8522240385 Documentation: fsl-mc: binding updates for MSIs, ranges, PHYs 
-The Freescale Management Complex and all associated objects
 use message interrupts, and thus an msi-parent is required.

-Define a ranges property to specify the mapping between
 the MC address space and the system address space.

-The fsl-mc node may optionally have dpmac sub-nodes that describe
 the relationship between the Ethernet MACs which belong to the MC
 and the Ethernet PHYs on the system board.

895a1067d5 SCSI misc on 20160326 
The only new stuff which missed the first pull request is an update to
 the UFS driver.  The rest is an assortment of bug fixes and minor
 tweaks which appeared recently (some are fixes for recent code and
 some are stuff spotted recently by the checkers or the new gcc-6
 compiler [most of Arnd's stuff]).

 "The second batch of power management and ACPI updates for v4.6.

  Included are fixups on top of the previous PM/ACPI pull request and
  other material that didn't make into it but still should go into 4.6.

  Among other things, there's a fix for an intel_pstate driver issue
  uncovered by recent cpufreq changes, a workaround for a boot hang on
  Skylake-H related to the handling of deep C-states by the platform and
  a PCI/ACPI fix for the handling of IO port resources on non-x86
  architectures plus some new device IDs and similar.

Here are some final updates for ARM SoC specific dts files:
 
 * The i.MX changes were sent relatively late, and had a dependency
   on the clk tree, so I delayed that a bit. Support for the new
   i.MX6qp SoC and a couple of new boards is added in this branch.
 
 * Uniphier renames a few files to match the final product names
   that were decided by the company, kudos to the kernel developer(s)
   for getting support upstream before the product release.
   Also two boards are added. The patches were posted early enough
   and nice overall, but we forgot to apply them and decided to
   give it some more time in linux-next

Pull thermal updates from Zhang Rui:

 - Fix a regression where bogus trip points on some Lenovo laptops start
   to screw up thermal control after commit 81ad4276b5 ("Thermal:
   initialize thermal zone device correctly").

   On these Lenovo laptops, a bogus passive trip point is reported,
   which is 0 degree Celsius.  Without commit 81ad4276b5, thermal zone
   fails to set cooling devices to proper cooling state, which is a bug.
   But with commit 81ad4276b5 applied, the processors are always
   throttled on these Lenovo laptops because the current temperature is
   always higher than the passive trip point.

   Fix things to ignore such bogus trip points.  (Zhang Rui)

 - Introduce Mediatek thermal driver.  (Sascha Hauer)

 - Introduce devm_ versions of OF thermal sensor register API.  (Laxman
   Dewangan)

 - Changes in Kconfigs to allow compile test on UM arch.  (Krzysztof
   Kozlowski)

 - Introduce Skylake support in intel_pch_thermal driver.  (Srinivas
   Pandruvada)

 - Several small fixes on Rockchip, TI-SoC, Tegra, RCar, and Exynos
   thermal drivers.

33c1f638a0 The clk changes for this release cycle are mostly dominated by 
new device support in terms of LoC, but there has been some cleanup
 in the core as well as the usual minor clk additions to various
 drivers.
 
 Core:
 
  - parent tracking has been simplified
 
  - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
 
  - of_clk_init() doesn't consider disabled DT nodes anymore
 
  - clk_unregister() had an error path bug squashed
 
  - of_clk_get_parent_count() has been fixed to only return unsigned ints
 
  - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
 
 New Drivers:
 
  - NXP LPC18xx creg
 
  - QCOM IPQ4019 GCC
 
  - TI dm814x ADPLL
 
  - i.MX6QP
 
 Updates:
 
  - Cyngus audio clks found on Broadcom iProc devices
 
  - Non-critical fixes for BCM2385 PLLs
 
  - Samsung exynos5433 updates for clk id errors, HDMI support,
    suspend/resume simplifications
 
  - USB, CAN, LVDS, and FCP clks on shmobile devices
 
  - sunxi got support for more clks on new SoCs and went through a minor
    refactoring/rewrite to use a simpler factor clk construct
 
  - rockchip added some more clk ids and added suport for fraction dividers
 
  - QCOM GDSCs in msm8996
 
  - A new devm helper to make adding custom actions simpler (acked by Greg)

  The octeon changes were applied pretty recently before the merge
  window.  I am aware.  They are the first (and relatively simple)
  patches of a larger overhaul to this driver.  In case something goes
  wrong with them, they are easy to fix (or revert).  The advantage I
  see is that they are out of the way, and I can concentrate on the next
  block of patches.  I really would like to apply the overhaul in
  smaller batches to avoid regressions.  And waiting a cycle for the
  introductory patches seemed too much of a delay for me"

- Fix ABI regression of MMC BLK ioctl
  - Remove the unused MMC_DATA_STREAM flag
  - Enable asynchronous system PM for the host device
  - Minor fixes and clean-ups
 
 SDHCI host:
 Throughout the years, the numbers of SDHCI variants have increased and so
 has also the numbers of SDHCI callbacks/quirks. The purpose of these
 callbacks/quirks were to enable SDHCI to deal with variant specific
 requirements, but unfortunate this method didn't scale. Instead we have
 ended up with a mess. Not only did the code become suboptimal but also
 highly fragile.
 
 Lately many discussions of how to move forward with SDHCI has taken place
 at the MMC mailing list. Step by step, we aim to turn SDHCI's common code
 into a set of library functions. This will enable for optimizations and
 allow some of the existing callbacks/quirks to be removed, which also
 should help to make the code less fragile.
 
 Therefore I am also really pleased to announce that Adrian Hunter (Intel)
 has volunteered to step in as the maintainer for SDHCI.
 
 Future wise, I hope the community around SDHCI will continue to grow and
 that this release cycle can be the starting point of moving SDHCI into a
 better shape. As a matter of fact, already in this cycle the re-factoring
 has begun, but of course there are also fixes and new features included.

Pull arm[64] perf updates from Will Deacon:
 "I have another mixed bag of ARM-related perf patches here.

  It's about 25% CPU and 75% interconnect, but with drivers/bus/
  languishing without an obvious maintainer or tree, Olof and I agreed
  to keep all of these PMU patches together.  I suspect a whole load of
  code from drivers/bus/arm-* can be moved under drivers/perf/, so
  that's on the radar for the future.

  Summary:

   - Initial support for ARMv8.1 CPU PMUs

   - Support for the CPU PMU in Cavium ThunderX

   - CPU PMU support for systems running 32-bit Linux in secure mode

94b5293d55 Documentation: dt: mailbox: Add TI Message Manager 
Message Manager is a hardware block used to communicate with various
processor systems within certain Texas Instrument's Keystone
generation SoCs.

This hardware engine is used to transfer messages from various compute
entities(or processors) within the SoC. It is designed to be self
contained without needing software initialization for operation.

d0e286415d irqchip/mbigen: Adjust DT bindings to handle multiple devices in a module 
A mbigen hardware module can contain more than one device node. These device
nodes contain the same register definition.

mbigen_dev1:intc_dev1 {
	...
	reg = <0x0 0xc0080000 0x0 0x10000>;
	...
};

mbigen_dev2:intc_dev2 {
	...
	reg = <0x0 0xc0080000 0x0 0x10000>;
	...
};

In this case both devices try to request the same resource resulting in a
resource conflict.

To address this problem the devices need to be subnodes of the mbigen hardware
module, which then contains the unique register space.

46e595a17d ARM: SoC driver updates for v4.6 
Driver updates for ARM SoCs, these contain various things that touch
 the drivers/ directory but got merged through arm-soc for practical
 reasons:
 
 - Rockchip rk3368 gains power domain support
 - Small updates for the ARM spmi driver
 - The Atmel PMC driver saw a larger rework, touching both
   arch/arm/mach-at91 and drivers/clk/at91
 - All reset controller driver changes alway get merged through
   arm-soc, though this time the largest change is the addition
   of a MIPS pistachio reset driver
 - One bugfix for the NXP (formerly Freescale) i.MX weim bus driver

Pull networking updates from David Miller:
 "Highlights:

   1) Support more Realtek wireless chips, from Jes Sorenson.

   2) New BPF types for per-cpu hash and arrap maps, from Alexei
      Starovoitov.

   3) Make several TCP sysctls per-namespace, from Nikolay Borisov.

   4) Allow the use of SO_REUSEPORT in order to do per-thread processing
   of incoming TCP/UDP connections.  The muxing can be done using a
   BPF program which hashes the incoming packet.  From Craig Gallek.

   5) Add a multiplexer for TCP streams, to provide a messaged based
      interface.  BPF programs can be used to determine the message
      boundaries.  From Tom Herbert.

   6) Add 802.1AE MACSEC support, from Sabrina Dubroca.

   7) Avoid factorial complexity when taking down an inetdev interface
      with lots of configured addresses.  We were doing things like
      traversing the entire address less for each address removed, and
      flushing the entire netfilter conntrack table for every address as
      well.

   8) Add and use SKB bulk free infrastructure, from Jesper Brouer.

   9) Allow offloading u32 classifiers to hardware, and implement for
      ixgbe, from John Fastabend.

  10) Allow configuring IRQ coalescing parameters on a per-queue basis,
      from Kan Liang.

  11) Extend ethtool so that larger link mode masks can be supported.
      From David Decotigny.

  12) Introduce devlink, which can be used to configure port link types
      (ethernet vs Infiniband, etc.), port splitting, and switch device
      level attributes as a whole.  From Jiri Pirko.

  13) Hardware offload support for flower classifiers, from Amir Vadai.

  14) Add "Local Checksum Offload".  Basically, for a tunneled packet
      the checksum of the outer header is 'constant' (because with the
      checksum field filled into the inner protocol header, the payload
      of the outer frame checksums to 'zero'), and we can take advantage
      of that in various ways.  From Edward Cree"

Linus Torvalds
1a46712aa9 This is the bulk of GPIO changes for kernel v4.6: 
Core changes:
 
 - The gpio_chip is now a *real device*. Until now the gpio chips
   were just piggybacking the parent device or (gasp) floating in
   space outside of the device model. We now finally make GPIO chips
   devices. The gpio_chip will create a gpio_device which contains
   a struct device, and this gpio_device struct is kept private.
   Anything that needs to be kept private from the rest of the kernel
   will gradually be moved over to the gpio_device.
 
 - As a result of making the gpio_device a real device, we have added
   resource management, so devm_gpiochip_add_data() will cut down on
   overhead and reduce code lines. A huge slew of patches convert
   almost all drivers in the subsystem to use this.
 
 - Building on making the GPIO a real device, we add the first step
   of a new userspace ABI: the GPIO character device. We take small
   steps here, so we first add a pure *information* ABI and the tool
   "lsgpio" that will list all GPIO devices on the system and all
   lines on these devices. We can now discover GPIOs properly from
   userspace. We still have not come up with a way to actually *use*
   GPIOs from userspace.
 
 - To encourage people to use the character device for the future,
   we have it always-enabled when using GPIO. The old sysfs ABI is
   still opt-in (and can be used in parallel), but is marked as
   deprecated. We will keep it around for the foreseeable future,
   but it will not be extended to cover ever more use cases.
 
 Cleanup:
 
 - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
   includes. This dates back to when GPIO was an opt-in feature and
   no shared library even existed: just a header file with proper
   prototypes was provided and all semantics were up to the arch to
   implement. These patches make the GPIO chip even more a proper
   device and cleans out leftovers of the old in-kernel API here
   and there. Still some cruft is left but it's very little now.
 
 - There is still some clamping of return values for .get() going
   on, but we now return sane values in the vast majority of drivers
   and the errorpath is sanitized. Some patches for powerpc, blackfin
   and unicore still drop in.
 
 - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
   implementations to use gpiochip_add_data() and cut down on code
   lines.
 
 - MPC8xxx is converted to use the generic GPIO helpers.
 
 - ATH79 is converted to use the generic GPIO helpers.
 
 New drivers:
 
 - WinSystems WS16C48
 
 - Acces 104-DIO-48E
 
 - F81866 (a F7188x variant)
 
 - Qoric (a MPC8xxx variant)

Merge tag 'gpio-v4.6-1' 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 kernel v4.6.  There is quite a
  lot of interesting stuff going on.

  The patches to other subsystems and arch-wide are ACKed as far as
  possible, though I consider things like per-arch <asm/gpio.h> as
  essentially a part of the GPIO subsystem so it should not be needed.

  Core changes:

   - The gpio_chip is now a *real device*.  Until now the gpio chips
     were just piggybacking the parent device or (gasp) floating in
     space outside of the device model.

     We now finally make GPIO chips devices.  The gpio_chip will create
     a gpio_device which contains a struct device, and this gpio_device
     struct is kept private.  Anything that needs to be kept private
     from the rest of the kernel will gradually be moved over to the
     gpio_device.

   - As a result of making the gpio_device a real device, we have added
     resource management, so devm_gpiochip_add_data() will cut down on
     overhead and reduce code lines.  A huge slew of patches convert
     almost all drivers in the subsystem to use this.

   - Building on making the GPIO a real device, we add the first step of
     a new userspace ABI: the GPIO character device.  We take small
     steps here, so we first add a pure *information* ABI and the tool
     "lsgpio" that will list all GPIO devices on the system and all
     lines on these devices.

     We can now discover GPIOs properly from userspace.  We still have
     not come up with a way to actually *use* GPIOs from userspace.

   - To encourage people to use the character device for the future, we
     have it always-enabled when using GPIO.  The old sysfs ABI is still
     opt-in (and can be used in parallel), but is marked as deprecated.

     We will keep it around for the foreseeable future, but it will not
     be extended to cover ever more use cases.

  Cleanup:

   - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
     includes.

     This dates back to when GPIO was an opt-in feature and no shared
     library even existed: just a header file with proper prototypes was
     provided and all semantics were up to the arch to implement.  These
     patches make the GPIO chip even more a proper device and cleans out
     leftovers of the old in-kernel API here and there.

     Still some cruft is left but it's very little now.

   - There is still some clamping of return values for .get() going on,
     but we now return sane values in the vast majority of drivers and
     the errorpath is sanitized.  Some patches for powerpc, blackfin and
     unicore still drop in.

   - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
     implementations to use gpiochip_add_data() and cut down on code
     lines.

   - MPC8xxx is converted to use the generic GPIO helpers.

   - ATH79 is converted to use the generic GPIO helpers.

  New drivers:

   - WinSystems WS16C48

   - Acces 104-DIO-48E

   - F81866 (a F7188x variant)

   - Qoric (a MPC8xxx variant)

   - TS-4800

   - SPI serializers (pisosr): simple 74xx shift registers connected to
     SPI to obtain a dirt-cheap output-only GPIO expander.

   - Texas Instruments TPIC2810

   - Texas Instruments TPS65218

   - Texas Instruments TPS65912

7480e0aabd sh: add device tree support and generic board using device tree 
Add a new pseudo-board, within the existing SH boards/machine-vectors
framework, which does not represent any actual hardware but instead
requires all hardware to be described by the device tree blob provided
by the boot loader. Changes made are thus non-invasive and do not risk
breaking support for legacy boards.

New hardware, including the open-hardware J2 and associated SoC
devices, will use device free from the outset. Legacy SH boards can
transition to device tree once all their hardware has device tree
bindings, driver support for device tree, and a dts file for the
board.

It is intented that, once all boards are supported in the new
framework, the existing machine-vectors framework should be removed
and the new device tree setup code integrated directly.

Merge tag 'dmaengine-4.6-rc1' of git://git.infradead.org/users/vkoul/slave-dma

Pull dmaengine updates from Vinod Koul:
 "This is smallish update with minor changes to core and new driver and
  usual updates.  Nothing super exciting here..

   - We have made slave address as physical to enable driver to do the
     mapping.

   - We now expose the maxburst for slave dma as new capability so
     clients can know this and program accordingly

   - addition of device synchronize callbacks on omap and edma.

   - pl330 updates to support DMAFLUSHP for Rockchip platforms.

   - Updates and improved sg handling in Xilinx VDMA driver.

   - New hidma qualcomm dma driver, though some bits are still in
     progress"
