.
The device has many fields that go beyond what is reasonable to report or
modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver
exports the register fields via sysfs. They are prefixed by 'f_' (for
'field') to make it easier to distinguish between a register field and a
"normal" sysfs file exported by the power_supply infrastructure.

Nearly all the other goldfish peripherals (mtd, keyboard, etc) have a

skipped. Even with consistency as a justification, there was initial
resistance[1] from some people to adding it however, as they wanted the
extra compile coverage.
Now, with CONFIG_COMPILE_TEST, we have the middle ground that will give
people the coverage who want it, and let those who don't want it to skip

This patch prevents NULL pointer error cauesed by unregistering
unregistered exton notifier block. At the probing time of charger manager,
it tries to remove extcon notifier block when it fails to initialize them.
It has to be applied for only registered one. Otherwise, it'd make kernel
panic. To make it work right, it checks extcon_specific_cable_nb's
extcon_dev node. If extcon cable notifier block was registered
successfully, it has proper extcon_dev pointer if not so it has NULL
pointer.

vpboundsintr_en is available inside the IP block as an re-sycned
version and one which is not. Due to this, there is an 1 sysclk
cycle window where the SR_SInterruptz signal could be asserted low.
IF, intr_en is cleared on the exact same cycle as the irqclr, an
additional pulse is generated which indicates for VP that
an additional adjustment of voltage is required.
This results in VP doing two voltage adjustments for the SRERR
(based on configuration, upto 4 steps), instead of the needed
1 step.
Due to the unexpected pulse from AVS which breaks the AVS-VP
communication protocol, VP also ends up in a stuck condition by
entering a state where VP module remains non-responsive
to any futher AVS adjustment events. This creates the symptom
called "TRANXDONE Timeout" scenario.
By disabling errgen prior to disable of intr_en, this situation
can be avoided.

This patch fixes build failure(randconfig) of next-20130501. When config

The pm2301-charger driver implements runtime pm and at the same time uses
the legacy pm callbacks for suspend and resume. This does not work since
the I2C core wont look at the legacy pm callbacks if a driver has the 'pm'
field set. This patch fixes it by moving over to dev_pm_ops for
suspend/resume as well.
