Pull thermal management updates from Zhang Rui:

 - Fix a problem where orderly_shutdown() is called for multiple times
   due to multiple critical overheating events raised in a short period
   by platform thermal driver. (Keerthy)

 - Introduce a backup thermal shutdown mechanism, which invokes
   kernel_power_off()/emergency_restart() directly, after
   orderly_shutdown() being issued for certain amount of time(specified
   via Kconfig). This is useful in certain conditions that userspace may
   be unable to power off the system in a clean manner and leaves the
   system in a critical state, like in the middle of driver probing
   phase. (Keerthy)

 - Introduce a new interface in thermal devfreq_cooling code so that the
   driver can provide more precise data regarding actual power to the
   thermal governor every time the power budget is calculated. (Lukasz
   Luba)

 - Introduce BCM 2835 soc thermal driver and northstar thermal driver,
   within a new sub-folder. (Rafał Miłecki)

 - Introduce DA9062/61 thermal driver. (Steve Twiss)

 - Remove non-DT booting on TI-SoC driver. Also add support to fetching
   coefficients from DT. (Keerthy)

 - Refactorf RCAR Gen3 thermal driver. (Niklas Söderlund)

 - Small fix on MTK and intel-soc-dts thermal driver. (Dawei Chien,
   Brian Bian)

b5a53b61a2 Sort of on the quieter side this time, which is probably due more 
to me not catching up as quickly on patch review than anything else.
 Overall it seems normal though, a few small changes to the core, mostly
 small non-critical fixes here and there as well as driver updates for new
 and existing hardware support. The biggest things are the TI clk driver
 rework to lay the groundwork for clkctrl support in the next merge window
 and the AmLogic audio/graphics clk support.
 
 Core:
  * clk_possible_parents debugfs file so we know which parents a clk
    could possibly have
  * Fix to make clk rate change notifiers stop on the first failure instead
    of continuing
 
 New Drivers:
  * Mediatek MT6797 SoCs
  * hi655x PMIC clks
  * AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
  * Allwinner H5 SoCs and PRCM hardware
 
 Updates:
  * Nvidia Tegra T210 cleanups and non-critical fixes
  * TI OMAP cleanups in preparation for clkctrl support
  * Trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
  * ZTE zx296718 SoC VGA clks
  * Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
  * Support for IDT VersaClock 5P49V5935
  * Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3 support

a2d9214c73 TEE driver infrastructure and OP-TEE drivers 
This branch introduces a generic TEE framework in the kernel, to handle
 trusted environemtns (security coprocessor or software implementations
 such as OP-TEE/TrustZone). I'm sending it separately from the other
 arm-soc driver changes to give it a little more visibility, once
 the subsystem is merged, we will likely keep this in the arm₋soc
 drivers branch or have the maintainers submit pull requests directly,
 depending on the patch volume.
 
 I have reviewed earlier versions in the past, and have reviewed
 the latest version in person during Linaro Connect BUD17.
 
 Here is my overall assessment of the subsystem:
 
 * There is clearly demand for this, both for the generic
   infrastructure and the specific OP-TEE implementation.
 
 * The code has gone through a large number of reviews,
   and the review comments have all been addressed, but
   the reviews were not coming up with serious issues any more
   and nobody volunteered to vouch for the quality.
 
 * The user space ioctl interface is sufficient to work with the
   OP-TEE driver, and it should in principle work with other
   TEE implementations that follow the GlobalPlatform[1] standards,
   but it might need to be extended in minor ways depending on
   specific requirements of future TEE implementations
 
 * The main downside of the API to me is how the user space
   is tied to the TEE implementation in hardware or firmware,
   but uses a generic way to communicate with it. This seems
   to be an inherent problem with what it is trying to do,
   and I could not come up with any better solution than what
   is implemented here.

85d604902e ARM: Device-tree updates 
Device-tree continues to see lots of updates. The majority of patches
 here are smaller changes for new hardware on existing platforms, and
 there are a few larger changes worth pointing out.
 
 Major new platforms:
 
  - Gemini has been ported to DT, so a handful of "new" platforms moved over
    from board files
  - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288 SoM and RDK
  - A bunch of embedded platforms, several Linksys platforms, Synology DS116,
  - Motorola Droid4 (really old OMAP-based phone) support is added.
 
 Some refactorings, i.e. Allwinner H3/H5 support is commonalized.
 
 And lots of smaller changes, cleanups, etc. See shortlog for more description
 
 We're adding ability to cross-include DT files between arm and arm64,
 by creating appropriate links in the dt-include directory, and using arm/
 and arm64/ as include prefixes. This will avoid other local hacks such as
 per-file links between the two arch trees (this broke for external mirroring
 of DT contents). Now they can just provide their own appropriate dt-include
 hierarcy per platform.

5a61ef74f2 powerpc/64s: Support new device tree binding for discovering CPU features 
The ibm,powerpc-cpu-features device tree binding describes CPU features with
ASCII names and extensible compatibility, privilege, and enablement metadata
that allows improved flexibility and compatibility with new hardware.

The interface is described in detail in ibm,powerpc-cpu-features.txt in this
patch.

Currently this code is not enabled by default, and there are no released
firmwares that provide the binding.

Pull ARM updates from Russell King:
 "Lots of little things this time:

   - allow modules to be autoloaded according to the HWCAP feature bits
     (used primarily for crypto modules)

   - split module core and init PLT sections, since the core code and
     init code could be placed far apart, and the PLT sections need to
     be local to the code block.

   - three patches from Chris Brandt to allow Cortex-A9 L2 cache
     optimisations to be disabled where a SoC didn't wire up the out of
     band signals.

   - NoMMU compliance fixes, avoiding corruption of vector table which
     is not being used at this point, and avoiding possible register
     state corruption when switching mode.

   - fixmap memory attribute compliance update.

   - remove unnecessary locking from update_sections_early()

   - ftrace fix for DEBUG_RODATA with !FRAME_POINTER"

c6a677c6f3 Staging/IIO patches for 4.12-rc1 
Here is the big staging tree update for 4.12-rc1.  And it's a big one,
 adding about 350k new lines of crap^Wcode, mostly all in a big dump of
 media drivers from Intel.  But there's other new drivers in here as
 well, yet-another-wifi driver, new IIO drivers, and a new crypto
 accelerator.  We also deleted a bunch of stuff, mostly in patch
 cleanups, but also the Android ION code has shrunk a lot, and the
 Android low memory killer driver was finally deleted, much to the
 celebration of the -mm developers.
 
 All of these have been in linux-next with a few build issues that will
 show up when you merge to your tree, I'll follow up with fixes for those
 after this gets merged.

644b4930bf drm/tegra: Changes for v4.12-rc1 
This contains various fixes to the host1x driver as well as a plug for a
 leak of kernel pointers to userspace.
 
 A fairly big addition this time around is the Video Image Composer (VIC)
 support that can be used to accelerate some 2D and image compositing
 operations.
 
 Furthermore the driver now supports FB modifiers, so we no longer rely
 on a custom IOCTL to set those.
 
 Finally this contains a few preparatory patches for Tegra186 support
 which unfortunately didn't quite make it this time, but will hopefully
 be ready for v4.13.

8f28472a73 USB patches for 4.12-rc1 
Here is the big USB patchset for 4.12-rc1.
 
 Lots of good stuff here, after many many many attempts, the kernel
 finally has a working typeC interface, many thanks to the Heikki and
 Guenter and others who have taken the time to get this merged.  It
 wasn't an easy path for them at all.
 
 There's also a staging driver that uses this new api, which is why it's
 coming in through this tree.
 
 Along with that, there's the usual huge number of changes for gadget
 drivers, xhci, and other stuff.  Johan also finally refactored pretty
 much every driver that was looking at USB endpoints to do it in a common
 way, which will help prevent any "badly-formed" devices from causing
 problems in drivers.  That too wasn't a simple task.
 
 All of these have been in linux-next for a while with no reported
 issues.

2bd8040174 This is the bulk of GPIO changes for the v4.12 kernel cycle: 
Core changes
 
 - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
   This was a much discussed change. It affects use cases where people
   write drivers that might or might not be using GPIO resources.
   I have decided that this is the lesser evil right now.
 
 - Make gpiod_count() behave consistently across different hardware
   descriptions.
 
 - Fix the syntax around open drain/open source to not infer active
   high/low semantics.
 
 New drivers
 
 - A new single-register fixed-direction framework driver for hardware
   that have lines controlled by a single register that just work in
   one direction (out or in), including IRQ support.
 
 - Support the Fintek F71889A GPIO SuperIO controller.
 
 - Support the National NI 169445 MMIO GPIO.
 
 - Support for the X-Gene derivative of the DWC GPIO controller
 
 - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
 
 - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
   and replace both the Gemini and the Moxa ART custom drivers with
   this driver.
 
 Driver improvements
 
 - A whole slew of drivers have their spinlocks chaned to raw spinlocks
   as they provide irqchips, and thus we are progressing on realtime
   compliance.
 
 - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
   resources.
 
 - Support for the embedded PWM controller inside the MVEBU driver.
 
 - Debounce, open source and open drain support for the Aspeed driver.
 
 - Misc smaller fixes like spelling and syntax and whatnot.

d25e436c4b spi: Updates for v4.12 
There's quite a lot of small driver specific fixes and enhancements in
 this release but the main activity has been around the loopback and
 spidev test drivers which is good to see as it should hopefully help
 improve the quality of all the drivers as people start to make use of
 the new code:
 
  - Additional tests in the loopback test driver for vmalloc()
    compatibility and around delays together with fixes for existing
    tests.
  - Support for testing continuous data transfer for use in soak testing.
  - Device property support for board info platforms.
  - Support for registering empty sets of devices via board info (useful
    when writing code to enumerate hardware automatically).

726bd22310 powerpc/8xx: Adding support of IRQ in MPC8xx GPIO 
This patch allows the use of IRQ to notify the change of GPIO status
on MPC8xx CPM IO ports. This then allows to associate IRQs to GPIOs
in the Device Tree.

Ex:
	CPM1_PIO_C: gpio-controller@960 {
		#gpio-cells = <2>;
		compatible = "fsl,cpm1-pario-bank-c";
		reg = <0x960 0x10>;
		fsl,cpm1-gpio-irq-mask = <0x0fff>;
		interrupts = <1 2 6 9 10 11 14 15 23 24 26 31>;
		interrupt-parent = <&CPM_PIC>;
		gpio-controller;
	};

The property 'fsl,cpm1-gpio-irq-mask' defines which of the 16 GPIOs
have the associated interrupts defined in the 'interrupts' property.

Pull HID subsystem updates from Jiri Kosina:

 - The need for HID_QUIRK_NO_INIT_REPORTS per-device quirk has been
   growing dramatically during past years, so the time has come to
   switch over the default, and perform the pro-active reading only in
   cases where it's really needed (multitouch, wacom).

   The only place where this behavior is (in some form) preserved is
   hiddev so that we don't introduce userspace-visible change of
   behavior.

   From Benjamin Tissoires

 - HID++ support for power_supply / baterry reporting.

   From Benjamin Tissoires and Bastien Nocera

 - Vast improvements / rework of DS3 and DS4 in Sony driver.

   From Roderick Colenbrander

 - Improvment (in terms of getting closer to the Microsoft's
   interpretation of slightly ambiguous specification) of logical range
   interpretation in case null-state is set in the rdesc.

   From Valtteri Heikkilä and Tomasz Kramkowski

 - A lot of newly supported device IDs and small assorted fixes

68fed41e0f This is the bulk of pin control changes for the v4.12 cycle: 
Core changes:
 
 - Add bi-directional and output-enable pin configurations to
   the generic bindings and generic pin controlling core.
 
 New drivers or subdrivers:
 
 - Armada 37xx SoC pin controller and GPIO support.
 
 - Axis ARTPEC-6 SoC pin controller support.
 
 - AllWinner A64 R_PIO controller support, and opening up the
   AllWinner sunxi driver for ARM64 use.
 
 - Rockchip RK3328 support.
 
 - Renesas R-Car H3 ES2.0 support.
 
 - STM32F469 support in the STM32 driver.
 
 - Aspeed G4 and G5 pin controller support.
 
 Improvements:
 
 - A whole slew of realtime improvements to drivers implementing
   irqchips: BCM, AMD, SiRF, sunxi, rockchip.
 
 - Switch meson driver to get the GPIO ranges from the device
   tree.
 
 - Input schmitt trigger support on the Rockchip driver.
 
 - Enable the sunxi (AllWinner) driver to also be used on ARM64
   silicon.
 
 - Name the Qualcomm QDF2xxx GPIO lines.
 
 - Support GMMR GPIO regions on the Intel Cherryview. This
   fixes a serialization problem on these platforms.
 
 - Pad retention support for the Samsung Exynos 5433.
 
 - Handle suspend-to-ram in the AT91-pio4 driver.
 
 - Pin configuration support in the Aspeed driver.
 
 Cleanups:
 
 - The final name of Rockchip RK1108 was RV1108 so rename the
   driver and variables to stay consistent.

Merge tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.12 cycle.

  The extra week before the merge window actually resulted in some of
  the type of fixes that usually arrive after the merge window already
  starting to trickle in from eager developers using -next, I'm
  impressed.

  I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
  with the onset of Samsung patches. It works great.

  Apart from that it is a boring round, just incremental updates and
  fixes all over the place, no serious core changes or anything exciting
  like that. The most pleasing to see is Julia Cartwrights work to audit
  the irqchip-providing drivers for realtime locking compliance. It's
  one of those "I should really get around to looking into that" things
  that have been on my TODO list since forever.

  Summary:

  Core changes:

   - add bi-directional and output-enable pin configurations to the
     generic bindings and generic pin controlling core.

  New drivers or subdrivers:

   - Armada 37xx SoC pin controller and GPIO support.

   - Axis ARTPEC-6 SoC pin controller support.

   - AllWinner A64 R_PIO controller support, and opening up the
     AllWinner sunxi driver for ARM64 use.

   - Rockchip RK3328 support.

   - Renesas R-Car H3 ES2.0 support.

   - STM32F469 support in the STM32 driver.

   - Aspeed G4 and G5 pin controller support.

  Improvements:

   - a whole slew of realtime improvements to drivers implementing
     irqchips: BCM, AMD, SiRF, sunxi, rockchip.

   - switch meson driver to get the GPIO ranges from the device tree.

   - input schmitt trigger support on the Rockchip driver.

   - enable the sunxi (AllWinner) driver to also be used on ARM64
     silicon.

   - name the Qualcomm QDF2xxx GPIO lines.

   - support GMMR GPIO regions on the Intel Cherryview. This fixes a
     serialization problem on these platforms.

   - pad retention support for the Samsung Exynos 5433.

   - handle suspend-to-ram in the AT91-pio4 driver.

   - pin configuration support in the Aspeed driver.

  Cleanups:

   - the final name of Rockchip RK1108 was RV1108 so rename the driver

 "Here are some highlights from the 2065 networking commits that
  happened this development cycle:

   1) XDP support for IXGBE (John Fastabend) and thunderx (Sunil Kowuri)

   2) Add a generic XDP driver, so that anyone can test XDP even if they
      lack a networking device whose driver has explicit XDP support
      (me).

   3) Sparc64 now has an eBPF JIT too (me)

   4) Add a BPF program testing framework via BPF_PROG_TEST_RUN (Alexei
      Starovoitov)

   5) Make netfitler network namespace teardown less expensive (Florian
      Westphal)

   6) Add symmetric hashing support to nft_hash (Laura Garcia Liebana)

   7) Implement NAPI and GRO in netvsc driver (Stephen Hemminger)

   8) Support TC flower offload statistics in mlxsw (Arkadi Sharshevsky)

   9) Multiqueue support in stmmac driver (Joao Pinto)

  10) Remove TCP timewait recycling, it never really could possibly work
      well in the real world and timestamp randomization really zaps any
      hint of usability this feature had (Soheil Hassas Yeganeh)

  11) Support level3 vs level4 ECMP route hashing in ipv4 (Nikolay
      Aleksandrov)

  12) Add socket busy poll support to epoll (Sridhar Samudrala)

  13) Netlink extended ACK support (Johannes Berg, Pablo Neira Ayuso,
      and several others)

  14) IPSEC hw offload infrastructure (Steffen Klassert)"
