Pull media updates from Mauro Carvalho Chehab:
"Media updates for v4.12-rc1:
- new driver to support mediatek jpeg in hardware codec
- rc-lirc, s5p-cec and st-cec staging drivers got promoted
- hardware histogram support for vsp1 driver
- added Virtual Media Controller driver, to make easier to test the
media controller
- added a new CEC driver (rainshadow-cec)
- removed two staging LIRC drivers for obscure hardware that are too
obsolete
- added support for Intel SR300 Depth camera
- some improvements at CEC and RC core
- lots of driver cleanups, improvements all over the tree
With this series, we're finally getting rid of the LIRC staging
driver. There's just one left (lirc_zilog), with require more care,
as part of its functionality (IR RX) is already provided by another
driver. Work in progress to convert it on the proper way"

Pull regulator updates from Mark Brown:
"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
exciting ChromeOS hardware designs.

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
and variables to stay consistent"

When rebooting DOM0 with ACPI on ARM64, the kernel is crashing with the stack
trace [1].
This is happening because when EFI runtimes are enabled, the reset code
(see machine_restart) will first try to use EFI restart method.
However, the EFI restart code is expecting the reset_system callback to
be always set. This is not the case for Xen and will lead to crash.
The EFI restart helper is used in multiple places and some of them don't
not have fallback (see machine_power_off). So implement reset_system
callback as a call to xen_reboot when using EFI Xen.

The x86 code has theoritically a similar issue, altought EFI does not
seem to be the preferred method. I have only built test it on x86.
This should also probably be fixed in stable tree.
Changes in v2:
- Implement xen_efi_reset_system using xen_reboot
- Move xen_efi_reset_system in drivers/xen/efi.c

commit 815dd18788fe0d41899f51b91d0560279cf16b0d
Author: Bart Van Assche <bart.vanassche@sandisk.com>
Date: Fri Jan 20 13:04:04 2017 -0800
treewide: Consolidate get_dma_ops() implementations
rearranges get_dma_ops in a way that xen_dma_ops are not returned when
running on Xen anymore, dev->dma_ops is returned instead (see
arch/arm/include/asm/dma-mapping.h:get_arch_dma_ops and
include/linux/dma-mapping.h:get_dma_ops).
Fix the problem by storing dev->dma_ops in dev_archdata, and setting
dev->dma_ops to xen_dma_ops. This way, xen_dma_ops is returned naturally
by get_dma_ops. The Xen code can retrieve the original dev->dma_ops from
dev_archdata when needed. It also allows us to remove __generic_dma_ops
from common headers.

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
(Chanwoo Choi, Doug Smythies, Johan Hovold, Marcin Nowakowski)"

This patch also updates the definition of struct arizona_pdata and

Conflicts were simply overlapping changes. In the net/ipv4/route.c
case the code had simply moved around a little bit and the same fix
was made in both 'net' and 'net-next'.
In the net/sched/sch_generic.c case a fix in 'net' happened at
the same time that a new argument was added to qdisc_hash_add().

We found out that HW checksum generation only works from AST2500
onward. This disables it on AST2400 and removes the "no-hw-checksum"
properties in the device-trees. The problem we had wasn't related
to NC-SI.
Also rework the logic testing for that property so it can be used
to disable HW checksum generation and checking regardless of whether
NC-SI is used or not in case other variants out there need this.

We test for aspeed chips to handle a couple of special cases,
but we do that by checking the machine type which isn't right.
Instead check the actual device compatible property. This also
updates the dtsi files for the aspeed SoC to match.

The clocksource and the sched_clock provided by the arm_global_timer
are quite unstable because their rates depend on the cpu frequency.
On the other side, the arm_global_timer has a higher rating than the
rockchip_timer, it will be selected by default by the time framework
while we want to use the stable rockchip clocksource.
Let's disable the arm_global_timer in order to have the rockchip
clocksource selected by default.

The patch add two timers to all rk3188 based boards.
The first timer is from alive subsystem and it act as a backup
for the local timers at sleep time. It act the same as other
SoC rockchip timers already present in kernel.
The second timer is from CPU subsystem and act as replacement
for the arm-global-timer clocksource and sched clock. It run
at stable frequency 24MHz.

The Moxa Art interrupt controller is very very likely just an instance
of the Faraday FTINTC010 interrupt controller from Faraday Technology.
An indication would be its close association with the FA526 ARM core
and the fact that the register layout is the same.
The implementation in irq-moxart.c can probably be right off replaced
with the irq-ftintc010.c driver by adding a compatible string, selecting
this irqchip from the machine and run.
As a bonus we have an irqchip driver supporting high/low and
rising/falling edges for the Moxa Art, and shared code with the Gemini
platform.

common way of obtaining GPIO descriptor and away form legacy platform data.
