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
and variables to stay consistent"

Pull AVR32 removal from Hans-Christian Noren Egtvedt:
"This will remove support for AVR32 architecture from the kernel and
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.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/egtvedt/linux-avr32:

Pull power management updates from Rafael Wysocki:
"This time the majority of changes go to the cpufreq subsystem (and to
the intel_pstate driver in particular) and there are some updates in
the generic power domains framework, cpuidle, tools and a couple of
other places.
One thing worth mentioning is that the intel_pstate's sysfs interface
has been reworked to be more consistent with the general expectations
of the cpufreq core and less confusing, hopefully for the better.
Also, we have a new cpufreq driver for Tegra186 and new hardware
support in intel_pstata and the Mediatek cpufreq driver.
Apart from that, the AnalyzeSuspend utility for system suspend
profiling gets a companion called AnalyzeBoot for the analogous
profiling of system boot and they both go into one place under
tools/power/pm-graph/.
The rest is mostly fixes, cleanups and code reorganization.
Specifics:
- Rework the intel_pstate driver's sysfs interface to make it more
straightforward and more intuitive (Rafael Wysocki).
- Make intel_pstate support all processors which advertise HWP
(hardware-managed P-states) to the kernel in all operation modes
and make it use the load-based P-state selection algorithm on a
wider range of systems in the active mode (Rafael Wysocki).
- Add cpufreq driver for Tegra186 (Mikko Perttunen).
- Add support for Gemini Lake SoCs to intel_pstate (David Box).
- Add support for MT8176 and MT817x to the Mediatek cpufreq driver
and clean up that driver a bit (Daniel Kurtz).
- Clean up intel_pstate and optimize it slightly (Rafael Wysocki).
- Update the schedutil cpufreq governor, mostly to fix a couple of
issues with it related to specific workloads, and rework its sysfs
tunable and initialization a bit (Rafael Wysocki, Viresh Kumar).
- Fix minor issues in the imx6q, dbx500 and qoriq cpufreq drivers
(Christophe Jaillet, Irina Tirdea, Leonard Crestez, Viresh Kumar,
YuanTian Tang).
- Add file patterns for cpufreq DT bindings to MAINTAINERS (Geert
Uytterhoeven).
- Add support for "always on" power domains to the genpd (generic
power domains) framework and clean up that code somewhat (Ulf
Hansson, Lina Iyer, Viresh Kumar).
- Fix minor issues in the powernv cpuidle driver and clean it up
(Anton Blanchard, Gautham Shenoy).
- Move the AnalyzeSuspend utility under tools/power/pm-graph/ and add
an analogous boot-profiling utility called AnalyzeBoot to it (Todd
Brandt).
- Add rk3328 support to the rockchip-io AVS (Adaptive Voltage
Scaling) driver (David Wu).
- Fix minor issues in the cpuidle core, the intel_pstate_tracer
utility, the devfreq framework and the PM core documentation

Pull block layer updates from Jens Axboe:
- Add BFQ IO scheduler under the new blk-mq scheduling framework. BFQ
was initially a fork of CFQ, but subsequently changed to implement
fairness based on B-WF2Q+, a modified variant of WF2Q. BFQ is meant
to be used on desktop type single drives, providing good fairness.
From Paolo.
- Add Kyber IO scheduler. This is a full multiqueue aware scheduler,
using a scalable token based algorithm that throttles IO based on
live completion IO stats, similary to blk-wbt. From Omar.
- A series from Jan, moving users to separately allocated backing
devices. This continues the work of separating backing device life
times, solving various problems with hot removal.
- A series of updates for lightnvm, mostly from Javier. Includes a
'pblk' target that exposes an open channel SSD as a physical block
device.
- A series of fixes and improvements for nbd from Josef.
- A series from Omar, removing queue sharing between devices on mostly
legacy drivers. This helps us clean up other bits, if we know that a
queue only has a single device backing. This has been overdue for
more than a decade.
- Fixes for the blk-stats, and improvements to unify the stats and user
windows. This both improves blk-wbt, and enables other users to
register a need to receive IO stats for a device. From Omar.
- blk-throttle improvements from Shaohua. This provides a scalable
framework for implementing scalable priotization - particularly for
blk-mq, but applicable to any type of block device. The interface is
marked experimental for now.
- Bucketized IO stats for IO polling from Stephen Bates. This improves
efficiency of polled workloads in the presence of mixed block size
IO.
- A few fixes for opal, from Scott.
- A few pulls for NVMe, including a lot of fixes for NVMe-over-fabrics.
From a variety of folks, mostly Sagi and James Smart.
- A series from Bart, improving our exposed info and capabilities from
the blk-mq debugfs support.
- A series from Christoph, cleaning up how handle WRITE_ZEROES.
- A series from Christoph, cleaning up the block layer handling of how
we track errors in a request. On top of being a nice cleanup, it also
shrinks the size of struct request a bit.
- Removal of mg_disk and hd (sorry Linus) by Christoph. The former was
never used by platforms, and the latter has outlived it's usefulness.
- Various little bug fixes and cleanups from a wide variety of folks.

This patch drops support for AVR32 architecture from the Linux kernel.
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.

Linux 4.11-rc1

This is a complete rewrite of the driver whose main purpose is to
support the new DT representation where the NAND controller node is now
really visible in the DT and appears under the EBI bus. With this new
representation, we can add other devices under the EBI bus without
risking pinmuxing conflicts (the NAND controller is under the EBI
bus logic and as such, share some of its pins with other devices
connected on this bus).
Even though the goal of this rework was not necessarily to add new
features, the new driver has been designed with this in mind. With a
clearer separation between the different blocks and different IP
revisions, adding new functionalities should be easier (we already
have plans to support SMC timing configuration so that we no longer
have to rely on the configuration done by the bootloader/bootstrap).
Also note that we no longer have a custom ->cmdfunc() implementation,
which means we can now benefit from new features added in the core
implementation for free (support for new NAND operations for example).
The last thing that we gain with this rework is support for multi-chips
and multi-dies chips, thanks to the clean NAND controller <-> NAND
devices representation.
During this transition we also dropped support for AVR32 SoCs which
should soon disappear from mainline (removal of the AVR32 arch is
planned for 4.12).
This new driver has been tested on several platforms (at91sam9261,
at91sam9g45, at91sam9x5, sama5d3 and sama5d4) to make sure it did not
introduce regressions, and it's worth mentioning that old bindings are
still supported (which partly explain the positive diffstat).

Armada 370/XP devices can 'blink' GPIO lines with a configurable on
and off period. This can be modelled as a PWM.
However, there are only two sets of PWM configuration registers for
all the GPIO lines. This driver simply allows a single GPIO line per
GPIO chip of 32 lines to be used as a PWM. Attempts to use more return
EBUSY.
Due to the interleaving of registers it is not simple to separate the
PWM driver from the GPIO driver. Thus the GPIO driver has been
extended with a PWM driver.

Replace existing hw_ranndom/exynos-rng driver with a new, reworked one.
This is a driver for pseudo random number generator block which on
Exynos4 chipsets must be seeded with some value. On newer Exynos5420
chipsets it might seed itself from true random number generator block
but this is not implemented yet.
New driver is a complete rework to use the crypto ALGAPI instead of
hw_random API. Rationale for the change:
1. hw_random interface is for true RNG devices.
2. The old driver was seeding itself with jiffies which is not a
reliable source for randomness.
3. Device generates five random 32-bit numbers in each pass but old
driver was returning only one 32-bit number thus its performance was
reduced.
Compatibility with DeviceTree bindings is preserved.
New driver does not use runtime power management but manually enables
and disables the clock when needed. This is preferred approach because
using runtime PM just to toggle clock is huge overhead.
Another difference is reseeding itself with generated random data
periodically and during resuming from system suspend (previously driver
was re-seeding itself again with jiffies).
