The driver core clears the driver data to NULL after device_release
or on probe failure, since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound).
Thus, it is not needed to manually clear the device driver data to NULL.

This is MFD module providing access to registers and interrupts of DA906x
series PMIC. It is used by other functional modules, registered as MFD cells.
Driver uses regmap with paging to access extended register list. Register map
is divided into two pages, where the second page is used during initialisation.
This module provides support to following functional cells:
- Regulators
- RTC
- HWMON
- OnKey (power key misc input device)
- Vibration (force-feedback input device)
- Watchdog

While powering up DA9055, both power sequencer and gpio events are received.
These events remain uncleared after boot up, due to which further event handling
also fails. DA9055 has three event registers. The event register bits are set
to '1' on receiving an event. The events can be cleared on writing a '1' to
the set bit, which would then clear that bit to '0'. After applying this patch

Merge tag 'pm+acpi-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management and ACPI updates from Rafael Wysocki:
"This time the total number of ACPI commits is slightly greater than
the number of cpufreq commits, but Viresh Kumar (who works on cpufreq)
remains the most active patch submitter.
To me, the most significant change is the addition of offline/online
device operations to the driver core (with the Greg's blessing) and
the related modifications of the ACPI core hotplug code. Next are the
freezer updates from Colin Cross that should make the freezing of
tasks a bit less heavy weight.
We also have a couple of regression fixes, a number of fixes for
issues that have not been identified as regressions, two new drivers
and a bunch of cleanups all over.
Highlights:
- Hotplug changes to support graceful hot-removal failures.
It sometimes is necessary to fail device hot-removal operations
gracefully if they cannot be carried out completely. For example,
if memory from a memory module being hot-removed has been allocated
for the kernel's own use and cannot be moved elsewhere, it's
desirable to fail the hot-removal operation in a graceful way
rather than to crash the kernel, but currenty a success or a kernel
crash are the only possible outcomes of an attempted memory
hot-removal. Needless to say, that is not a very attractive
alternative and it had to be addressed.
However, in order to make it work for memory, I first had to make
it work for CPUs and for this purpose I needed to modify the ACPI
processor driver. It's been split into two parts, a resident one
handling the low-level initialization/cleanup and a modular one
playing the actual driver's role (but it binds to the CPU system
device objects rather than to the ACPI device objects representing
processors). That's been sort of like a live brain surgery on a
patient who's riding a bike.
So this is a little scary, but since we found and fixed a couple of
regressions it caused to happen during the early linux-next testing
(a month ago), nobody has complained.
As a bonus we remove some duplicated ACPI hotplug code, because the
ACPI-based CPU hotplug is now going to use the common ACPI hotplug
code.
- Lighter weight freezing of tasks.
These changes from Colin Cross and Mandeep Singh Baines are
targeted at making the freezing of tasks a bit less heavy weight
operation. They reduce the number of tasks woken up every time
during the freezing, by using the observation that the freezer
simply doesn't need to wake up some of them and wait for them all
to call refrigerator(). The time needed for the freezer to decide
to report a failure is reduced too.
Also reintroduced is the check causing a lockdep warining to
trigger when try_to_freeze() is called with locks held (which is
generally unsafe and shouldn't happen).
- cpufreq updates
First off, a commit from Srivatsa S Bhat fixes a resume regression
introduced during the 3.10 cycle causing some cpufreq sysfs
attributes to return wrong values to user space after resume. The
fix is kind of fresh, but also it's pretty obvious once Srivatsa
has identified the root cause.
Second, we have a new freqdomain_cpus sysfs attribute for the
acpi-cpufreq driver to provide information previously available via
related_cpus. From Lan Tianyu.
Finally, we fix a number of issues, mostly related to the
CPUFREQ_POSTCHANGE notifier and cpufreq Kconfig options and clean
up some code. The majority of changes from Viresh Kumar with bits
from Jacob Shin, Heiko Stübner, Xiaoguang Chen, Ezequiel Garcia,
Arnd Bergmann, and Tang Yuantian.
- ACPICA update
A usual bunch of updates from the ACPICA upstream.
During the 3.4 cycle we introduced support for ACPI 5 extended
sleep registers, but they are only supposed to be used if the
HW-reduced mode bit is set in the FADT flags and the code attempted
to use them without checking that bit. That caused suspend/resume
regressions to happen on some systems. Fix from Lv Zheng causes
those registers to be used only if the HW-reduced mode bit is set.
Apart from this some other ACPICA bugs are fixed and code cleanups
are made by Bob Moore, Tomasz Nowicki, Lv Zheng, Chao Guan, and
Zhang Rui.
- cpuidle updates
New driver for Xilinx Zynq processors is added by Michal Simek.
Multidriver support simplification, addition of some missing
kerneldoc comments and Kconfig-related fixes come from Daniel
Lezcano.
- ACPI power management updates
Changes to make suspend/resume work correctly in Xen guests from
Konrad Rzeszutek Wilk, sparse warning fix from Fengguang Wu and
cleanups and fixes of the ACPI device power state selection
routine.
- ACPI documentation updates
Some previously missing pieces of ACPI documentation are added by
Lv Zheng and Aaron Lu (hopefully, that will help people to
uderstand how the ACPI subsystem works) and one outdated doc is
updated by Hanjun Guo.
- Assorted ACPI updates
We finally nailed down the IA-64 issue that was the reason for
reverting commit 9f29ab11dd ("ACPI / scan: do not match drivers
against objects having scan handlers"), so we can fix it and move
the ACPI scan handler check added to the ACPI video driver back to
the core.
A mechanism for adding CMOS RTC address space handlers is
introduced by Lan Tianyu to allow some EC-related breakage to be
fixed on some systems.
A spec-compliant implementation of acpi_os_get_timer() is added by
Mika Westerberg.
The evaluation of _STA is added to do_acpi_find_child() to avoid
situations in which a pointer to a disabled device object is
returned instead of an enabled one with the same _ADR value. From
Jeff Wu.
Intel BayTrail PCH (Platform Controller Hub) support is added to
the ACPI driver for Intel Low-Power Subsystems (LPSS) and that
driver is modified to work around a couple of known BIOS issues.
Changes from Mika Westerberg and Heikki Krogerus.
The EC driver is fixed by Vasiliy Kulikov to use get_user() and
put_user() instead of dereferencing user space pointers blindly.
Code cleanups are made by Bjorn Helgaas, Nicholas Mazzuca and Toshi
Kani.
- Assorted power management updates
The "runtime idle" helper routine is changed to take the return
values of the callbacks executed by it into account and to call
rpm_suspend() if they return 0, which allows us to reduce the
overall code bloat a bit (by dropping some code that's not
necessary any more after that modification).
The runtime PM documentation is updated by Alan Stern (to reflect
the "runtime idle" behavior change).
New trace points for PM QoS are added by Sahara
(<keun-o.park@windriver.com>).
PM QoS documentation is updated by Lan Tianyu.
Code cleanups are made and minor issues are addressed by Bernie
Thompson, Bjorn Helgaas, Julius Werner, and Shuah Khan.
- devfreq updates
New driver for the Exynos5-bus device from Abhilash Kesavan.
Minor cleanups, fixes and MAINTAINERS update from MyungJoo Ham,
Abhilash Kesavan, Paul Bolle, Rajagopal Venkat, and Wei Yongjun.

These changes are all to SoC-specific code, a total of 33 branches on
17 platforms were pulled into this. Like last time, Renesas sh-mobile
is now the platform with the most changes, followed by OMAP and EXYNOS.
Two new platforms, TI Keystone and Rockchips RK3xxx are added in
this branch, both containing almost no platform specific code at all,
since they are using generic subsystem interfaces for clocks, pinctrl,
interrupts etc. The device drivers are getting merged through the
respective subsystem maintainer trees.
One more SoC (u300) is now multiplatform capable and several others
(shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
towards that goal with this series but need more work.
Also noteworthy is the work on PCI here, which is traditionally part of
the SoC specific code. With the changes done by Thomas Petazzoni, we can
now more easily have PCI host controller drivers as loadable modules and
keep them separate from the platform code in drivers/pci/host. This has
already led to the discovery that three platforms (exynos, spear and imx)
are actually using an identical PCIe host controller and will be able
to share a driver once support for spear and imx is added.
Conflicts:
* asm/glue-proc.h has one CPU type getting added that conflicts
with another addition in 3.10-rc7
* Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

drivers/pci/host. This has already led to the discovery that three
platforms (exynos, spear and imx) are actually using an identical PCIe
host controller and will be able to share a driver once support for
spear and imx is added."

The Patch adds TPS659038 PMIC support in the palmas mfd driver.
The TPS659038 has almost the same registers as of the earlier
supported variants of PALMAS family such as the TWL6035.
The critical differences between TPS659038 and TWL6035 being:
1) TPS659038 has nothing related to battery charging and back up battery stuff.
2) TPS659038 does not have does not have SMPS10(Boost) step up convertor.
3) TPS659038 does not have Battery detection and anything related to battery.
4) SD card detection, Battery presence detection, Vibrator, USB OTG are missing

The genirq IRQ wake method will default to failure if the irq_chip
does not provide a set_wake method. However, for TWL4030 sub-chip
IRQs, we want the wake enable to succeed even though we don't provide
a set_wake method. This allows sub-chip IRQs to still be flagged as
wakeup capable, and allow them to wakeup from suspend (or abort
suspend if they fire during suspend.)
To fix, use the IRQCHIP_SKIP_SET_WAKE flag in the irq_chip.

The TSC part allows to specify the input lines. The IIO part assumes
that it usues always the last few, that means if IIO has adc-channels
set to 2 it will use channel 6 and 7. However it might make sense to use
only 6.
This patch changes the device property (which was introduced recently
and was never in an official release) in a way that the user can specify
which of the AIN lines should be used. In Addition to this, the name is
now AINx where x is the channel number i.e. for AIN6 we would have 6.
Prior this, it always started counting at 0 which is confusing. In
addition to this, it also checks for correct step number during reading
and does not rely on proper FIFO depth.

The mfd driver creates platform data for the child devices and it is the
ti_tscadc_dev struct. This struct is copied for the two devices.
The copy of the structure makes a common lock in this structure a little
less usefull. Therefore the platform data is not a pointer to the
structure and the same structure is used.
While doing the change I noticed that the suspend/resume code assumes

The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core. It only is useful
for cpufreq drivers for their internal purposes.
Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.
Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0. If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.
Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.
To reduce overall code bloat, make the changes described above.

and also introduces the necessary cleanup code in the driver's remove

When booting with Device Tree enabled the MFD core uses each device's
compatible string to find and allocate its associated of_node pointer,
which in turn is passed to the driver via the platform_device struct.
Without it, the driver won't be able to interrogate the Device Tree or
locate suitable regulators and will most likely fail to probe.

When we're using Device Tree to enable GPIO drivers we're forced to be
OS agnostic, thus we are forbidden use names like pinctrl as they are
specific only to Linux, at least for the time being. However, when we
are registering devices using internal systems such as MFD or platform
registration, we can use such terminology. In this case we can and
should use the platform device ID mechanism to specify which device we
wish to utilise by detailing pinctrl-<device_name>.
This patch fixes a regression that when booting with Device Tree
enabled the ABx500 GPIO/Pinctrl devices are not probed.

The AB8500 debug code which was merged in parallell with the

the <mach/irqs.h> header which is now deleted, causing this
build regression:

fatal error: mach/irqs.h: No such file or directory

make[4]: *** [drivers/mfd/ab8500-debugfs.o] Error 1
The code most certainly never worked with device tree either
since that does not rely on this kind of hard-coded interrupt
numbers.
Fix the problem at the root by passing it as a named resource
from the ab8500-core driver. Use an untyped resource to
stop the MFD core from remapping this IRQ relative to the

Merge tag 'mfd-3.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-next
Pull MFD update from Samuel Ortiz:
"For 3.10 we have a few new MFD drivers for:
- The ChromeOS embedded controller which provides keyboard, battery
and power management services. This controller is accessible
through i2c or SPI.
- Silicon Laboratories 476x controller, providing access to their FM
chipset and their audio codec.
- Realtek's RTS5249, a memory stick, MMC and SD/SDIO PCI based
reader.
- Nokia's Tahvo power button and watchdog device. This device is
very similar to Retu and is thus supported by the same code base.
- STMicroelectronics STMPE1801, a keyboard and GPIO controller
supported by the stmpe driver.
- ST-Ericsson AB8540 and AB8505 power management and voltage
converter controllers through the existing ab8500 code.
Some other drivers got cleaned up or improved. In particular:
- The Linaro/STE guys got the ab8500 driver in sync with their
internal code through a series of optimizations, fixes and
improvements.
- The AS3711 and OMAP USB drivers now have DT support.
- The arizona clock and interrupt handling code got improved.
- The wm5102 register patch and boot mechanism also got improved."

Mostly many small changes spread as seen in diffstat in sound/*
directory by this update. A significant change in the subsystem level
is the introduction of snd_soc_component, which will help more generic
handling of SoC and off-SoC components.
Also, snd_BUG_ON() macro is enabled unconditionally now due to its
misuses, so people might hit kernel warnings (it's a good thing for
us).

One of the larger platforms remaining is Samsung Exynos, and there are
a bunch of supporting patches in this merge window for it. There was a
patch in this branch to a early version of multiplatform conversion,
but it ended up being reverted due to need of more bake time. The
revert commit is part of the branch since it would have required
rebasing multiple dependent branches and they were stable by then.

driver comes through the battery tree. It has an appropriate ack from
the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson
and Hongbo Zhang at Linaro authored the driver;

touch mfd parts, but these were acked by the appropriate MFD maintainer
(i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
the submission process.
Minor changes, but still worth mentioning:

This implements device tree support for the AB3100 regulators
driver. The initial settings are moved out of platform data
and into the driver for the device tree case, as it appears
that there is no way to supply this as AUXDATA for an I2C
device. The style and bindings are heavily inspired by
Lee Jones' style for AB8500.

For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

Palmas device have three different i2c addresses. The device creates
the two new dummy i2c clients for accessing the register by using
primary client adapter. This new dummy i2c client have their of_node
as NULL.
The dummy i2c client is used for registering interrupt and on this,
it creates irq domain handle. This created irq domain handle has
their of_node as NULL.
Now when any child of this device is registered through the DT as
follows:
palmas: tps65913@58 {
::::::::::::::::::
#interrupt-cells = <2>;
interrupt-controller;
palmas_rtc {
compatible = "ti,palmas-rtc";
interrupt-parent = <&palmas>;
interrupts = <8 0>;
};
::::::::::;;;
};
And child driver (palam-rtc in this case) get their irq number as
irq = platform_get_irq(pdev, 0);
The returned irq number is error in this case. The reason is that
the created irq_domain handle for the palmas interrupt does not have
valid node and so matching of node fails with palmas node.
Hence initialising the newly dummy created client->of_node with the
primary clients of_node so that irq_domain handle have proper of_node
for matching.

We are trying to decompose and decentralize the code in
the DB8500 PRCMU out into subdrivers. The code moved in
this patch concerns a group of functions used for
decoupling and recoupling the IRQs from the GIC. During
sleep and idle the Ux500 system will transfer all IRQ
handling to the PRCMU using these functions.
Basically we are left with the two alternatives of code
placement as:
- arch/arm/mach-ux500/pm.c - this because the code is
closely related to the GIC, and takes ownership of
some of the registers from the PRCMU related to this
PM functionality.
- drivers/mfd/db8500-prcmu-pm.c - because the code is
affecting stuff in the PRCMU register range. But then
this code needs to remap and handle GIC registers.
This patch implementation is taking the first approach.
Currently the cpuidle driver is the only piece of code
using this set of functions, but it will later also be
used by the suspend/resume code which is currently under
review.
The header file is moved to:
<linux/platform_data/arm-ux500-pm.h>
The function prototypes need to be placed in a globally
visible header since the CPUidle code is planned to move
out to drivers/cpuidle.

We cannot use a global variable stored in <mach/hardware.h> to
find the base address of the PRCMU. The real resource is already
there from the board, so use this to look up the base address
instead.
Currently the patch is kept minimal so as not to interfere with

This patch will make an early remapping of the PRCMU, to be
used when setting up the clocks, that will call down into parts
of the PRCMU driver before it is probed.
Going forward this will be removed like this:
- The mailbox subsystem need to be merged.
http://marc.info/?l=linux-kernel&m=136314559201983&w=2
- At this point the PRCMU clock code can be moved over to the
ux500 clock driver in drivers/clk/ux500/* and maintained
there in a decentralized manner.
- This early initcall and PRCMU base parameters become part of
the ux500_clk_init() call instead.

As I am working on SPARSE_IRQ a number of implicit resource
grabs in the kernel become evident. For example, some includes
like <linux/irqs.h> would implicitly include <mach/irqs.h>
and then from there <mach/db8500-regs.h>.
In many cases it is masking the fact that drivers do not
properly use resources to pass their dependencies, base
addresses etc. So write explicit #include statements with
TODO items to have this fixed the proper way to all drivers
doing this.

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.

Here is the big driver core merge for 3.9-rc1
There are two major series here, both of which touch lots of drivers all
over the kernel, and will cause you some merge conflicts:
- add a new function called devm_ioremap_resource() to properly be
able to check return values.
- remove CONFIG_EXPERIMENTAL
If you need me to provide a merged tree to handle these resolutions,
please let me know.
Other than those patches, there's not much here, some minor fixes and
updates.

The current probe aborts if any of the 3 base address registers are
disabled. On a TunnelCreek system I am working on, this resulted in the
SMBIOS and GPIO devices being removed when it couldn't read the base
address for the watchdog timer.
This patch accommodates partial population of the lpc_sch_cells array and
only aborts if all the base address registers are disabled. A max size
array is allocated and the individual device cells are added to it after
their base addresses are successfully determined. This simplifies the
code a bit by removing the need for the separate tunnelcreek cells array
and combining some of the add/remove logic.

Commit 8a6aaa3 (mfd: twl-core: Collect global variables behind one
private structure (global)) removed the variable "inuse" that is used
to determine if the device has been initialised and now use the
twl_priv structure instead. This is causing the kernel to panic on
OMAP3+ devices using the twl driver, because we try to access the
twl_priv->ready member before checking if twl_priv is initialised. Fix
this and move this test to the beginning of the twl_i2c_read/write
function because twl_get_last_module() also uses the twl_priv structure.

Realtek card reader supports both SD and MS card. According to the
settings of rtsx MFD driver, SD host will be probed before MS host.
If we boot/reboot Linux with SD card inserted, the resetting flow of SD
card will succeed, and the following resetting flow of MS is sure to fail.
Then MS upper-level driver will ask rtsx driver to turn power off. This
request leads to the result that the following SD commands fail and SD card
can't be accessed again.
In this commit, Realtek's SD and MS host driver will check whether the card
that upper driver requesting is the one existing in the slot. If not, Realtek's
host driver will refuse the operation to make sure the exlusive accessing
at the same time.

Runtime power management does not function during system suspend but the
Arizona devices need to use runtime power management to power up the device
in order to handle interrupts. Try to avoid interrupts firing during
resume by disabling the primary IRQ before interrupts are reenabled on
resume and only reenabling it again during main resume.
The goal is to avoid issues in the situation where an interrupt is asserted
during resume (eg, due to it being the wake source) and the interrupt
handling gets scheduled prior to the device being able to handle runtime
PM.

When trying to get rid of the cross-includes of <mach/id.h>
from different drivers, so we can localize ASIC/CPU detection
to the mach-ux500 folder, we run into the way the PRCMU
handles base addresses and firmware detection.
This patch updates the firmware version detection to pass
the required information as platform data instead of
relying on cpu_is_* macros.
Now the PRCMU base address, the secondary TCDM area, the
TCPM area and the IRQ are passed as resources instead of
being grabbed from <mach/*> files. Incidentally this also
removes part of the reliance on <mach/irqs.h>.
Further it updates the firmware version detection, since the
location of the firmware ID bytes in the designated memory
are is now passed from the platform data instead. There is
no reason not to include the nice split-off of a struct to
hold the firmware information and a separate function to
populate it.
The patch actually rids the need to use the external
db8500_prcmu_early_init call at all, but I'm keepin back
that removal as I don't want the patch to be too big.

In the AB8500 IRQ mask and unmask functions, we rely on testing for
IRQ_TYPE_EDGE_RISING and IRQ_TYPE_EDGE_FALLING interrupts to
physically mask and unmask the correct interrupt lines. In order
for us to do that, the trigger needs to be set in the associated
flags. However, unless a irq_set_type() function pointer is passed
when registering the IRQ chip, the IRQ subsystem will refuse to do
it. For that reason, we're providing one.

The patch:
"mfd: ab8500: prepare to handle AB8500 GPIO's IRQs correctly"
altered the AB8500 IRQ mask/unmask functions such that they
would handle masking on/off the falling edge IRQ if this was
requested by the consumer. However the bit mask for hwirqs
43 and 44 was shifting the bit mask incorrectly, resulting in
the wrong IRQ being mased/unmasked.
Further while the patch would mask/unmask the correct line,
when the interrupt actually came in, it would still be treated
as a valid hwirq. The offsetting applied when masking/unmasking
was not applied when handling the IRQ, i.e. the falling edge
lines were not routed back to the rising edge lines.
This fixes both cases. The end result has been tested with
the SIM detect IRQ, GPIO12, hwirq 46 and 62.

In an upcoming patch, the gpio-ab8500 driver will relinquish all
IRQ handling capability and pass it back into the AB8500 core
driver. This will aid in reducing massive code duplication within
the kernel. Also, most of the functionality is already in the
AB8500 core driver, as the GPIO IRQs are actually sandwiched
between lots of other IRQs which the core driver already handles.
All we're doing here is providing the core driver with knowledge
that each GPIO has two IRQs assigned to it; one for rising and
a separate one for falling.

Merge tag 'ux500-no-idh' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/cleanup
From Linus Walleij:
Removal of the <mach/id.h> include from ux500
- First an ACKed MFD patch deleting the only consumer
of these cpu_is* functions outside of mach-ux500
- Introduce a new local cpu_is_u8580() in this patch
set to avoid clashing with other patch sets.
- Finally de-globalize <mach/id.h>.

An issue has been reported where the PMIC either locks up or fails to
respond following a system Reset. This could result in a second write
in which the bus writes the current content of the write buffer to address
of the last I2C access.
The failure case is where this unwanted write transfers incorrect data to
a critical register.
This patch fixes this issue to by following any read or write with a dummy read
to a safe register address. A safe register address is one where the contents
will not affect the operation of the system.

If charging is started before USB enumeration of an Accessory
Charger Adapter has finished, the AB8500 will generate a
VBUS_ERROR. This in turn results in timeouts and delays the
enumeration with around 15 seconds. This patch delays the
charging and then ramps currents slowly to avoid VBUS errors.
The delay allows the enumeration to have finished before
charging is turned on.

This fixes a regression in the TC3589x driver introduced in
commit 15e27b1088
"mfd: Provide the tc3589x with its own IRQ domain"
If a system with a TC3589x expander is booted and a base
IRQ is passed from platform data, a legacy domain will
be used. However, since the Ux500 is now switched to use
SPARSE_IRQ, no descriptors get allocated on-the-fly,
and we get a crash.
Fix this by switching to using the simple irqdomain that
will handle this uniformly and also allocates descriptors
explicitly.
Also fix two small whitespace errors in the vicinity while
we're at it.

This fixes two issues with the DB8500 PRCMU irqdomain:
- You have to state the irq base 0 to get a linear domain
for the DT case from irq_domain_add_simple()
- The irqdomain was not used to translate the initial irq
request using irq_create_mapping() making the linear
case fail as it was lacking a proper descriptor.
I took this opportunity to fix two lines of whitespace
errors in related code as I was anyway messing around with
it.

Merge tag 'omap-for-v3.8/fixes-for-merge-window-v4-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
These patches fixes a build error caused by a merge
conflict with the fb code, few timer warnings, and longer
term regressions for tfp410 and omap h4 ethernet. Also
included is a GPIO mode fix for the legacy mux code.
* tag 'omap-for-v3.8/fixes-for-merge-window-v4-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: common: remove use of vram
ARM: OMAP: Move plat/omap-serial.h to include/linux/platform_data/serial-omap.h
ARM: dts: Add build target for omap4-panda-a4
ARM: dts: OMAP2420: Correct H4 board memory size
mfd: omap-usb-host: get rid of cpu_is_omap..() macros
ARM: OMAP: Remove debug-devices.c
ARM: OMAP2420: Fix ethernet support for OMAP2420 H4
OMAP2+: mux: Fixed gpio mux mode analysis
OMAP: board-files: fix i2c_bus for tfp410
ARM: OMAP2+: Fix sparse warnings in timer.c
ARM: AM335x: Fix warning in timer.c
ARM: OMAP2+: Fix realtime_counter_init warning in timer.c
We have several new drivers, most of the time coming with their sub devices
drivers:
- Austria Microsystem's AS3711
- Nano River's viperboard
- TI's TPS80031, AM335x TS/ADC,
- Realtek's MMC/memstick card reader
- Nokia's retu
We also got some notable cleanups and improvements:
- tps6586x got converted to IRQ domains.
- tps65910 and tps65090 moved to the regmap IRQ API.
- STMPE is now Device Tree aware.
- A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
APIs and a conversion to the recently added PWM framework.
- sta2x11 gained regmap support.
Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
wm5xxx and wm8xxx patchset.

Far amount of annoying but largely trivial conflicts. Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

Instead of using cpu_is_omap..() macros in the device driver we
rely on information provided in the platform data.
The only information we need is whether the USB Host module has
a single ULPI bypass control bit for all ports or individual bypass
control bits for each port. OMAP3 REV2.1 and earlier have the former.

series of ARMv7 platforms from them, where the hope is that we can
keep the platform code generic enough to have them all share one mach
directory. The new Broadcom platform is contributed by Christian Daudt.
Highbank has grown support for Calxeda's next generation of hardware,
ECX-2000.
clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
taken on maintainership of the platform.
Beyond this there has been a bunch of work from a number of people on
converting more platforms to IRQ domains, pinctrl conversion, cleanup
and general feature enablement across most of the active platforms.

Note, some MFD drivers got added through this tree, and they are also

Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This is
going to be a pain for the merge with different subsystem trees, I know,
but all of the patches included here have been ACKed by their various
subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
it's up to you. The merges should all be trivial, and Stephen has been
doing them all in linux-next for a few weeks now quite easily.
Other than the __dev* marking removals, there's nothing major here, some
firmware loading updates and other minor things in the driver core.

Currently the AB8500 battery management subsystem receives platform
specific information via two different means depending on how the
platform is booted. If DT is not enabled, a reference to a *_bm_data
data structure containing each platform specific attribute is passed
though platform_data. However, if DT is enabled, then platform_data
is empty and the reference is gained though a DT specific probe
function. There are two issues here 1) the same reference is
being collected each time and 2) the DT way doesn't allow any
provisions to select different platform specific attributes, which
kind of defeats the object.

Make sure that we don't race with the initial device boot by only doing
the initialisation after we've waited for the boot to complete.
The runtime PM code already waits for the boot to complete before it
syncs the register patches so in most systems if a race does occur we will
power down very soon afterwards and recover anyway.

The interrupt status registers of TPS65910/1 should be cleared
when the associated interrupt event occurs.
This work is done in the regmap irq thread - using 'ack_base' register.
The ACK registers should be fixed as status register, not mask registers.
This patch fixes the infinite interrupt event problem by clearing

The 'io_mutex' is not used anywhere.
The regmap API supports the mutex internally, so no additional mutex
is required.
And 'domain' private data is unnecessary because the irq domain is
already registered by using regmap_add_irq_chip().

Since the very first patch, stmpe core driver is using irq_invert_polarity as
part of platform data. But, nobody is actually using it in kernel till now.
Also, this is not something part of hardware specs, but is included to cater
some board mistakes or quirks.
So, better get rid of it. This is earlier discussed here:

A driver for the apb-soc registers is needed by the clock
infrastructure code to configure and control clocks on the sta2x11
chip.
Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:
* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.

mfd_remove_devices would iterate over all devices sharing a parent with
an mfd device regardless of whether they were allocated by the mfd core
or not. This especially caused problems when the device structure was
not contained within a platform_device, because to_platform_device is
used on each device pointer.
This patch defines a device_type for mfd devices and checks this is
present from mfd_remove_devices_fn before processing the device.

On a mx53qsb dt-kernel the da9052-core driver fails to probe as follows:
da9052 1-0048: DA9052 ADC IRQ failed ret=-22
The reason for the error was due to passing only the offset as the interrupt
number in request_threaded_irq() without da9052->irq_base.
The recommended approach though is to use regmap_get_virq() to acquire the
interrupt number and this allows to get rid of da9052->irq_base.
Fix it and allow the driver to probe successfully.
Also provide a few more error logs and change the irq string to "adc-irq", so
that it appears as a single word in 'cat /proc/interrupts'

Moving regulator node parsing to regulator driver in place
of parsing it on mfd driver.
The motivation for this change are:
- MFD core driver should not depends on regulator and able
to instantiate device without regulator.
- The API for matching regulators are in regulator core and
it is good that regulator driver only calls this API.
- Regulator specific support should be in regulator driver only
to ease any enhancement/modification for regulators.
- The regulator driver is now registered as mfd sub device and
all regulator registration is done from single probe call.

Originally IRQ incrementers were provided in some template resource
structures for keypad and touchscreen devices. These were passed as
IORESOURCE_IRQs to MFD core in the usual way. The true device IRQs
were instead added to the irq_base when mfd_add_devices was invoked.
This is clearly an abuse of the call, and does not scale when IRQ
Domains are brought into play. Before we can provide the STMPE with
its own IRQ Domain we must first fix this. This patche keeps most
of the driver's structure, keeping the template strategy. However,
instead of providing the IRQ as an increment to irq_base, we
dynamically populate the IORESOURCE_IRQ with the correct device IRQ.

This is a platform driver for Versatile Express' "system
register" block. It's a random collection of registers providing
the following functionality:
- low level platform functions like board ID access; in order to
use those, the driver must be initialized early, either statically
or based on the DT
- config bus bridge via "system control" interface; as the response
from the controller does not generate interrupt (yet), the status
register is periodically polled using a timer
- pseudo GPIO lines providing MMC card status and Flash WP#
signal control
- LED interface for a set of 8 LEDs on the motherboard, with
"heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers
Signed-off-by: Pawel Moll <pawel.moll@arm.com>
Versatile Express platform has an elaborated configuration system,
consisting of microcontrollers residing on the mother- and
daughterboards known as Motherboard/Daughterboard Configuration
Controller (MCC and DCC). The controllers are responsible for
the platform initialization (reset generation, flash programming,
FPGA bitfiles loading etc.) but also control clock generators,
voltage regulators, gather environmental data like temperature,
power consumption etc. Even the video output switch (FPGA) is
controlled that way.
Those devices are _not_ visible in the main address space and
the usual communication channel uses some kind of a bridge in
the peripheral block sending commands (requests) to the
controllers and receiving responses. It can take up to
500 microseconds for a transaction to be completed, therefore
it is important to provide a non-blocking interface to it.
This patch adds an abstraction of this infrastructure. Bridge
drivers can register themselves with the framework. Then,
a driver of a device can request an abstract "function" - the
request will be redirected to a bridge referred by thedd
"arm,vexpress,config-bridge" property of the device tree node.

- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
ab8500, wm8994, wm5110, max8907 and the tps65xxx family.

Merge tag 'mfd-3.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD changes from Samuel Ortiz:
"MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
- TI LP8788
- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x,
palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."
Fix up various annoying conflicts: the DT and IRQ domain support came in
twice and was already in 3.6. And then it was apparently rebased.
Guys, DON'T REBASE!

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot of
driver/platform shared definitions have gone, such as platform data
structures. They now need to move out to a common location instead,
and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move and
once it settles in, we should be good for quite a while. Sorry for the
overhead.

This is a large branch that contains a handful of different cleanups:
- Fixing up the I/O space remapping on PCI on ARM. This is a series
from Rob Herring that restructures how all pci devices allocate I/O
space, and it's part of the work to allow multiplatform kernels.
- A number of cleanup series for OMAP, moving and removing some
headers, sparse irq rework and in general preparation for
multiplatform.
- Final removal of all non-DT boards for Tegra, it is now
device-tree-only!
- Removal of a stale platform, nxp4008. It's an old mobile chipset
that is no longer in use, and was very likely never really used with
a mainline kernel. We have not been able to find anyone interested
in keeping it around in the kernel.
- Removal of the legacy dmaengine driver on tegra
+ A handful of other things that I haven't described above.

Merge tag 'regulator-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator updates from Mark Brown:
- Support for putting regulators into bypass mode where they simply
switch their input to the output (mainly used for low power
retention).
- A new API for setting voltages based on a voltage plus tolerance
rather than an explicit voltage range.
- Lots of cleanups and API updates from Axel Lin.
- New driver for MAX8907.

TI LP8788 PMU provides regulators, battery charger, ADC,
RTC, backlight driver and current sinks.
This MFD patch supports the I2C communication using the regmap,
the interrupt handling using the linear IRQ domain and
configurable platform data structures for each driver module.
(Driver Architecture)
< mfd devices >
LP8788 HW .......... mfd .......... regulator drivers
I2C power supply driver
IRQs iio adc driver
rtc driver
backlight driver
current sink drivers
o regulators : LDOs and BUCKs
o power supply : Battery charger
o iio adc : Battery voltage/temperature
o rtc : RTC and alarm
o backlight
o current sink : LED and vibrator
All MFD device modules are registered by LP8788 MFD core driver.
For sharing information such like the virtual IRQ number,
MFD core driver uses the resource structure.
Then each module can retrieve the specific IRQ number and detect it
in the IRQ thread.
Configurable platform data is handled in each driver module.

Before the AB8500 had its own IRQ domain, the IRQ handler would take
the fired local IRQ (hwirq) and add it to the irq_base to convert it
to an IRQ number which Linux would understand (virq). However, the
IRQ base is not always used anymore since we can make use of Linear
domains. It's better to use the AB8500 hwirq -> virq mapping helper
function to convert them instead. That's what we do here.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke
compile for non-omap as include plat/cpu.h was added. This header
was indirectly included earlier when SPARSE_IRQ was not set, but
does not exist on most platforms.
Fix the problem by removing the cpu_is_omap usage that should
not exist in drivers at all. We can do this by adding proper
clock aliases for the twl-core.c drivers, and drop separate
handling for cases when clock framework is not available as
the behaviour will stay the same.
Note that we need to add a platform device to avoid using the
i2c provided names that may be different on various omaps.

The MAX8907 is an I2C-based power-management IC containing voltage
regulators, a reset controller, a real-time clock, and a touch-screen
controller.
The original driver was written by:
* Gyungoh Yoo <jack.yoo@maxim-ic.com>
Various fixes and enhancements by:
* Jin Park <jinyoungp@nvidia.com>
* Tom Cherry <tcherry@nvidia.com>
* Prashant Gaikwad <pgaikwad@nvidia.com>
* Dan Willemsen <dwillemsen@nvidia.com>
* Laxman Dewangan <ldewangan@nvidia.com>
During upstreaming, I (swarren):
* Converted to regmap.
* Converted to regmap-irq.
* Allowed probing from device tree.
* Renamed from max8907c->max8907, since the driver covers at least the
C and B revisions.
* General cleanup.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

The ICH chips have their GPIO pins organized in 2 or 3 independent
groups of 32 GPIO pins. It can happen that the ACPI BIOS wants to make
use of pins in one group, preventing the OS to access these. This does
not prevent the OS from accessing the other group(s).
This is the case for example on my Asus Z8NA-D6 board. The ACPI BIOS
wants to control GPIO 18 (group 1), while I (the OS) need to control
GPIO 52 and 53 (group 2) for SMBus multiplexing.
So instead of checking for ACPI resource conflict on the whole I/O
range, check on a per-group basis, and consider it a success if at
least one of the groups is available for the OS to use.

From "Uwe Kleine-Knig" <u.kleine-koenig@pengutronix.de>:
this is the 2nd version of this series whose goal is to make struct
of_device_id.data const. Conceptually a driver must not modify the data
contained there so making it const is the right thing.
v1 of this series was sent with Message-id:
1342182734-321-1-git-send-email-y. Changes since then are:
- powerpc fixes
- several new consts that were found by Arnd that are possible after
patch 19.
Arnd suggested to take this series via arm-soc late for 3.6 in one go
because patch 19 depends on the former patches but is a precondition to
the latter and it fixes a few warnings. So getting it in via the
respective maintainer trees would need a much bigger coordination
effort. That means I prefer getting Acks over you taking the patch.
Vinod Koul already took
dmaengine: at_hdmac: add a few const qualifiers
that is in next-20120723 as 7fd63ccdad now. Vinod, I don't follow your
pull requests, but assuming you didn't let it already pull for 3.6 I
suggest you drop it from your queue and I just take your Ack.
This series was build tested for arm (all defconfigs) and powerpc (all
defconfigs and an allyesconfig) and grep didn't find more issues. As
before it introduces a warning in drivers/regulator/twl-regulator.c.
This driver does modify its .of_match_table when a device is bound which
doesn't fits the concept of independant devices. Arnd noticed another
new warning in drivers/scsi/qlogicpti.c that isn't that easy to resolve,
because the pointer to (now) const data is passed as first argument to
scsi_host_alloc. To fix that properly struct Scsi_Host.hostt needs to
get a const, too. Alternatively I could introduce a cast removing the
const, but I don't like that.

Signed-off-by: Olof Johansson <olof@lixom.net>
As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.
Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.
While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.
Note that for drivers/staging/tidspbridge we just define things
locally.

The removal of mach/io.h from most ARM platforms also set the range of
valid IO ports to be empty for most platforms when previously any 32
bit integer had been valid. This makes it impossible to add IO resources
as the added range is smaller than that of the root resource for IO ports.
Since we're not really using IO memory at all fix this by defining our
own root resource outside the normal tree and make that the parent of
all IO resources. This also ensures we won't conflict with read IO ports
if we ever run on a platform which happens to use them.

There are many reports (including 2 of my machines) that iTCO_wdt watchdog
driver fails to be initialized in 3.5 kernel with error message like:
[ 5.265175] ACPI Warning: 0x00001060-0x0000107f SystemIO conflicts with Region \_SB_.PCI0.LPCB.TCOI 1 (20120320/utaddress-251)
[ 5.265192] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver
[ 5.265206] lpc_ich: Resource conflict(s) found affecting iTCO_wdt
The root cause the iTCO_wdt driver in 3.4 probes the HW IO resource from
LPC's PCI config space, while in 3.5 kernel it relies on lpc_ich driver
for the probe, which adds a new acpi_check_resource_conflict() check, and
give up the probe if there is any conflict with ACPI.
Fix it by removing all the checks for iTCO_wdt to keep the same behavior as
3.4 kernel.

Actually the same check could be removed for the gpio-ich in lpc_ich.c,
but I'm not sure if it will cause problems.
