If the control bus is unrelabile we may hit errors during regcache_sync(),
especially given that it tends to be one the most dense bursts of I/O in
many systems.

Pull MFS update from Samuel Ortiz:
"This is the MFD patch set for the 3.8 merge window.
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.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"This update contains a fairly wide range of changes all over in sound
subdirectory, mainly because of UAPI header moves by David and __dev*
annotation removals by Bill. Other highlights are:
- Introduced the support for wallclock timestamps in ALSA PCM core
- Add the poll loop implementation for HD-audio jack detection
- Yet more VGA-switcheroo fixes for HD-audio
- New VIA HD-audio codec support
- More fixes on resource management in USB audio and MIDI drivers
- More quirks for USB-audio ASUS Xonar U3, Reloop Play, Focusrite,
Roland VG-99, etc
- Add support for FastTrack C400 usb-audio
- Clean ups in many drivers regarding firmware loading
- Add PSC724 Ultiimate Edge support to ice1712
- A few hdspm driver updates
- New Stanton SCS.1d/1m FireWire driver
- Standardisation of the logging in ASoC codes
- DT and dmaengine support for ASoC Atmel
- Support for Wolfson ADSP cores
- New drivers for Freescale/iVeia P1022 and Maxim MAX98090
- Lots of other ASoC driver fixes and developments"
Fix up trivial conflicts. And go out on a limb and assume the dts file
'status' field of one of the conflicting things was supposed to be
"disabled", not "disable" like in pretty much all other cases.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg Kroah-Hartman:
"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.
All of these have (much to Stephen's annoyance), been in linux-next
for a while.

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.

In the absence of a physical reset line the chip is reset by writing the
first register, which is done after the register patch has been applied.
This patch synchronises the register cache after the reset to preserve
any register changes that had been applied.

In the interrupt handler for an underclocked event, whilst checking for
the source of the interrupt, AIF3 was checked twice and AIF1 was not
checked. This change correctly checks the AIF1 underclocked bit and
reports the correct error messages for all cases.

wm5102_devs array was used for ARRAY_SIZE whilst adding the wm5110
devices. This change corrects this to get the size from the wm5110_devs
array. As both arrays are the same size no issues should have been
caused by this bug.

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.

Rather than open coding the enable GPIO control in the MFD core use the
API to push the management on to the regulator driver. The immediate
advantage is slight for most systems but this will in future allow device
configurations where an external regulator is used for DCVDD.

Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds core support for these devices.
In order to handle systems which do not use the generic clock API a
simple wrapper for the 32kHz clock domain in the devices is provided.
Once the generic clock API is widely available this code will be moved
over to use that.
For simplicity some WM5102 specific code is included in the core driver,
the effort involved in splitting the device out isn't worth it.
