Pull pin control fixes from Linus Walleij:
"Here is an overdue pull request for pin control fixes, the most
prominent feature is to make Intel Chromebooks (and I suspect any
other Cherryview-based Intel thing) happy again, which we really want
to see.
There is a patch hitting drivers/firmware/* that I was uncertain to
who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's
review tags on it and I trust them both 100% to do the right thing for
Intel platform drivers.
Summary:
- Make a few Intel Chromebooks with Cherryview DMI firmware work
smoothly.
- A fix for some bogus allocations in the generic group management
code.
- Some GPIO descriptor lookup table stubs. Merged through the pin
control tree for administrative reasons.
- Revert the "bi-directional" and "output-enable" generic properties:
we need more discussions around this. It seems other SoCs are using
input/output gate enablement and these terms are not correct.
- Fix mux and drive strength atomically in the MXS driver.
- Fix the SPDIF function on sunxi A83T.
- OF table terminators and other small fixes"

This reverts commit 8c58f1a7a4b6d1d723bf25fef9d842d5a11200d0.
It turns out that applying these generic properties was
premature: the properties used in the driver using this
are of unclear electrical nature and the subject need to
be discussed.

git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer fixes from Dmitry Torokhov:
"Just a few fixups to a couple of drivers"

Input: elan_i2c - ignore signals when finishing updating firmware

The datasheet and application note does not mention an allowed range for
the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set
lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with
T5x06 touch.
So, lacking a known lower limit, we increase the range for thresholds,
and set the lower limit to 0. The documentation is updated accordingly.

Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.
If the DT property is not given, no delay is observed. Post reset delay
greater than 1000ms are invalid.

During power off, after the GPIO pin has been asserted, some devices like
the Wifi chip from TI, Wl18xx, needs a delay before the host continues with
clock gating and turning off regulators as to follow a graceful shutdown
sequence.
Therefore invent an optional power-off-delay-us DT binding for
mmc-pwrseq-simple, to allow us to support this constraint.

This reverts commit ecb10b694b72ca5ea51b3c90a71ff2a11963425a.
The only expected ACPI control method lid device's usage model is
1. Listen to the lid notification,
2. Evaluate _LID after being notified by BIOS,
3. Suspend the system (if users configure to do so) after seeing "close".
It's not ensured that BIOS will notify OS after boot/resume, and
it's not ensured that BIOS will always generate "open" event upon
opening the lid.
But there are 2 wrong usage models:
1. When the lid device is responsible for suspend/resume the system,
userspace requires to see "open" event to be paired with "close" after
the system is resumed, or it will suspend the system again.
2. When an external monitor connects to the laptop attached docks,
userspace requires to see "close" event after the system is resumed so
that it can determine whether the internal display should remain dark
and the external display should be lit on.
After we made default kernel behavior to be suitable for usage model 1,
users of usage model 2 start to report regressions for such behavior
change.
Reversion of button.lid_init_state=method doesn't actually reverts to old
default behavior as doing so can enter a regression loop, but facilitates
users to work the reported regressions around with
button.lid_init_state=method.

The ICH9 is listed as having TCO v2, and indeed the behavior in the
datasheet corresponds to v2 (for example the NO_REBOOT flag is
accessible via the 16KiB-aligned Root Complex Base Address).
However, the TCO counts twice just like in v1; the documentation
of the SECOND_TO_STS bit says: "ICH9 sets this bit to 1 to indicate
that the TIMEOUT bit had been (or is currently) set and a second
timeout occurred before the TCO_RLD register was written. If this
bit is set and the NO_REBOOT config bit is 0, then the ICH9 will
reboot the system after the second timeout. The same can be found
in the BayTrail (Atom E3800) datasheet, and even HOWTOs around
the Internet say that it will reboot after _twice_ the specified
heartbeat.
I did not find the Apollo Lake datasheet, but because v4/v5 has
a SECOND_TO_STS bit just like the previous version I'm enabling
this for Apollo Lake as well.

This patch adds the DT binding documentation for the battery power
supply which gets various data from the PMIC, such as the battery status
(charging, discharging, full, dead), current max limit, current current,
battery capacity (in percentage), voltage max and min limits, current
voltage and battery capacity (in Ah).

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)

Device tree binding information for DA9062 and DA9061 thermal junction
temperature monitor.
Binding descriptions for the DA9061 and DA9062 thermal TJUNC supervisor
device driver, using a single THERMAL_TRIP_HOT trip-wire and allowing for
a configurable polling period for over-temperature polling.
This patch also adds two examples, one for DA9062 and one for DA9061. The
DA9061 example uses a fall-back compatible string for the DA9062.

This commit documents binding for thermal used in Northstar family SoCs.
There isn't any known Northstar device with active cooling system so DT
example has empty cooling-maps node. There is also no support for CPU
frequency throttling so I put only a critical trip in the example.

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.

Pull SCSI target updates from Nicholas Bellinger:
"Things were a lot more calm than previously expected. It's primarily
fixes in various areas, with most of the new functionality centering
around TCMU backend driver work that Xiubo Li has been driving.
Here's the summary on the feature side:
- Make T10-PI verify configurable for emulated (FILEIO + RD) backends
(Dmitry Monakhov)
- Allow target-core/TCMU pass-through to use in-kernel SPC-PR logic
(Bryant Ly + MNC)
- Add TCMU support for growing ring buffer size (Xiubo Li + MNC)
- Add TCMU support for global block data pool (Xiubo Li + MNC)
and on the bug-fix side:
- Fix COMPARE_AND_WRITE non GOOD status handling for READ phase
failures (Gary Guo + nab)
- Fix iscsi-target hang with explicitly changing per NodeACL
CmdSN number depth with concurrent login driven session
reinstatement. (Gary Guo + nab)
- Fix ibmvscsis fabric driver ABORT task handling (Bryant Ly)
- Fix target-core/FILEIO zero length handling (Bart Van Assche)
Also, there was an OOPs introduced with the WRITE_VERIFY changes that
I ended up reverting at the last minute, because as not unusual Bart
and I could not agree on the fix in time for -rc1. Since it's specific
to a conformance test, it's been reverted for now.
There is a separate patch in the queue to address the underlying
control CDB write overflow regression in >= v4.3 separate from the
WRITE_VERIFY revert here, that will be pushed post -rc1"

The script can serve as a starting point for people that cannot use

Pull more powerpc updates from Michael Ellerman:
"The change to the Linux page table geometry was delayed for more
testing with 16G pages, and there's the new CPU features stuff which
just needed one more polish before going in. Plus a few changes from
Scott which came in a bit late. And then various fixes, mostly minor.
Summary highlights:
- rework the Linux page table geometry to lower memory usage on
64-bit Book3S (IBM chips) using the Hash MMU.
- support for a new device tree binding for discovering CPU features
on future firmwares.
- Freescale updates from Scott:
"Includes a fix for a powerpc/next mm regression on 64e, a fix for
a kernel hang on 64e when using a debugger inside a relocated
kernel, a qman fix, and misc qe improvements."
Thanks to: Christophe Leroy, Gavin Shan, Horia Geantă, LiuHailong,
Nicholas Piggin, Roy Pledge, Scott Wood, Valentin Longchamp"

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.

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.

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.

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.
