Pull staging driver updates from Greg KH:
"Here's the big staging driver update for 4.4-rc1. If you were
disappointed for 4.3-rc1 that we didn't contribute enough changesets,
you should be happy with this pull request of over 2400 patches.
But overall we removed more lines of code than we added, which is nice
to see. Full details in the shortlog.
All of these have been in linux-next for a while"
Greg, I've never been disappointed in how few commits Staging

Pull arm64 updates from Catalin Marinas:
- "genirq: Introduce generic irq migration for cpu hotunplugged" patch
merged from tip/irq/for-arm to allow the arm64-specific part to be
upstreamed via the arm64 tree
- CPU feature detection reworked to cope with heterogeneous systems
where CPUs may not have exactly the same features. The features
reported by the kernel via internal data structures or ELF_HWCAP are
delayed until all the CPUs are up (and before user space starts)
- Support for 16KB pages, with the additional bonus of a 36-bit VA
space, though the latter only depending on EXPERT
- Implement native {relaxed, acquire, release} atomics for arm64
- New ASID allocation algorithm which avoids IPI on roll-over, together
with TLB invalidation optimisations (using local vs global where
feasible)
- KASan support for arm64
- EFI_STUB clean-up and isolation for the kernel proper (required by
KASan)
- copy_{to,from,in}_user optimisations (sharing the memcpy template)
- perf: moving arm64 to the arm32/64 shared PMU framework
- L1_CACHE_BYTES increased to 128 to accommodate Cavium hardware
- Support for the contiguous PTE hint on kernel mapping (16 consecutive
entries may be able to use a single TLB entry)
- Generic CONFIG_HZ now used on arm64
- defconfig updates

Pull ARM updates from Russell King:
"In this ARM merge, we remove more lines than we add. Changes include:
- Enable imprecise aborts early, so that bus errors aren't masked
until later in the boot. This has the side effect that boot
loaders which provoke these aborts can cause the kernel to crash
early in boot, so we install a handler to report this event around
the site where these are enabled.
- Remove the buggy but impossible to enable cmpxchg syscall code.
- Add unwinding annotations to some assembly code.
- Add support for atomic half-word exchange for ARMv6k+.
- Reduce ioremap() alignment for SMP/LPAE cases where we don't need
the large alignment.
- Addition of an "optimal" 3G configuration for systems with 1G of
RAM.
- Increase vmalloc space by 128M.
- Constify some SMP operations structures, which have never been
writable.
- Improve ARMs dma_mmap() support for mapping DMA coherent mappings
into userspace.
- Fix to the NMI backtrace code in the IPI case on ARM where the
failing CPU gets stuck for 10s waiting for its own IPI to be
delivered.

This patch adds device tree support for the netxbig LEDs.
This also introduces a additionnal DT binding for the GPIO extension bus
(netxbig-gpio-ext) used to configure the LEDs. Since this bus could also
be used to control other devices, then it seems more suitable to have it
in a separate DT binding.

Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for the v4.4 development cycle.
The only changes hitting outside drivers/gpio are in the pin control
subsystem and these seem to have settled nicely in linux-next.
Development mistakes and catfights are nicely documented in the
reverts as you can see. The outcome of the ABI fight is that we're
working on a chardev ABI for GPIO now, where hope to show results for
the v4.5 kernel.
Summary of changes:
GPIO core:
- Define and handle flags for open drain/open collector and open
source/open emitter, also know as "single-ended" configurations.
- Generic request/free operations that handle calling out to the
(optional) pin control backend.
- Some refactoring related to an ABI change that did not happen, yet
provide useful.
- Added a real-time compliance checklist. Many GPIO chips have
irqchips, and need to think this over with the RT patches going
upstream.
- Restructure, fix and clean up Kconfig menus a bit.
New drivers:
- New driver for AMD Promony.
- New driver for ACCES 104-IDIO-16, a port-mapped I/O card,
ISA-style. Very retro.
Subdriver changes:
- OMAP changes to handle real time requirements.
- Handle trigger types for edge and level IRQs on PL061 properly. As
this hardware is very common it needs to set a proper example for
others to follow.
- Some container_of() cleanups.
- Delete the unused MSM driver in favor of the driver that is
embedded inside the pin control driver.
- Cleanup of the ath79 GPIO driver used by many, many OpenWRT router
targets.
- A consolidated IT87xx driver replacing the earlier very specific
IT8761e driver.
- Handle the TI TCA9539 in the PCA953x driver. Also handle ACPI
devices in this subdriver.
- Drop xilinx arch dependencies as these FPGAs seem to profilate over
a few different architectures. MIPS and ARM come to mind"

Pull pin control updates from Linus Walleij:
"This is the big bulk of pin control changes for the v4.4 kernel
development cycle. Development pace is high in pin control again this
merge window. 28 contributors, 83 patches.
It hits a few sites outside the pin control subsystem:
- Device tree bindings in Documentation (as usual)
- MAINTAINERS
- drivers/base/* for the "init" state handling by Doug Anderson.
This has been ACKed by Greg.
- drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
in the USB subsystem. This has been ACKed by both Greg and Felipe.
- arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
through the ARM SoC tree but ended up here.
This time I am using Geert Uytterhoeven as submaintainer for SH PFC
since the are three-four people working in parallel with new Renesas
ASICs.
Summary of changes:
Infrastructure:
- Doug Anderson wrote a patch adding an "init" state different from
the "default" state for pin control state handling in the core
framework. This is applied before the driver's probe() call if
defined and takes precedence over "default". If both are defined,
"init" will be applied *before* probe() and "default" will be
applied *after* probe().
Significant subdriver improvements:
- SH PFC is switched to getting GPIO ranges from the device tree
ranges property on DT platforms.
- Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized.
- Got rid of SH PFC hardcoded IRQ numbers.
- Allwinner sunxi external interrupt through the "r" controller.
- Moved the Cygnus driver to use DT-provided GPIO ranges.
New drivers:
- Atmel PIO4 pin controller for the SAMA4D2 family
New subdrivers:
- Rockchip RK3036 subdriver
- Renesas SH PFC R8A7795 subdriver
- Allwinner sunxi A83T PIO subdriver
- Freescale i.MX7d iomux lpsr subdriver
- Marvell Berlin BG4CT subdriver
- SiRF Atlas 7 step B SoC subdriver
- Intel Broxton SoC subdriver
Apart from this, the usual slew if syntactic and semantic fixes"

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-next
Samuel Ortiz says:
====================
NFC 4.4 pull request
This is the NFC pull request for 4.4.
It's a bit bigger than usual, the 3 main culprits being:
- A new driver for Intel's Fields Peak NCI chipset. In order to
support this chipset we had to export a few NCI routines and
extend the driver NCI ops to not only support proprietary
commands but also core ones.
- Support for vendor commands for both STM drivers, st-nci
and st21nfca. Those vendor commands allow to run factory tests
through the NFC netlink interface.
- New i2c and SPI support for the Marvell driver, together with
firmware download support for this driver's core.
Besides that we also have:
- A few file renames in the STM drivers, to keep the naming
consistent between drivers.
- Some improvements and fixes on the NCI HCI layer, mostly to
properly reach a secure element over a legacy HCI link.
- A few fixes for the s3fwrn5 and trf7970a drivers.

In order to align with st21nfca, dts configuration properties
ese_present and uicc_present are made available in st-nci driver.
So far, in early development firmware, because
nci_nfcee_mode_set(DISABLE) was not supported we had to try to
enable it during the secure element discovery phase.
After several trials on commercial and qualified firmware it appears
that nci_nfcee_mode_set(ENABLE) and nci_nfcee_mode_set(DISABLE) are
properly supported.
Such feature also help us to eventually save some time (~5ms) when
only one secure element is connected.

The "compatible" property text contradicts even the example given in the MMCIF
binding document itself; moreover, the Renesas MMCIF driver only matches on
the generic "compatible" string and doesn't look for the SoC specific strings
at all. Thus describe "renesas,sh-mmcif" as a fallback value.

Add ciu_drive, ciu_sample clocks and default-sample-phase. This will later
be used by tuning code.
We do not touch ciu_drive (and by extension define default-drive-phase).
Drive phase is mostly used to define minimum hold times, while one could
write some code to determine what phase meets the minimum hold time
(ex 10 degrees) this will not work with the current clock phase framework
(which floors angles, so we'll get 0 deg, and there's no way to know what
resolution the floors happen at). We assume that the default drive angles
set by the hardware are good enough.

usb: patches for v4.4 merge window
This pull request is large with a total of 136 non-merge
commits. Because of its size, we will only describe the big things in
broad terms.
Many will be happy to know that dwc3 is now almost twice as fast after
some profiling and speed improvements. Also in dwc3, John Youn from
Synopsys added support for their new DWC USB3.1 IP Core and the HAPS
platform which can be used to validate it.
A series of patches from Robert Baldyga cleaned up uses of
ep->driver_data as a flag for "claimed endpoint" in favor of the new
ep->claimed flag.
Sudip Mukherjee fixed a ton of really old problems on the amd5536udc
driver. That should make a few people happy.
Heikki Krogerus worked on converting dwc3 to the unified device property
interface.
Together with these, there's a ton of non-critical fixes, typos and
stuff like that.

This change adds functionality to operate on reserved SRAM partitions
described in device tree file. Two partition properties are added,
"pool" and "export", the first one allows to share a specific partition
for usage by a kernel consumer in the same manner as it is done for
the whole SRAM device, and "export" property provides access to some
SRAM area from userspace over sysfs interface. Practically it is
possible to specify both properties for an SRAM partition, however
simultaneous access from a kernel consumer and from userspace is not
serialized, but still the combination may be useful for debugging
purpose.
The change opens the following scenarios of SRAM usage:
* updates in a particular SRAM area specified by offset and size are
done by bootloader, then this information is utilized by the kernel,
* a particular SRAM area is rw accessed from userspace, the stored
data is persistent on soft reboots,
* a device driver secures SRAM area for its purposes,
* etc.
Note, strictly speaking the added optional properties describe policy
of SRAM usage, rather than hardware, but here the policy mostly
resembles flash partitions in devicetree, which is undoubtedly
a very popular option but it does not describe hardware.
