duplicate bug fixes:
- Support for using the helpers with threaded interrupt
handlers as used on sleeping GPIO-irqchips
- Do not set up hardware triggers for edges or levels if
the default IRQ type is IRQ_TYPE_NONE - some drivers
would exploit the fact that you could get default
initialization of the IRQ type from the core at probe()
but if no default type is set up from the helper, we
should not call the driver to configure anything. Wait
until a consumer requests the interrupt instead.
- Make the irqchip helpers put the GPIO irqs into their
own lock class. The GPIO irqchips can often emit
(harmless, but annoying) lockdep warnings about recursions
when they are in fact just cascaded IRQs. By putting
them into their own lock class we help the lockdep core
to keep track of things.
- Switch the tc3589x GPIO expanders to use the irqchip
helpers
- Switch the OMAP GPIO driver to use the irqchip helpers
- Add some documentation for the irqchip helpers
- select IRQ_DOMAIN when using the helpers since some
platforms may not be using this by default and it's a
strict dependency.
- Continued GPIO descriptor refactoring:
- Remove the one instance of gpio_to_desc() from the
device tree code, making the OF GPIO code use GPIO
descriptors only.
- Introduce gpiod_get_optional() and
gpiod_get_optional_index() akin to the similar

We used to look for "foo-gpios" or just "gpios" in device
tree nodes, but it turns out that some drivers with a
single GPIO line will just state "foo-gpio" (singularis).
Sigh. Support this with a fallback looking for it, as
this simplifies driver code and handles it in core code.
- Switch the ACPI GPIO core to fetch GPIOs with the
*_cansleep function variants as the GPIO operation
region handler can sleep, and shall be able to handle

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v3.16 series.
There is a lot of action in the GPIO subsystem doing refactorings and
cleanups, almost as many deletions as insertions and minor feature
growth and no new drivers this time. Which is actually pretty nice.
Some GPIO-related stuff will come in through the pin control tree as
well.

This reverts commit c42deffd5b.
commit <mmc: rtsx: add support for pre_req and post_req> did use
mutex_unlock() in tasklet, but mutex_unlock() can't be used in
tasklet(atomic context). The driver needs to use mutex to avoid
concurrency, so we can't use tasklet here, the patch need to be
removed.
The spinlock host->lock and pcr->lock may deadlock, one way to solve
the deadlock is remove host->lock in sd_isr_done_transfer(), but if
using workqueue the we can avoid using the spinlock and also avoid

Add support for MAX77836 chipset and its additional two LDO regulators.
These LDO regulators are controlled by the PMIC block with additional
regmap (different I2C slave address).
The MAX77836 charger and safeout regulators are almost identical to
MAX14577. The registers layout is the same, except values for charger's
current. The patch adds simple mapping between device type and supported
current by the charger regulator.

Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
component so the extcon, charger and regulators are almost the same. The
MAX77836 however has also PMIC and Fuel Gauge.
The MAX77836 uses three I2C slave addresses and has additional interrupts
(related to PMIC and Fuel Gauge). It has also Interrupt Source register,
just like MAX77686 and MAX77693.
The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
PMIC block. The PMIC block has different I2C slave address and uses own
regmap so another regmap_irq_chip is needed.
Since we have two regmap_irq_chip, use shared interrupts on MAX77836.
This patch adds additional defines and functions to the max14577 MFD core
driver so the driver will handle both chipsets. Also this patch replaces
"0x1 << N" with BIT(N) in defines for register masks.

Add support for external control over GPIO for LDO10, LDO11 and LDO12
S2MPS14 regulators. External control can be turned on by writing 0x0 to
control register which in case of other regulators is used for disabling
them. These LDO10-LDO12 regulators can be disabled only by I2C GPIO or
PWREN pin so the patch actually allows proper way of disabling them.
Additionally the GPIO control has two benefits:
- It is faster than toggling it over I2C bus.
- It allows disabling the regulator during suspend to RAM; The AP will
enable it during resume.

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

There have been lots of changes in ALSA core, HD-audio and ASoC, also
most of PCI drivers touched by conversions of printks. All these
resulted in a high volume and wide ranged patch sets in this release.
Many changes are fairly trivial, but also lots of nice cleanups and
refactors. There are a few new drivers, most notably, the Intel
Haswell and Baytrail ASoC driver.
Core changes:
- A bit modernization; embed the device struct into snd_card struct,
so that it may be referred from the beginning. A new snd_card_new()
function is introduced for that, and all drivers have been
converted.
- Simplification in the device management code in ALSA core;
now managed by a simple priority list instead
- Converted many kernel messages to use the standard dev_err() & co;
this would be the pretty visible difference, especially for
HD-audio.
HD-audio:
- Conexant codecs use the auto-parser as default now;
the old static code still remains in case of regressions.
Some old quirks have been rewritten with the fixups for auto-parser.
- C-Media codecs also use the auto-parser as default now, too.
- A device struct is assigned to each HD-audio codec, and the formerly
hwdep attributes are accessible over the codec sysfs, too.
hwdep attributes still remain for compatibility.
- Split the PCI-specific stuff for HD-audio controller into a separate
module, ane make a helper module for the generic controller driver.
This is a preliminary change for supporting Tegra HDMI controller in
near future, which slipped from 3.15 merge.
- Device-specific fixes: mute LED support for Lenovo Ideapad,
mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more
Dell laptop headset quirks
- Make the HD-audio codec response a bit more robust
- A few improvements on Realtek ALC282 / 283 about the pop noises
- A couple of Intel HDMI fixes
ASoC:
- Lots of cleanups for enumerations; refactored lots of error prone
original codes to use more modern APIs
- Elimination of the ASoC level wrappers for I2C and SPI moving us
closer to converting to regmap completely and avoiding some
randconfig hassle
- Provide both manually and transparently locked DAPM APIs rather than
a mix of the two fixing some concurrency issues
- Start converting CODEC drivers to use separate bus interface drivers
rather than having them all in one file helping avoid dependency
issues
- DPCM support for Intel Haswell and Bay Trail platforms, lots of
fixes
- Lots of work on improvements for simple-card, DaVinci and the Renesas
rcar drivers.
- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8
- Fixes for the simple-card DAI format DT mess
- DT support for a couple more devices.
- Use of the tdm_slot mapping in a few drivers
Others:
- Support of reset_resume callback for improved S4 in USB-audio driver;
the device with boot quirks have been little tested, which we need
to watch out in this development cycle
- Add PM support for ICE1712 driver (finally!);
it's still pretty partial support, only for M-Audio devices

Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different
register layouts for the iTCO than the current v1 and v2 iTCO.
Differences from previous iTCO versions include:
- The ACPI space is enabled in the "ACPI base address" register instead
of the "ACPI control register"
- The "no reboot" functionality is set in the "Power Management
Configuration" register instead of the "General Control and Status"
(GCS) register or PCI configuration space.
- The "ACPI Control Register" is not present on v3. The "Power
Management Configuration Base Address" register resides at the same
address is Avoton/Bay Trail.
To differentiate these newer chipsets create a new v3 iTCO version and
update the MFD driver to support them.

The pm8xxx-irq.c code is practically mandatory given that the
pm8921-core driver will WARN about it missing and the Kconfig
marks it as default y when a PM8xxx chips is enabled. The only
reason the file was split out was because we planned to support
other pm8xxx chips with different pm8xxx-core.c files. Now that
we have DT on ARM this isn't necessary because we should be able
to support all the ssbi based PM8xxx chips in one driver and one
file with no data bloat. Let's move this code into the only
driver that uses it right now (pm8921) so that it's always compiled when
needed. In the future we can rename pm8921-core.c to something
more generic.

Add the correct silicon variant code ID (0x5) to the driver. This
new code is the 'production' variant code ID for DA9063.
This patch will remove the older variant code ID which matches the
pre-production silicon ID (0x3) for the DA9063 chip.
There is also some small amount of correction done in this patch:
it splits the revision code and correctly names it according to
the hardware specification and moves the dev_info() call before
the variant ID test.

The DBx500 and ABx500 should be getting their IRQs from the
device tree and nowhere else. Get rid of all the static assignments
everywhere, delete it from the driver, platform data and the
board files in one swift strike.
Lots of cross-dependencies in the MFD drivers for PRCMU and
AB8500 makes it necessary to strike everywhere at once to
eradicate IRQs passed as resources and platform data to the left
and right around the platform.

Add support for GPIO control (enable/disable) over Buck9. The Buck9
Converter is used as a supply for eMMC Host Controller.
BUCK9EN GPIO of S5M8767 chip may be used by application processor to
enable or disable the Buck9. This has two benefits:
- It is faster than toggling it over I2C bus.
- It allows disabling the regulator during suspend to RAM; The AP will
enable it during resume; Without the patch the regulator supplying
eMMC must be defined as fixed-regulator.

It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features;
now it's built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
and Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers;
now "make localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
Dell AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and managed
resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more modern
and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter
- Improvements to the constraints handling code from Lars-Peter
- A very helpful conversion of the TWL4030 driver to regmap from Peter
- A new driver for the Freescale ESAI controller from Nicolin Chen
- Conversion of some of the drivers to use params_width()
- Extensions to DPCM for use with compressed audio from Liam

Pull sound updates from Takashi Iwai:
"It was holiday season, so no wonder that there are little changes in
framework level, although diffstat shows quite many changes spreaded
over sound/* directories. Most of changes are cleanups, code
refactoring and fixes.
Some highlights:
- Removal of OSS sleep_on usages by Arnd
- Simplified memalloc helper codes, drop obsoleted features; now it's
built into PCM driver instead of an individual module
- Warn if PCM buffer preallocation fails, which will show page
allocation issues more clearly
- Compress offload API updates for sample rates by Vinod
- PCM glitch workaround on ctxfi emu20k1 by Sarah
- Drop cs46xx DSP blobs, using firmware loader now
- USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and
Focusrite Saffire 6
HD-audio specifics:
- Standardize Kconfigs of HD-audio codec drivers; now "make
localmodconfig" recognizes configs properly (finally!)
- Parallel PM implementation by Mengdong
- BayleyBay/ValleyView2 board fixups
- Broadwell audio support
- Runtime PM improvement (PantherPoint, etc)
- Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell
AiO click noise fixes, Dell headset mic fixes, etc
- Automatic bind with HDMI codec parser without generic parser
- More AD codec fixes (since 3.12 regression) including the automatic
stereo mix support
- Common Thinkpad ACPI helper for Realtek and Conexant codecs
ASoC specifics:
- Update to the generic DMA code to support deferred probe and
managed resources
- New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
and Analog Devices AXI I2S and S/PDIF controller IPs
- Device tree support for the simple card, max98090 and cs42l52
- Conversion of the Samsung drivers to native dmaengine, making them
multiplatform compatible and hopefully helping keep them more
modern and up to date.
- More regmap conversions, including a very welcome one for twl6040
from Peter Ujfalusi
- A big overhaul of the DaVinci drivers also from Peter Ujfalusi
- Lots of DMA updates from Lars-Peter

The ADC driver always programs all possible ADC values and discards
them except for the value IIO asked for. On the am335x-evm the driver
programs four values and it takes 500us to gather them. Reducing the number
of conversations down to the (required) one also reduces the busy loop down
to 125us.
This leads to another error, namely the FIFOCOUNT register is sometimes
(like one out of 10 attempts) not updated in time leading to EBUSY.
The next read has the FIFOCOUNT register updated.
Checking for the ADCSTAT register for being idle isn't a good choice either.
The problem is that if TSC is used at the same time, the HW completes the
conversation for ADC *and* before the driver noticed it, the HW begins to
perform a TSC conversation and so the driver never seen the HW idle. The
next time we would have two values in the FIFO but since the driver reads
everything we always see the current one.
So instead of polling for the IDLE bit in ADCStatus register, we should
check the FIFOCOUNT register. It should be one instead of zero because we
request one value.
This change in turn leads to another error. Sometimes if TSC & ADC are
used together the TSC starts generating interrupts even if nobody
actually touched the touchscreen. The interrupts seem valid because TSC's
FIFO is filled with values for each channel of the TSC. This condition stops
after a few ADC reads but will occur again. Not good.
On top of this (even without the changes I just mentioned) there is a ADC
& TSC lockup condition which was reported to me by Jeff Lance including the
following test case:
A busy loop of "cat /sys/bus/iio/devices/iio\:device0/in_voltage4_raw"
and a mug on touch screen. With this setup, the hardware will lockup after
something between 20 minutes and it could take up to a couple of hours.
During that lockup, the ADCSTAT register says 0x30 (or 0x70) which means
STEP_ID = IDLE and FSM_BUSY = yes. That means the hardware says that it is
idle and busy at the same time which is an invalid condition.
For all this reasons I decided to rework this TSC/ADC part and add a
handshake / synchronization here:
First the ADC signals that it needs the HW and writes a 0 mask into the
SE register. The HW (if active) will complete the current conversation
and become idle. The TSC driver will gather the values from the FIFO
(woken up by an interrupt) and won't "enable" another conversation.
Instead it will wake up the ADC driver which is already waiting. The ADC
driver will start "its" conversation and once it is done, it will
enable the TSC steps so the TSC will work again.
After this rework I haven't observed the lockup so far. Plus the busy
loop has been reduced from 500us to 125us.
The continues-read mode remains unchanged.

The purpose of reg_se_cache has been defeated. It should avoid the
read-back of the register to avoid the latency and the fact that the
bits are reset to 0 after the individual conversation took place.
The reason why this is required like this to work, is that read-back of
the register removes the bits of the ADC so they do not start another
conversation after the register is re-written from the TSC side for the
update.
To avoid the not required read-back I introduce a "set once" variant which
does not update the cache mask. After the conversation completes, the
bit is removed from the SE register anyway and we don't plan a new
conversation "any time soon". The current set function is renamed to
set_cache to distinguish the two operations.
This is a small preparation for a larger sync-rework.

On S5M8767A registers were not properly updated and read due to usage of

e.g. in infinite loop during waiting for UDR field change.
On this chip family the RTC has different I2C address than PMIC so

scattered over the whole sound subtree (which is a common pattern).
Below are highlights:

* Fix blocking in drain ioctl of compress_offload
- HD-audio:
* Improved AMD HDMI supports
* Intel HDMI detection improvements
* thinkpad_acpi mute-key integration
* New PCI ID, New ALC255,285,293 codecs, CX20952
- USB-audio:
* New buffer size management
* Clean up endpoint handling codes
- ASoC:
* Further work on the dmaengine helpers, including support for
configuring the parameters for DMA by reading the capabilities of
the DMA controller which removes some guesswork and magic numbers
from drivers.
* A refresh of the documentation.
* Conversions of many drivers to direct regmap API usage in order to
allow the ASoC level register I/O code to be removed, this will
hopefully be completed by v3.14.
* Support for using async register I/O in DAPM, reducing the time
taken to implement power transitions on systems that support it.

Lots of driver updates here plus some nice new core features, the main
one being the first:
- Enable support for providing a dummy regulator when we know that one
must exist for the device to be functional. This makes it much
easier to add regulator support to drivers since we don't require
that the machine integration for all systems using the device be
updated to provide regulators.
- Substantial reduction in the amount of busy waiting done while
waiting for enables to complete.
- Allow MFDs to distribute regulator supplies to child devices so we
don't have to expose the internal structure of MFDs outside of the
driver.
- Managed registeration for regulators.

Commit 1e29af62f2 ("mfd: Add refcounting
support to mfd_cells") had to drop the "const" keyword on the "cell"
parameter of mfd_add_devices(), as it added the refcounting pointers
to the objects of the passed mfd_cell array itself.
However, the mfd core code operates on copies of the mfd_cell objects,
so there's no need to modify the originally passed objects.
Hence, move the setting of the refcounting pointers from mfd_add_devices()
to mfd_platform_add_cell(), where the copy of the mfd_cell objects is made.
mfd_clone_cell() can just pass (a copy of) the original usage_count
pointer.
This allows to make the "cell" parameter of mfd_add_devices() "const"
again, and avoids future race conditions when registering multiple
instances of the same device in parallel.

Most of this branch consists of updates, additions and general churn of
the device tree source files in the kernel (arch/arm/boot/dts). Besides
that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board files
for various platforms.
- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
- Some updates to pinctrl and other subsystems. Most of these are for
DT-enablement of the various platforms and acks have been collected.

In some platforms, specially Thinkpad series, rts5249 won't be
initialized properly. So we need adjust some phy parameters to
improve the compatibility issue.
It is a little different between simulation and real chip. We have
no idea about which configuration is better before tape-out. We set
default settings according to simulation, but need to tune these
parameters after getting the real chip.
I can't explain every change in detail here. The below information is
just a rough description:
PHY_REG_REV: Disable internal clkreq_tx, enable rx_pwst
PHY_BPCR: No change, just turn the magic number to macro definitions
PHY_PCR: Change OOBS sensitivity, from 60mV to 90mV
PHY_RCR2: Control charge-pump current automatically
PHY_FLD4: Use TX cmu reference clock
PHY_RDR: Change RXDSEL from 30nF to 1.9nF
PHY_RCR1: Change the duration between adp_st and asserting cp_en from
0.32 us to 0.64us

The old timeout value was based on the assumption that the minimum values are

Occasionally, it is useful to map supplies from a child device onto the
MFD device. A typical usecase for this would be if the MFD device is
represented as a single node in device tree. All supplies will be
defined in device tree as existing on the MFD device. When a child
depends on frameworks which might have no knowledge of MFD to lookup
supplies on its behalf the supply will not be found.
This patch adds a list of supplies that should be looked up on the
parent rather than the child as part of the mfd_cell structure.

A number of new drivers and some new functionality + a lot of cleanups
all over IIO.
New Core Elements
1) New INT_TIME info_mask element for integration time, which may have
different effects on measurement noise and similar, than an amplifier
and hence is different from existing SCALE. Already existed in some
drivers as a custom attribute.
2) Introduce a iio_push_buffers_with_timestamp helper to cover the common
case of filling the last 64 bits of data to be passed to the buffer with
a timestamp. Applied to lots of drivers. Cuts down on repeated code and
moves a slightly fiddly bit of logic into a single location.
3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support
of elements such as sampling_frequency which is typically shared by all
input channels on a device. This reduces code and makes these controls
available from in kernel consumers of IIO devices.
New drivers
1) MCP3422/3/4 ADC
2) TSL4531 ambient light sensor
3) TCS3472/5 color light sensor
4) GP2AP020A00F ambient light / proximity sensor
5) LPS001WP support added to ST pressure sensor driver.
New driver functionality
1) ti_am335x_adc Add buffered sampling support.
This device has a hardware fifo that is fed directly into an IIO kfifo
buffer based on a watershed interrupt. Note this will act as an example
of how to handle this increasingly common type of device.
The only previous example - sca3000 - take a less than optimal approach
which is largely why it is still in staging.
A couple of little cleanups for that new functionality followed later.
Core cleanups:
1) MAINTAINERS - Sachin actually brought my email address up to date because
I said I'd do it and never got around to it :)
2) Assign buffer list elements as single element lists to simplify the
iio_buffer_is_active logic.
3) wake_up_interruptible_poll instead of wake_up_interruptible to only wake
up threads waiting for poll notifications.
4) Add O_CLOEXEC flag to anon_inode_get_fd call for IIO event interface.
5) Change iio_push_to_buffers to take a void * pointer so as to avoid some
annoying and unnecessary type casts.
6) iio_compute_scan_bytes incorrectly took a long rather than unsigned long.
7) Various minor tidy ups.
Driver cleanups (in no particular order)
1) Another set of devm_ allocations patches from Sachin Kamat.
2) tsl2x7x - 0 to NULL cleanup.
3) hmc5843 - fix missing > in MODULE_AUTHOR
4) Set of strict_strto* to kstrto* conversions.
5) mxs-lradc - fix ordering of resource removal to match creation
6) mxs-lradc - add MODULE_ALIAS
7) adc7606 - drop a work pending test duplicated in core functions.
8) hmc5843 - devm_ allocation patch
9) Series of redundant breaks removed.
10) ad2s1200 - pr_err -> dev_err
11) adjd_s311 - use INT_TIME
12) ST sensors - large set of cleanups from Lee Jones and removed restriction
to using only triggers provided by the st_sensors themselves from
Dennis Ciocca.
13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all.
14) tcs3472 - fix incorrect buffer size and wrong device pointer used in
suspend / resume functions.
15) max1363 - use defaults for buffer setup ops as provided by the triggered
buffer helpers as they are the same as were specified in max1363 driver.
16) Trivial tidy ups in a number of other drivers.

Previously the driver had only one-shot reading functionality.
This patch adds continuous sampling support to the driver.
Continuous sampling starts when buffer is enabled.
HW IRQ wakes worker thread that pushes samples to userspace.
Sampling stops when buffer is disabled by userspace.
Patil Rachna (TI) laid the ground work for ADC HW register access.
Russ Dill (TI) fixed bugs in the driver relevant to FIFOs and IRQs.
I fixed channel scanning so multiple ADC channels can be read
simultaneously and pushed to userspace.
Restructured the driver to fit IIO ABI.
And added INDIO_BUFFER_HARDWARE mode.

Merge tag 'pinctrl-v3.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control changes from Linus Walleij:
"Here is the bulk of pin control changes for the v3.12 series. Most of
the relevant information is in the tag.
I merged in v3.11-rc7 last week to get rid of a largeish conflict
within the sunxi (AllWinner) driver in linux-next and fix up the
non-trivial merge the right way. That driver had a rather large fix
adding locking late in the release cycle.
Overall the bulk changes this time is cleanups and refactorings and
not much new features, which is nice.

Rather then open coding a cache of the vibra control registers use the
regmap cache code. Also cache the interrupt mask register, providing
a small performance improvement for the interrupt code.
