Pull ARM updates from Russell King:
- Major clean-up of the L2 cache support code. The existing mess was
becoming rather unmaintainable through all the additions that others
have done over time. This turns it into a much nicer structure, and
implements a few performance improvements as well.
- Clean up some of the CP15 control register tweaks for alignment
support, moving some code and data into alignment.c
- DMA properties for ARM, from Santosh and reviewed by DT people. This
adds DT properties to specify bus translations we can't discover
automatically, and to indicate whether devices are coherent.
- Hibernation support for ARM
- Make ftrace work with read-only text in modules
- add suspend support for PJ4B CPUs
- rework interrupt masking for undefined instruction handling, which
allows us to enable interrupts earlier in the handling of these
exceptions.
- support for big endian page tables
- fix stacktrace support to exclude stacktrace functions from the
trace, and add save_stack_trace_regs() implementation so that kprobes
can record stack traces.
- Add support for the Cortex-A17 CPU.
- Remove last vestiges of ARM710 support.
- Removal of ARM "meminfo" structure, finally converting us solely to
memblock to handle the early memory initialisation.

The DSI controllers are powered by a (typically 1.2V) regulator. Usually
this is always on, so there was no need to support enabling or disabling
it thus far. But in order not to consume any power when DSI is inactive,
give the driver a chance to enable or disable the supply as needed.

Revert commit 18ebc0f404 "drm/tegra: hdmi: Enable VDD earlier for
hotplug/DDC" and instead add a new supply for the +5V pin on the HDMI
connector.
The vdd-supply property refers to the regulator that supplies the
AVDD_HDMI input on Tegra, rather than the +5V HDMI connector pin. This
was never a problem before, because all boards had that pin hooked up to
a regulator that was always on. Starting with Dalmore and continuing
with Venice2, the +5V pin is controllable via a GPIO. For reasons
unknown, the GPIO ended up as the controlling GPIO of the AVDD_HDMI
supply in the Dalmore and Venice2 DTS files. But that's not correct.
Instead, a separate supply must be introduced so that the +5V pin can be
controlled separately from the supplies that feed the HDMI block within
Tegra.
A new hdmi-supply property is introduced that takes the place of the
vdd-supply and vdd-supply is only enabled when HDMI is enabled rather
than all the time.

was a pretty active cycle for KVM. Changes include:
- a lot of s390 changes: optimizations, support for migration,
GDB support and more
- ARM changes are pretty small: support for the PSCI 0.2 hypercall
interface on both the guest and the host (the latter acked by Catalin)
- initial POWER8 and little-endian host support
- support for running u-boot on embedded POWER targets
- pretty large changes to MIPS too, completing the userspace interface
and improving the handling of virtualized timer hardware
- for x86, a larger set of changes is scheduled for 3.17. Still,
we have a few emulator bugfixes and support for running nested
fully-virtualized Xen guests (para-virtualized Xen guests have
always worked). And some optimizations too.
The only missing architecture here is ia64. It's not a coincidence
that support for KVM on ia64 is scheduled for removal in 3.17.

Pull KVM updates from Paolo Bonzini:
"At over 200 commits, covering almost all supported architectures, this
was a pretty active cycle for KVM. Changes include:
- a lot of s390 changes: optimizations, support for migration, GDB
support and more
- ARM changes are pretty small: support for the PSCI 0.2 hypercall
interface on both the guest and the host (the latter acked by
Catalin)
- initial POWER8 and little-endian host support
- support for running u-boot on embedded POWER targets
- pretty large changes to MIPS too, completing the userspace
interface and improving the handling of virtualized timer hardware
- for x86, a larger set of changes is scheduled for 3.17. Still, we
have a few emulator bugfixes and support for running nested
fully-virtualized Xen guests (para-virtualized Xen guests have
always worked). And some optimizations too.
The only missing architecture here is ia64. It's not a coincidence
that support for KVM on ia64 is scheduled for removal in 3.17"

The Allwinner sunxi mmc host uses dma in bus-master mode using a built-in
designware idmac controller, which is identical to the one found in the mmc-dw
hosts. However the rest of the host is not identical to mmc-dw, it deals with
sending stop commands in hardware which makes it significantly different
from the mmc-dw devices.

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

For this release SPI has been exceptionally quiet, all the work has been
on improving drivers (including taking advantage of some of the recent
framework updates):
- DMA support for the rspi driver providing a nice performance boost.
- Performance improvement for the SIRF controller in PIO mode.
- New support for the Cadence SPI IP and for pxa2xx on BayTrail.

development cycle:
- Antoine Tenart made the get_group_pins() vtable entry
optional.
- Antoine also provides an entirely new driver for the
Marvell Berlin SoC. This is unrelated to the existing
MVEBU hardware driver and warrants its own separate
driver.
- Reflected from the GPIO subsystem there is a number of
refactorings to make pin control drivers with gpiochips
use the new gpiolib irqchip helpers. The following
drivers were converted to use the new infrastructure:
- ST Microelectronics STiH416 and friends
- The Atmel AT91
- The CSR SiRF (Prima2)
- The Qualcomm MSM series
- Massive improvements in the Qualcomm MSM driver from
Bjorn Andersson, Andy Gross and Kumar Gala. Among those
new support for the IPQ8064 and MSM8x74 SoC variants.
- Support for the Freescale i.MX6 SoloX SoC variant.
- Massive improvements in the Allwinner sunxi driver from
Boris Brezillon, Maxime Ripard and Chen-Yu Tsai.
- Renesas PFC updates from Laurent Pinchart, Kuninori
Morimoto, Wolfram Sang and Magnus Damm.
- Cleanups and refactorings of the nVidia Tegra driver from
Stepgen Warren.
- The Exynos driver now supports the Exynos3250 SoC.
- Intel BayTrail updates from Jin Yao, Mika Westerberg.
- The MVEBU driver now supports the Orion5x SoC
variants, which is part of the effort of getting rid of
the old Marvell kludges in arch/arm/mach-orion5x
- Rockchip driver updates from Heiko Stuebner.
- A ton of cleanups and janitorial patches from Axel Lin.
- Some minor fixes and improvements here and there.

Here is the big USB driver pull request for 3.16-rc1.
Nothing huge here, but lots of little things in the USB core, and in
lots of drivers. Hopefully the USB power management will be work better
now that it has been reworked to do per-port power control dynamically.
There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
is finally gone now that everything has been converted over to the
dynamic debug inteface, the last hold-out drivers were cleaned up and
the config option removed. There were also other minor things all
through the drivers/usb/ tree, the shortlog shows this pretty well.
All have been in linux-next, including the very last patch, which came
from linux-next to fix a build issue on some platforms.

The glue around the core designware IP is significantly different between
the Exynos and i.MX implementation, which is reflected in the DT bindings.
This changes the i.MX6 binding to reuse as much as possible from the common
designware binding and removes old cruft.
I removed the optional GPIOs with the following reasoning:
- disable-gpio: endpoint specific GPIO, not currently wired up in any code.
Should be handled by the PCI device driver, not the host controller
driver.
- wake-up-gpio: same as above.
- power-on-gpio: No user in any upstream DT. This should be handled by a
regulator which shouldn't be controlled by the host driver, but rather by
the PCI device driver.

ASoC: Final updates for v3.16
A few more updates from the last week of development, nothing too
exciting. Highlights include:
- GPIO descriptor support for jacks
- More updates and fixes to the Freescale SSI, Intel and rsnd drivers.
- New drivers for Analog Devices ADAU1361, ADAU1381, ADAU1761 and
ADAU1781, and Realtek RT5677.
The Keystone II devices have a set of registers that are used to control
the status of its peripherals. This node is intended to allow access to
this functionality.

On ARM Chromebooks we have a few devices that are accessed by both the
AP (the main "Application Processor") and the EC (the Embedded
Controller). These are:
* The battery (sbs-battery).
* The power management unit tps65090.
On the original Samsung ARM Chromebook these devices were on an I2C
bus that was shared between the AP and the EC and arbitrated using
some extranal GPIOs (see i2c-arb-gpio-challenge).
The original arbitration scheme worked well enough but had some
downsides:
* It was nonstandard (not using standard I2C multimaster)
* It only worked if the EC-AP communication was I2C
* It was relatively hard to debug problems (hard to tell if i2c issues
were caused by the EC, the AP, or some device on the bus).
On the HP Chromebook 11 the design was changed to:
* The AP/EC comms were still i2c, but the battery/tps65090 were no
longer on the bus used for AP/EC communication. The battery was
exposed to the AP through a limited i2c tunnel and tps65090 was
exposed to the AP through a custom Linux driver.
On the Samsung ARM Chromebook 2 the scheme is changed yet again, now:
* The AP/EC comms are now using SPI for faster speeds.
* The EC's i2c bus is exposed to the AP through a full i2c tunnel.
The upstream "tegra124-venice2" uses the same scheme as the Samsung
ARM Chromebook 2, though it has a different set of components on the
other side of the bus.
This driver supports the scheme used by the Samsung ARM Chromebook 2.
Future patches to this driver could add support for the battery tunnel
on the HP Chromebook 11 (and perhaps could even be used to access
tps65090 on the HP Chromebook 11 instead of using a special driver,
but I haven't researched that enough).

In certain boards the source for the clk32k clock can be gated. In these
boards the clk32k clock can be provided to the driver and it is going to be
enabled/disabled when it is needed.
If the clk32k clock is not provided the driver will assume that it is always
running.

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

The bulk of this branch is updates for Renesas Shmobile. They are still
doing some enablement for classic boards first, and then come up with DT
bindings when they've had a chance to learn more about the hardware. Not
necessarily a bad way to go about it, and they're looking at moving some
of the temporary board code resulting from it to drivers/staging instead
to avoid the churn here.
As a result of the shmobile clock cleanups, we end up merging quite a
bit of SH code here as well. We ended up merging it here instead of in
the cleanup branch due to the other board changes depending on it.

- We are finalizing and fixing up the gpiochip irqchip helpers
bringing a helpful irqchip implementation into the gpiolib
core and avoiding duplicate code and, more importantly,
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
regulator functions for cases where the use of GPIO
is optional and not strictly required.
- Make of_get_named_gpiod_flags() private - we do not
want to unnecessarily expose APIs to drivers that
make the gpiolib harder than necessary to maintain
and refactor. Privatize this function.
- Support "-gpio" suffix for the OF GPIO retrieveal path.
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
gpiochips that sleep.
- Tons of cleanups and janitorial work from Jingoo Han,
Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe.
Notably Jingoo cut off a ton of pointless OOM messages.
- Incremental development and fixes for various drivers,
nothing really special here.

Exynos drm hdmi driver used to get dummy hdmiphy clock to
control the PMU bit for hdmiphy. This bit needs to be set
before setting any resolution to hdmi hardware. This was
handled using dummy hdmiphy clock which is removed here.
PMU is already defined as system controller for exynos
SoCs. Hdmi driver is modified to control the phy enable bit
inside PMU using regmap interfaces.

Certain bridge chips use a GPIO to indicate the cable status instead
of the I_DP_HPD pin. This adds an optional device-tree property,
"samsung,hpd-gpio", to the exynos-dp controller which indicates that
the specified GPIO should be used for hotplug detection.
The GPIO is then set up as an edge-triggered interrupt where the
rising edge indicates hotplug-in and the falling edge indicates hotplug-out.

====================
Please pull this batch of updates intended for 3.16...
For the mac80211 bits, Johannes says:
"Here I just have Heikki's rfkill GPIO cleanups.
The ARM/tegra patch is OK with the maintainer (Stephen). Let me know of
any problems."
and;
"We have a whole bunch of work on CSA by Andrei, Luca and Michal, but
unfortunately it doesn't seem quite complete yet so it's still disabled.
There's some TDLS work from Arik, and the rest is mostly minor fixes and
cleanups."
For the NFC bits, Samuel says:
"This is the NFC pull request for 3.16. We have:
- STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and
thus relies on the HCI stack. This submission provides support for tag
redaer/writer mode (including Type 5) and device tree bindings.
- PM runtime support and a bunch of bug fixes for TI's trf7970a.
- Device tree support for NXP's pn544. Legacy platform data support is
obviously kept intact.
- NFC Tag type 4B support to the NFC Digital stack.
- SOCK_RAW type support to the raw NFC socket, and allow NCI
sniffing from that. This can be extended to report HCI frames and also
proprietarry ones like e.g. the pn533 ones."
For the iwlwifi bits, Emmanuel says:
"Eran continues to work on new devices, Eyal is still digging in
the rate control stuff, and Johannes added new functionality to the
debug system we have in place now along with a few cleanups he made
on the way. That's pretty much it."
and;
"Avri continues to work on the power code and Eran is improving the
NVM handling as a preparations for new devices on which he works
with Liad. Luca cleans up a bit the code while working on CSA. I have
the regular BT Coex stuff and a small lockdep fix. Johannes has his
regular amount of clean ups and improvements, the main one is the
ability to leave 2 chains open to improve diversity and hence the
throughput in high attenuation scenarios."
and;
"The regular amount of housekeeping here. I merged iwlwifi-fixes.git to
be able to add the patch you didn't want in wireless.git at that stage
of the -rc cycle. Luca has a few preparations for CSA implementation
and also what seems to be a bugfix for P2P but hasn't caused issues
we could notice."
For the Atheros bits, Kalle says:
"For ath10k Michal did various small fixes on how we handle
hardware/firmware problems and he also fixed two memory leaks."
Also included are a couple of pulls from the wireless tree to
avoid/resolve merge issues...

Add support for a generic PCI host controller, such as a
firmware-initialised device with static windows or an emulation by
something such as kvmtool.
The controller itself has no configuration registers and has its address
spaces described entirely by the device-tree (using the bindings from
ePAPR). Both CAM and ECAM are supported for Config Space accesses.
Add corresponding documentation for the DT binding.

- From Daniel Lezcano:
This patchset relies on the cpm_pm notifier to initiate the
powerdown sequence operations from pm.c instead cpuidle.c.
Thus the cpuidle driver is no longer dependent from arch
specific code as everything is called from the pm.c file.
Note, this is based on tags/exnos-mcpm and tags/samsung-clk

This patchset relies on the cpm_pm notifier to initiate the
powerdown sequence operations from pm.c instead cpuidle.c.
Thus the cpuidle driver is no longer dependent from arch
specific code as everything is called from the pm.c file.

"7408484 usb: gadget: s3c-hsotg: enable generic phy support" introduces
generic phy support to the dwc2.txt binding and the s3c-hsotg driver
which implements support for the binding. The binding documentation
incorrectly states that the phy-names property will be "device". The
binding example, driver, and one dts user all implement the phy-names
property as requiring "usb2-phy".
Fix the dwc2.txt binding documentation to correctly specify "usb2-phy"
as the appropriate value for phy-names.

Audio Tracking Logic is designed to be used by HD Radio applications to
synchronize the audio output clocks to the baseband clock. ATL can be also
used to track errors between two reference clocks (BWS, AWS) and generate a modulated
clock output which averages to some desired frequency.
In essence ATL is generating a clock to be used by an audio codec and also
to be used by the SoC as MCLK.
To be able to integrate the ATL provided clocks to the clock tree we need
two types of DT binding:
- DT clock nodes to represent the ATL clocks towards the CCF
- binding for the ATL IP itself which is going to handle the hw
configuration
The reason for this type of setup is that ATL itself is a separate device
in the SoC, it has it's own address space and clock domain. Other IPs can
use the ATL generated clock as their functional clock (McASPs for example)
and external components like audio codecs can also use the very same clock
as their MCLK.
The ATL IP in DRA7 contains 4 ATL instences.

These settings are based on the "Recommended Sleep Sequences for
the Zoom Platform".
The settings assume most of the regulators are under control of
Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as
Linux cannot do it.
For any board specific changes to these, let's patch them in as
changes to the generic data in the follow-up patches. This keeps
the board specific changes small.
Note that this does not consider the twl5030 errata 27 and 28.
That can be added later on after it has been tested. For more
information about errata 27 and 28.

The twl4030 PMIC needs to be configured properly for things like
warm reset and deeper idle states so the PMIC manages the regulators
properly based on the hardware triggers from the SoC. Earlier
we have configured twl4030 using platform data, but we want to
do it for device tree based booting also.
In some cases configuring twl4030 is needed for things to work.
For example, when rebooting an OMAP3530 at 125 MHz, it hangs.
With this patch, TWL4030 will be reset when a warm reset occures,
and OMAP3530 does not hang on reboot.
Let's add device tree support and configure things for warm reset
as the default when compatible = "ti,twl4030-power". More
complicated configurations can be added to the driver based on
other compatible flags.
Note we now also make the pdata const like it should be.

USB3503 chip supports 8 values of reference clock. The value is
specified by REF_SEL[1:0] pins and INT_N line. This patch add support
for getting 'refclk' clock, enabling it and setting INT_N line according
to the value of the gathered clock. If no clock has been specified,
driver defaults to the old behaviour (assuming that clock has been
specified by REF_SEL pins from primary reference clock frequencies
table).

On the Allwinner's A31 SoC the reset line connected to the EHCI IP has to
be deasserted for the EHCI block to be usable.
Add support for an optional reset controller that will be deasserted on
power off and asserted on power on.

This commit extends the compatible string list of the xhci-platform
binding with the new "armada-375-xhci" and "armada-380-xhci"
compatible strings. It is used to describe the XHCI controller which
is available in the Armada 375 and 38x SoCs.
It also indicates that an optional 'clocks' property is now supported.
