Linus Torvalds 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.

  move the general case towards more sane behavior.

  There are also miscellaneous fixes, including fixes to handling

Nicolas Dichtel 61562f981e uapi: export all arch specifics directories
This patch removes the need of subdir-y. Now all files/directories under
arch/<arch>/include/uapi/ are exported.

The only change for userland is the layout of the command 'make
headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
Those new directories contains all files/directories of the specified arch.

Note that only cris and tile have more directories than only asm:
 - arch-v[10|32] for cris;
 - arch for tile.

Nicolas Dichtel fcc8487d47 uapi: export all headers under uapi directories
Regularly, when a new header is created in include/uapi/, the developer
forgets to add it in the corresponding Kbuild file. This error is usually
detected after the release is out.

In fact, all headers under uapi directories should be exported, thus it's
useless to have an exhaustive list.

After this patch, the following files, which were not exported, are now
exported (with make headers_install_all):

Paolo Valente 43c1b3d6e5 block, bfq: stress that low_latency must be off to get max throughput
The introduction of the BFQ and Kyber I/O schedulers has triggered a
new wave of I/O benchmarks. Unfortunately, comments and discussions on
these benchmarks confirm that there is still little awareness that it
is very hard to achieve, at the same time, a low latency and a high
throughput. In particular, virtually all benchmarks measure
throughput, or throughput-related figures of merit, but, for BFQ, they
use the scheduler in its default configuration. This configuration is
geared, instead, toward a low latency. This is evidently a sign that
BFQ documentation is still too unclear on this important aspect. This
commit addresses this issue by stressing how BFQ configuration must be
(easily) changed if the only goal is maximum throughput.

Linus Torvalds 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.

 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.

Pull ARM Device-tree updates from Olof Johansson:
 "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.

Kristina Martsenko f0e421b1bf arm64: documentation: document tagged pointer stack constraints
Some kernel features don't currently work if a task puts a non-zero
address tag in its stack pointer, frame pointer, or frame record entries
(FP, LR).

For example, with a tagged stack pointer, the kernel can't deliver
signals to the process, and the task is killed instead. As another
example, with a tagged frame pointer or frame records, perf fails to
generate call graphs or resolve symbols.

For now, just document these limitations, instead of finding and fixing
everything that doesn't work, as it's not known if anyone needs to use
tags in these places anyway.

In addition, as requested by Dave Martin, generalize the limitations
into a general kernel address tag policy, and refactor
tagged-pointers.txt to include it.

Fixes: d50240a5f6 ("arm64: mm: permit use of tagged pointers at EL0")

Nicholas Piggin 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.

Relax the requirement of the order that the collection entries are

Between these two commits, commit d9414774dc ("cifs: Convert cifs to
new aops.") added a check in cifs_write_begin(), but that check was soon
removed by commit a98ee8c1c7 ("[CIFS] fix regression in
cifs_write_begin/cifs_write_end").

Therefore, AOP_FLAG_UNINTERRUPTIBLE flag is checked nowhere.  Let's
remove this flag.  This patch has no functionality changes.

As we are reusing crashkernel parameter instead of fadump_reserve_mem
parameter to specify the memory to reserve for fadump's crash kernel,

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()

Masahiro Yamada 37d69ee308 docs: bump minimal GNU Make version to 3.81
Since 2014, you can't successfully build kernels with GNU Make version
3.80. Example errors:

  $ git describe
  v4.11
  $ make --version | head -1
  GNU Make 3.80
  $ make defconfig
    HOSTCC  scripts/basic/fixdep
  scripts/Makefile.host:135: *** missing separator.  Stop.
  make: *** [defconfig] Error 2
  $ make ARCH=arm64 help
  arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'.  Stop.
  $ make help >/dev/null
  ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive
  ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional.  Stop.
  make: *** [help] Error 2

The first breakage was introduced by commit c8589d1e9e ("kbuild:
handle multi-objs dependency appropriately").  Since then (i.e. v3.18),
GNU Make 3.80 has not been able to compile the kernel, but nobody has
ever complained aboutt (or noticed) it.

Even GNU Make 3.81 is more than 10 years old.  It would not hurt to
match the documentation with reality instead of fixing makefiles.

Linus Torvalds 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.

Linus Torvalds 7246f60068 powerpc updates for 4.12 part 1.
Highlights include:
 
  - Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
    virtual address space, but a process can request access to the full 512TB by
    passing a hint to mmap().
 
  - Support for the new Power9 "XIVE" interrupt controller.
 
  - TLB flushing optimisations for the radix MMU on Power9.
 
  - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
    Architecture 2.0".
 
  - The ability to configure the mmap randomisation limits at build and runtime.
 
  - Several small fixes and cleanups to the kprobes code, as well as support for
    KPROBES_ON_FTRACE.
 
  - Major improvements to handling of system reset interrupts, correctly treating
    them as NMIs, giving them a dedicated stack and using a new hypervisor call
    to trigger them, all of which should aid debugging and robustness.
 
 Many fixes and other minor enhancements.

Keerthy ef1d87e06a thermal: core: Add a back up thermal shutdown mechanism
orderly_poweroff is triggered when a graceful shutdown
of system is desired. This may be used in many critical states of the
kernel such as when subsystems detects conditions such as critical
temperature conditions. However, in certain conditions in system
boot up sequences like those in the middle of driver probes being
initiated, userspace will be unable to power off the system in a clean
manner and leaves the system in a critical state. In cases like these,
the /sbin/poweroff will return success (having forked off to attempt
powering off the system. However, the system overall will fail to
completely poweroff (since other modules will be probed) and the system
is still functional with no userspace (since that would have shut itself
off).

However, there is no clean way of detecting such failure of userspace
powering off the system. In such scenarios, it is necessary for a backup
workqueue to be able to force a shutdown of the system when orderly
shutdown is not successful after a configurable time period.

freedesktop.org has adopted a formal&enforced code of conduct:

https://www.fooishbar.org/blog/fdo-contributor-covenant/
https://www.freedesktop.org/wiki/CodeOfConduct/

Besides formalizing things a bit more I don't think this changes
anything for us, we've already peer-enforced respectful and
constructive interactions since a long time. But it's good to document
things properly.

v2: Drop confusing note from commit message and clarify the grammer
(Chris, Alex and others).

Dave Airlie 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.

Linus Torvalds 0be75179df Driver core patches for 4.12-rc1
Very tiny pull request for 4.12-rc1 for the driver core this time
 around.
 
 There are some documentation fixes, an eventpoll.h fixup to make it
 easier for the libc developers to take our header files directly, and
 some very minor driver core fixes and changes.
 
 All have been in linux-next for a very long time with no reported
 issues.

Linus Torvalds 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.

Linus Torvalds 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.

Linus Torvalds 4c174688ee New features for this release:
o Pretty much a full rewrite of the processing of function plugins.
    i.e. echo do_IRQ:stacktrace > set_ftrace_filter
 
  o The rewrite was needed to add plugins to be unique to tracing instances.
    i.e. mkdir instance/foo; cd instances/foo; echo do_IRQ:stacktrace > set_ftrace_filter
    The old way was written very hacky. This removes a lot of those hacks.
 
  o New "function-fork" tracing option. When set, pids in the set_ftrace_pid
    will have their children added when the processes with their pids
    listed in the set_ftrace_pid file forks.
 
  o Exposure of "maxactive" for kretprobe in kprobe_events
 
  o Allow for builtin init functions to be traced by the function tracer
    (via the kernel command line). Module init function tracing will come
    in the next release.
 
  o Added more selftests, and have selftests also test in an instance.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma

Pull rdma updates from Doug Ledford:
 "More exchaustive description of primary updates in this release:

   - Lots of driver fixes and misc fixes across the board.

   - I had to base on a net-next tree because the IPoIB Accelorator
     patches needed it.

     Unfortunately, it was known to Mellanox that there would need to be
     an IPoIB accelorator patch to the net tree (which left some
     functions turned off by an #ifdef construct to avoid warnings about
     defined but unused functions), then one to the RDMA tree, then a
     fixup that went back and re-enabled the functions in the net tree
     and enabled their use in the rdma tree

     Also, a sparse fix was sent to the net tree after I did my pull,
     and the fixup patch conflicts quite directly with that sparse fix,
     so I'm going to submit the fixup patch towards the end of the merge
     window by itself and based upon your master branch at the time.

   - Two separate rounds of hfi1 fixes, one that got dropped from last
     release because it came in just a day or two before the end of the
     merge window and then the one from this release cycle.

     Of note is that I now have a third series that just landed from
     Intel yesterday. It is not included in this pull request, but I may
     submit it by the end of the week. I'll talk to Intel about
     improving the timing of thier submissions for my workflow.

   - Changes to our idr usage in the RDMA subsystem that will tie into
     our cgroup management and also into the upcoming changes for the
     RDMA kernel<->userspace API.

   - Addition of support for a netdev to be tied to an RDMA device at
     the core level

   - Addition of the VNIC driver from Intel.

     While IPoIB provides IP over InfiniBand (and *only* IP, no lower
     layer protocol headers are allowed or supported), the VNIC driver
     presents a virtual Ethernet device with support for things like
     varying Ethertypes, VLANs, priorities and other features of
     Ethernet.

     The virtual devices are centrally managed by the OPA fabric
     manager, making this (for the time being) a strictly OPA specific
     feature.

   - Improvements to the On-Demand Paging support in the RDMA subsystem.

   - Addition of three significant OPA changes.

     While we added OPA support some time ago (via the hfi1 driver), the
     RDMA subsystem has so far glossed over the areas where OPA and
     InfiniBand differ.

     With this release we are starting to add support for the OPA
     extensions into the RDMA core in the following area: Extended port
     information for OPA is now supported, extended Address Handle
     attributes for OPA are now supported, and extended SA Queries to
     get OPA specific subnet information is now supported.

  Concise summary from the tag:
   - idr usage and locking changes
   - build fix for hns
   - ipoib debug path record file fix
   - hfi1 updates
   - core RDMA netdev addition
   - Intel VNIC driver addition
   - Enhanced accelerators for IPoIB addition
   - Debug cleanups in cxgb3/4
   - Trivial cleanups from SF Markus Elfring
   - Misc rxe fixes from Mellanox
   - Misc ipoib fixes from Mellanox
   - Lots of mlx4/mlx5 changes from Mellanox
   - Misc fixes across the RDMA subsystem
   - ODP paging fixes and improvements
   - qedr updates
   - hfi1 updates
   - OPA port info patches
   - OPA AH patches
   - OPA SA Query patches"

Linus Torvalds 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).

Linus Torvalds a90f0e9ebb regulator: Updates for v4.12
Quite a lot going on with the regulator API for this release, much more
 in the core than in the drivers for a change:
 
  - Fixes for voltage change propagation through dumb power switches.
  - A notification when regulators are enabled.
  - A new settling time property for regulators where the time taken to
    move to a new voltage is not related to the size of the change.
  - Some reorganization of the Arizona drivers in preparation for sharing
    the code with the next generation devices they've been integrated
    with.
  - Support for newer Freescale chips in the Anatop regulator.
  - A new driver for voltage controlled regulators to cope with some

Linus Torvalds d35a878ae1 - A major update for DM cache that reduces the latency for deciding
whether blocks should migrate to/from the cache.  The bio-prison-v2
   interface supports this improvement by enabling direct dispatch of
   work to workqueues rather than having to delay the actual work
   dispatch to the DM cache core.  So the dm-cache policies are much more
   nimble by being able to drive IO as they see fit.  One immediate
   benefit from the improved latency is a cache that should be much more
   adaptive to changing workloads.
 
 - Add a new DM integrity target that emulates a block device that has
   additional per-sector tags that can be used for storing integrity
   information.
 
 - Add a new authenticated encryption feature to the DM crypt target that
   builds on the capabilities provided by the DM integrity target.
 
 - Add MD interface for switching the raid4/5/6 journal mode and update
   the DM raid target to use it to enable aid4/5/6 journal write-back
   support.
 
 - Switch the DM verity target over to using the asynchronous hash crypto
   API (this helps work better with architectures that have access to
   off-CPU algorithm providers, which should reduce CPU utilization).
 
 - Various request-based DM and DM multipath fixes and improvements from
   Bart and Christoph.
 
 - A DM thinp target fix for a bio structure leak that occurs for each
   discard IFF discard passdown is enabled.
 
 - A fix for a possible deadlock in DM bufio and a fix to re-check the
   new buffer allocation watermark in the face of competing admin changes
   to the 'max_cache_size_bytes' tunable.
 
 - A couple DM core cleanups.

Christophe Leroy 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.

Linus Torvalds 76f1948a79 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull livepatch updates from Jiri Kosina:

 - a per-task consistency model is being added for architectures that
   support reliable stack dumping (extending this, currently rather
   trivial set, is currently in the works).

   This extends the nature of the types of patches that can be applied
   by live patching infrastructure. The code stems from the design
   proposal made [1] back in November 2014. It's a hybrid of SUSE's
   kGraft and RH's kpatch, combining advantages of both: it uses
   kGraft's per-task consistency and syscall barrier switching combined
   with kpatch's stack trace switching. There are also a number of
   fallback options which make it quite flexible.

   Most of the heavy lifting done by Josh Poimboeuf with help from
   Miroslav Benes and Petr Mladek

Linus Torvalds 7af4c727c7 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
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

Linus Torvalds 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.

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.

Linus Torvalds c58d4055c0 A reasonably busy cycle for documentation this time around. There is a new
guide for user-space API documents, rather sparsely populated at the
 moment, but it's a start.  Markus improved the infrastructure for
 converting diagrams.  Mauro has converted much of the USB documentation
 over to RST.  Plus the usual set of fixes, improvements, and tweaks.
 
 There's a bit more than the usual amount of reaching out of Documentation/
 to fix comments elsewhere in the tree; I have acks for those where I could
 get them.

  clean away the most obvious architecture related parts. Removing dead
  code in drivers is the next step"

Notes from previous discussion about this:
 "The AVR32 architecture is not keeping up with the development of the
  kernel, and since it shares so much of the drivers with Atmel ARM SoC,
  it is starting to hinder these drivers to develop swiftly.

  Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now
  Microchip).

  Finally, the GCC toolchain is stuck at version 4.2.x, and has not
  received any patches since the last release from Atmel;
  4.2.4-atmel.1.1.3.avr32linux.1.

  When building kernel v4.10, this toolchain is no longer able to
  properly link the network stack.

  Haavard and I have came to the conclusion that we feel keeping AVR32
  on life support offers more obstacles for Atmel ARMs, than it gives
  joy to AVR32 users. I also suspect there are very few AVR32 users left
  today, if anybody at all"

That discussion was acked by Andy Shevchenko, Boris Brezillon, Nicolas
Ferre, and Haavard Skinnemoen.
