additional devices to be specified in the Device Tree topology.
This support is implemented in the same driver as the GPIO

The addition of this support does not change the existing gpio

Default MPP configuration can be specified in the Device Tree

in the Device Tree will assume its default configuration.
It's also possible to configure an MPP at runtime using the

is not supported by the underlying hardware pin, then that
particular request is silently dropped with no error. This allows
for gpio users to continue specifying only a subset of the full

Since we support multiple device_nodes per spmi_device when used
with the spmi-dev-container flag, it's often unclear how a driver
should make reference to a particular device. Therefore,
introduce the spmi specific binding spmi-dev-name that specifies
the device name for the device_node.
Also introduce an API that can be used from
the driver to lookup the specific device node associated with a
particular device name.
Note that it may seem at first glance that the binding 'label' is
redundant with device_node->name. However, per the ePAPR,
device_node->name is intended to be as generic as possible,
representing the function of the device and not the precise
programming model. 'label' is used to give a platform
specific name that can be queried from device drivers.

reg-names and interrupt-names are standard bindings to map device
tree reg and interrupt indices to particular names. This way the
driver does not need to be concerned with hard coded assignments.
Therefore, add spmi support for these bindings.
Explicit support for reg-names is required since the
implementation does not make use of of_address_to_resource(),
which happens to already support this.
This is because of_address_to_resource() mandates address
translation, which is not relevant to spmi.
interrupt-names is already implicitly handled by
of_irq_to_resource(), which is used in the spmi implementation.
Add additional documentation to state clearly that this binding
is also supported.
Also add supporting routines to easily lookup a resource by name
for both registers and interrupts.

[sboyd: Squash in DT binding document]
Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
The spmi-dev-container binding is intended for SPMI
configurations that have multiple device nodes associated with
only one spmi_device. By default, if this flag is not specified,
each device node will create a new spmi_device.
Sometimes having multiple spmi_devices for SPMI device nodes is
superfluous. One example of this is gpios. In some architectures,
a single gpio is treated as a unique device. But from a gpio_chip
perspective, the chip is comprised of many gpios. Beyond wasting
memory allocating a unique spmi_device per gpio, the implication
of not coalescing spmi_devices is that the clients probe() routine
would be called N number of times. But this sort of behavior makes
it difficult to realize when a gpio_chip starts and stops. If we
assume that one gpio_chip represents one call to probe(), then
this problem is solved, since all gpios in that chip will be
passed as resources.
In order to support multiple device nodes per spmi_device, we
also need to extend the data structures for spmi_resources.
This change also makes an effort to cleanup some of the error
handling for illegal combinations of device bindings, as well as
adding some additional documentation.

Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and
is used to communication with one or more PMIC (slave) devices on the
SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the
SPMI controller that provides concurrent and autonomous PMIC access
to various entities that need to communicate with the PMIC.
The SPMI controller hardware handles all of the SPMI bus activity (bus
arbitration, sequence start condition, transmission of frames, etc).
This software driver uses the PMIC Arbiter register interface to
initiate command sequences on the SPMI bus. The status register is
read to determine when the command sequence has completed and whether
or not it completed successfully.
Request Capable Slave (RCS) devices can initiate a master write
command sequence on the SPMI bus that the can be decoded by the

This change adds SPMI Device Tree parsing. The
of_spmi_register_devices() API should be called from the probe()
routine of each SPMI controller to parse the subtree and add the
respective SPMI devices.
The SPMI subtree is nested up to two levels deep. The first level
is the most basic and treats the address as the SPMI slave ID.
This should be used for simple devices that has no notion of
segmented SPMI address spaces.
An optional second level specifies the address as an offset
within the outer layer's slave ID. This is used to specify
multiple devices on the same slave ID that have different address
ranges. In fact, it's reasonable to specify any number of address
ranges at this level.
Devices can also specify any number of interrupts that's decoding
is done by an external interrupt device.
Sections of this code were taken from drivers/of/platform.c.

spi_qsd: Fix for SPI Operational State Invalid error
This error is reproted randomly when the SPI core is put

When the timer expires, we check again to ensure that the

drivers: barriers: Replace dsb() with mb()
Replace explicit dsb() calls with mb(). Now that the
generic ARM implementation defines mb() to mean (at least)
dsb(), it is appropriate to switch back to the generic
kernel version of the barriers. This is also needed for
correctness on certain targets (such as 7x27) where dsb()
is insufficient and other operations (such as outer cache
sync or writing to strongly-ordered memory) are required to
ensure proper I/O operations ordering. In some cases,
remove explicit calls to outer_sync following a barrier
since the barrier will now have an explicit outer_sync
call.

there are no hardware limitations in doing so.

This adds MSM SPI controller driver. The driver is SPI master, and
allows slave connections. Current version of the driver supports
FIFO and DM modes chosen upon the message size. The driver also
supports loopback mode which can be used for testing purposes.
This is a squashed version of all the MSM SPI driver changes on the QuIC
MSM 2.6.29 kernel which can be found at www.codeaurora.org.
It also contains all relevant adaptations to SPI core changes in 2.6.32
kernel.

Add a gpio_chip driver to support the Qualcomm SPMI PMIC
architecture called QPNP. The driver supports Device Tree
and allows a device_node to be registered as a gpio-controller.
The driver also specifies APIs to allow a non-Device Tree user
the ability to configure the PMIC GPIOs.
This driver does not handle interrupts for GPIOs directly.
Instead, that work is handled by the existing qpnp-int driver.
This is feasible since the interrupt register map for all
QPNP peripherals is the same.

QUP (Qualcomm Universal Peripheral engine) hardware provides FIFO
based data path to mini cores like I2C. i2c-qup driver communicates
with the QUP and its FIFOs.
Advantages of this driver include 1-interrupt per FIFO/BLOCK number
of byte unlike 1-interrupt-per-byte of i2c-msm.
Since the QUP hardware communicates with I2C mini core, and this
driver communicates with QUP hardware, driver communicating with
I2C hardware directly (like i2c-msm) can't be used to communicate
with QUP. QUP has FIFO mode and BLOCK mode. FIFO mode can be used
if the data transfer size is less than FIFO size. BLOCK mode should
be used for transfers greater than FIFO size.
FIFO mode is supported in this initial implementation.

msm: Removed XPU violations.
During initialization, there is a violation in writing to
"read only" registers for targets that support trust zone.
Trustzone marks certain registers as read-only.
This change fixes the issue by writing to registers only
on targets that do not support trust zone.

Revert "msm: rng: Disable RNG init on APQ8064"
This reverts commit 46af59fb8f4bce302ad4d787b63b25e46548df6a.
The RNG driver was initially disabled because of missing clock
changes and this driver was causing boot up issues.
Now with the clock changes checked in the RNG driver works.

prng: Replace clk_enable and clk_disable APIs.
The clk driver has introduced new clock APIs that replace
the existing clk_enable and clk_disable.
-clk_enable() APIs is replaced with clk_prepare_enable().
-clk_disable() API is replaced with clk_disable_unprepare().

msm-rng: Fix PRNG_LFSR_CFG setup
Changes to only configure the LFSR on devices that don't have the
prng hardware already setup mistakenly removed the LFSR
configuration. Instead, the change is ORing in 1s into the top 16
bits of the register (they're marked as reserved).
Restore the original code by masking off the lower 16 bits of the
register and filling them with values from the
PRNG_LFSR_CFG_CLOCKS define.

A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
* Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
(adding back the include file on those for now)
* AT91 fixes for usb and spi
* smsc911x ethernet fixes for i.MX
* smsc911x fixes for OMAP
* gpio fixes for Tegra
* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for
Samsung platforms
In other words, more or less the regular collection of -rc1/2 type
material. A few of them, in particular the smsc911x for OMAP series, aren't
technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

that support Data Tag will provide increased throughput for metadata.
* Faster detection of card removal on I/O errors.
Drivers:
* dw_mmc now supports eMMC Power Off Notify, has PCI support, and
implements pre_req and post_req for asynchronous requests.
* omap_hsmmc now supports device tree.
* esdhc now has power management support.
* sdhci-tegra now supports Tegra30 devices.
* sdhci-spear now supports hibernation.
* tmio_mmc now supports using a GPIO for card detection.
* Intel PCH now supports 8-bit bus transfers.

Here is the first big update chunk of sound stuff for 3.4-rc1.
In the common sound infrastructure, there are a few changes for
dynamic PCM support (used in ASoC) and a few clean-ups. Majority of
changes are found, as usual, in HD-audio and ASoC.
Some highlights of HD-audio changes:
- All the long-standing static quirk codes for Realtek codec were
finally removed by fixing and extending the Realtek auto-parser.
- The mute-LED control is standardized over all HD-audio codec
drivers using the extended vmaster hook.
- The vmaster slave mixer elements are initialized to 0dB as default
so that the user won't be annoyed by the silent output after
updates, e.g. due to the additions of new elements.
- Other many fix-ups for the misc HD-audio devices.
In the ASoC side, this is a very active release, including a quite a
few framework enhancements. Some highlights:
- Support for widgets not associated with a CODEC, an important part
of the dynamic PCM framework.
- A library factoring out the common code shared by dmaengine based
DMA drivers contributed by Lars-Peter Clausen. This will save a lot
of code and make it much easier to deploy enhancements to
dmaengine.
- Support for binary controls, used for providing runtime
configuration of algorithm coefficients.
- A new DAPM widget type for regulator supplies allowing drivers for
devices that can power down unused supplies while active to do
without any per-driver code.
- DAPM widgets for DAIs, initially giving a speed boost for playback
startup and shutdown and also the basis for CODEC<->CODEC DAI link
support.
- Support for specifying the number of significant bits on audio
interfaces, useful for allowing applications to know how much effort
to put into generating data for a larger sample format.
- Conversion of the FSI driver used on some SH processors to
DMAEngine.
- Conversion of EP93xx drivers to DMAEngine.
- New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics
WM2200.
- Move audmux driver from arc/arm to sound/soc
- McBSP move from arch/ to sound/ and updates
Also, a few small updates and fixes for other drivers like au88x0,
ymfpci, USB 6fire, USB usx2yaudio are included.

Pull powerpc merge from Benjamin Herrenschmidt:
"Here's the powerpc batch for this merge window. It is going to be a
bit more nasty than usual as in touching things outside of
arch/powerpc mostly due to the big iSeriesectomy :-) We finally got
rid of the bugger (legacy iSeries support) which was a PITA to
maintain and that nobody really used anymore.
Here are some of the highlights:
- Legacy iSeries is gone. Thanks Stephen ! There's still some bits
and pieces remaining if you do a grep -ir series arch/powerpc but
they are harmless and will be removed in the next few weeks
hopefully.
- The 'fadump' functionality (Firmware Assisted Dump) replaces the
previous (equivalent) "pHyp assisted dump"... it's a rewrite of a
mechanism to get the hypervisor to do crash dumps on pSeries, the
new implementation hopefully being much more reliable. Thanks
Mahesh Salgaonkar.
- The "EEH" code (pSeries PCI error handling & recovery) got a big
spring cleaning, motivated by the need to be able to implement a
new backend for it on top of some new different type of firwmare.
The work isn't complete yet, but a good chunk of the cleanups is
there. Note that this adds a field to struct device_node which is
not very nice and which Grant objects to. I will have a patch soon
that moves that to a powerpc private data structure (hopefully
before rc1) and we'll improve things further later on (hopefully
getting rid of the need for that pointer completely). Thanks Gavin
Shan.
- I dug into our exception & interrupt handling code to improve the
way we do lazy interrupt handling (and make it work properly with
"edge" triggered interrupt sources), and while at it found & fixed
a wagon of issues in those areas, including adding support for page
fault retry & fatal signals on page faults.
- Your usual random batch of small fixes & updates, including a bunch
of new embedded boards, both Freescale and APM based ones, etc..."
I fixed up some conflicts with the generalized irq-domain changes from
Grant Likely, hopefully correctly.

This has been a fairly quiet release from a regulator point of view, the
only real framework features added were devm support and a convenience
helper for setting up fixed voltage regulators.
We also added a couple of drivers (but will drop the BQ240022 driver via
the arm-soc tree as it's been replaced by the more generic
gpio-regulator driver) and Axel Lin continued his relentless and
generally awesome stream of fixes and cleanups.

...
Fix up fairly trivial conflicts in drivers/isdn/gigaset/interface.c and
drivers/net/usb/{Kconfig,qmi_wwan.c} as per David.
Conflicts:
arch/arm/mach-lpc32xx/clock.c
arch/arm/mach-pxa/pxa25x.c
arch/arm/mach-pxa/pxa27x.c
The conflicts with pxa are non-obvious, we have multiple branches
adding and removing the same clock settings. According to
Haojian Zhuang, removing the sa1100 rtc dummy clock is the correct
fix here.
