Merge drm updates from Dave Airlie:
 "This is the main drm pull request for 4.8.

  I'm down with a cold at the moment so hopefully this isn't in too bad
  a state, I finished pulling stuff last week mostly (nouveau fixes just
  went in today), so only this message should be influenced by illness.
  Apologies to anyone who's major feature I missed :-)

  Core:

043248cd4e ARM: DT updates for v4.8 
Device tree contents continue to be the largest branches we submit. This
 time around, some of the contents worth pointing out is:
 
 - New SoC platforms:
   - Freescale i.MX 7Solo
   - Broadcom BCM23550
   - Cirrus Logic EP7209 and EP7211 (clps711x platforms)_
   - Hisilicon HI3519
   - Renesas R8A7792
 
 Some of the other delta that is sticking out, line-count wise:
  - Exynos moves of IP blocks under an SoC bus, which causes a large delta due
    to indentation changes
  - A new Tegra K1 board: Apalis
  - A bunch of small updates to many Allwinner platforms; new hardware support,
    some cleanup, etc.

c9b95e5961 sound updates for 4.8 
Majority of this update is about ASoC, including a few new drivers,
 and the rest are mostly minor changes.  The only substantial change in
 ALSA core is about the additional error handling in the
 compress-offload API.  Below are highlights:
 
 - Add the error propagating support in compress-offload API
 
 - HD-audio: a usual Dell headset fixup, an Intel HDMI/DP fix, and the
   default mixer setup change ot turn off the loopback
 
 - Lots of updates for ASoC Intel drivers, mostly board support and bug
   fixing, and to the NAU8825 driver
 
 - Work on generalizing bits of simple-card to allow more code sharing
   with the Renesas rsrc-card (which can't use simple-card due to DPCM)
 
 - Removal of the Odroid X2 driver due to replacement with simple-card
 
 - Support for several new Mediatek platforms and associated boards
 
 - New ASoC drivers for Allwinner A10, Analog Devices ADAU7002, Broadcom
   Cygnus, Cirrus Logic CS35L33 and CS53L30, Maxim MAX8960 and MAX98504,

099c0cbd20 documentation: da9052: Update regulator bindings names to match DA9052/53 DTS expectations 
Buck and LDO binding name changes.

The binding names for the regulators have been changed to match the current
expectation from existing device tree source files.

This fix rectifies the disparity between what currently exists in some
.dts[i] board files and what is listed in this binding document. This
change re-aligns those differences and also brings the binding document
in-line with the expectations of the product datasheet from Dialog
Semiconductor.

Bucks and LDOs now follow the expected notation:
{ buck1, buck2, buck3, buck4 }
{ ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10 }

f0c98ebc57 libnvdimm for 4.8 
1/ Replace pcommit with ADR / directed-flushing:
    The pcommit instruction, which has not shipped on any product, is
    deprecated. Instead, the requirement is that platforms implement either
    ADR, or provide one or more flush addresses per nvdimm. ADR
    (Asynchronous DRAM Refresh) flushes data in posted write buffers to the
    memory controller on a power-fail event. Flush addresses are defined in
    ACPI 6.x as an NVDIMM Firmware Interface Table (NFIT) sub-structure:
    "Flush Hint Address Structure". A flush hint is an mmio address that
    when written and fenced assures that all previous posted writes
    targeting a given dimm have been flushed to media.
 
 2/ On-demand ARS (address range scrub):
    Linux uses the results of the ACPI ARS commands to track bad blocks
    in pmem devices.  When latent errors are detected we re-scrub the media
    to refresh the bad block list, userspace can also request a re-scrub at
    any time.
 
 3/ Support for the Microsoft DSM (device specific method) command format.
 
 4/ Support for EDK2/OVMF virtual disk device memory ranges.
 
 5/ Various fixes and cleanups across the subsystem.

New drivers:
 
 - New driver for Oxnas pin control and GPIO. This ARM-based chipset
   is used in a few storage (NAS) type devices.
 
 - New driver for the MAX77620/MAX20024 pin controller portions.
 
 - New driver for the Intel Merrifield pin controller.
 
 New subdrivers:
 
 - New subdriver for the Qualcomm MDM9615
 
 - New subdriver for the STM32F746 MCU
 
 - New subdriver for the Broadcom NSP SoC.
 
 Cleanups:
 
 - Demodularization of bool compiled-in drivers.
 
 Apart from this there is just regular incremental improvements to
 a lot of drivers, especially Uniphier and PFC.

a52633d8e9 mm, vmscan: move lru_lock to the node 
Node-based reclaim requires node-based LRUs and locking.  This is a
preparation patch that just moves the lru_lock to the node so later
patches are easier to review.  It is a mechanical change but note this
patch makes contention worse because the LRU lock is hotter and direct
reclaim and kswapd can contend on the same lock even when reclaiming
from different zones.

6a492b0f23 SCSI misc on 20160727 
This update includes the usual round of driver updates (fcoe, lpfc,
 ufs, qla2xxx, hisi_sas).  The most important other change is removing
 the flag to allow non-blk_mq on a per host basis (it's unused); there
 is still a global module parameter for all of SCSI just in case.  The
 rest are an assortment of minor fixes and typo updates.

7ae0ae4a02 spi: Updates for v4.8 
Quite a lot of cleanup and maintainence work going on this release in
 various drivers, and also a fix for a nasty locking issue in the core:
 
  - A fix for locking issues when external drivers explicitly locked the
    bus with spi_bus_lock() - we were using the same lock to both control
    access to the physical bus in multi-threaded I/O operations and
    exclude multiple callers.  Confusion between these two caused us to
    have scenarios where we were dropping locks.  These are fixed by
    splitting into two separate locks like should have been done
    originally, making everything much clearer and correct.
  - Support for DMA in spi_flash_read().
  - Support for instantiating spidev on ACPI systems, including some test
    devices used in Windows validation.
  - Use of the core DMA mapping functionality in the McSPI driver.
  - Start of support for ThunderX SPI controllers, involving a very big
    set of changes to the Cavium driver.
  - Support for Braswell, Exynos 5433, Kaby Lake, Merrifield, RK3036,
    RK3228, RK3368 controllers.

1cd04d293c This is the bulk of GPIO changes for the v4.8 kernel cycle. 
Core changes:
 
 - The big item is of course the completion of the character
   device ABI. It has now replaced and surpassed the former
   unmaintainable sysfs ABI: we can now hammer (bitbang)
   individual lines or sets of lines and read individual lines
   or sets of lines from userspace, and we can also register
   to listen to GPIO events from userspace. As a tie-in we
   have two new tools in tools/gpio: gpio-hammer and
   gpio-event-mon that illustrate the proper use of the new
   ABI. As someone said: the wild west days of GPIO are now
   over.
 
 - Continued to remove the pointless
   ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB Kconfig symbols.
   I'm patching hexagon, openrisc, powerpc, sh, unicore,
   ia64 and microblaze. These are either ACKed by their
   maintainers or patched anyways after a grace period and
   no response from maintainers. Some archs (ARM) come in from
   their trees, and others (x86) are still not fixed, so I
   might send a second pull request to root it out later in
   this merge window, or just defer to v4.9.
 
 - The GPIO tools are moved to the tools build system.
 
 New drivers:
 
 - New driver for the MAX77620/MAX20024.
 
 - New driver for the Intel Merrifield.
 
 - Enabled PCA953x for the TI PCA9536.
 
 - Enabled PCA953x for the Intel Edison.
 
 - Enabled R8A7792 in the RCAR driver.
 
 Driver improvements:
 
 - The STMPE and F7188x now supports the .get_direction()
   callback.
 
 - The Xilinx driver supports setting multiple lines at
   once.
 
 - ACPI support for the Vulcan GPIO controller.
 
 - The MMIO GPIO driver supports device tree probing.
 
 - The Acer One 10 is supported through the _DEP ACPI
   attribute.
 
 Cleanups:
 
 - A major cleanup of the OF/DT support code. It is way
   easier to read and understand now, probably this improves
   performance too.
 
 - Drop a few redundant .owner assignments.
 
 - Remove CLPS711x boardfile support: we are 100% DT.

Merge tag 'gpio-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.8 kernel cycle.  The big
  news is the completion of the chardev ABI which I'm very happy about
  and apart from that it's an ordinary, quite busy cycle.  The details
  are below.

  The patches are tested in linux-next for some time, patches to other
  subsystem mostly have ACKs.

  I got overly ambitious with configureing lines as input for IRQ lines
  but it turns out that some controllers have their interrupt-enable and
  input-enabling in orthogonal settings so the assumption that all IRQ
  lines are input lines does not hold.  Oh well, revert and back to the
  drawing board with that.

  Core changes:

   - The big item is of course the completion of the character device
     ABI.  It has now replaced and surpassed the former unmaintainable
     sysfs ABI: we can now hammer (bitbang) individual lines or sets of
     lines and read individual lines or sets of lines from userspace,
     and we can also register to listen to GPIO events from userspace.

     As a tie-in we have two new tools in tools/gpio: gpio-hammer and
     gpio-event-mon that illustrate the proper use of the new ABI.  As
     someone said: the wild west days of GPIO are now over.

   - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
     Kconfig symbols.  I'm patching hexagon, openrisc, powerpc, sh,
     unicore, ia64 and microblaze.  These are either ACKed by their
     maintainers or patched anyways after a grace period and no response
     from maintainers.

     Some archs (ARM) come in from their trees, and others (x86) are
     still not fixed, so I might send a second pull request to root it
     out later in this merge window, or just defer to v4.9.

   - The GPIO tools are moved to the tools build system.

  New drivers:

   - New driver for the MAX77620/MAX20024.

   - New driver for the Intel Merrifield.

   - Enabled PCA953x for the TI PCA9536.

   - Enabled PCA953x for the Intel Edison.

   - Enabled R8A7792 in the RCAR driver.

  Driver improvements:

   - The STMPE and F7188x now supports the .get_direction() callback.

   - The Xilinx driver supports setting multiple lines at once.

   - ACPI support for the Vulcan GPIO controller.

   - The MMIO GPIO driver supports device tree probing.

   - The Acer One 10 is supported through the _DEP ACPI attribute.

  Cleanups:

   - A major cleanup of the OF/DT support code.  It is way easier to
     read and understand now, probably this improves performance too.

   - Drop a few redundant .owner assignments.

   - Remove CLPS711x boardfile support: we are 100% DT"
