Pull driver core updates from Greg KH:
"Here is the set of "big" driver core patches for 4.16-rc1.
The majority of the work here is in the firmware subsystem, with
reworks to try to attempt to make the code easier to handle in the
long run, but no functional change. There's also some tree-wide sysfs
attribute fixups with lots of acks from the various subsystem
maintainers, as well as a handful of other normal fixes and changes.
And finally, some license cleanups for the driver core and sysfs code.
All have been in linux-next for a while with no reported issues"

Booting Linux on a mx6q based board leads to the following warning:
(NULL device *): hwmon_device_register() is deprecated. Please convert the
driver to use hwmon_device_register_with_info().
, so do the conversion as suggested.
Also, this results in the core taking care of creating the 'name'
attribute, so drop the code doing that from the thermal driver.
The initial attempt to convert this driver to
hwmon_device_register_with_info() caused issues on the N900 platform
in commit 7611fb68062f ("thermal: thermal_hwmon: Convert to
hwmon_device_register_with_info()"):
bq27xxx-battery 2-0055: failed to register battery
bq27xxx-battery: probe of 2-0055 failed with error -22
...
rx51-battery: probe of n900-battery failed with error -22
, leading to a revert in commit 3feb479cea37 ("Revert "thermal:
thermal_hwmon: Convert to hwmon_device_register_with_info()"").
The probe errors happened due to the '-' character being present in
the name of the power supply devices: bq27200-0 and rx51-battery.
Since commit 74d3b6419772 ("hwmon: Relax name attribute validation
for new APIs") hwmon will no longer treat these names as errors,
allowing the transition for hwmon_device_register_with_info() to
happen in a safely manner.

When exposing data access through debugfs, the correct
debugfs_create_*() functions must be used, depending on data type.
Remove all casts from data pointers passed to debugfs_create_*()
functions, as such casts prevent the compiler from flagging bugs.

After registration to the thermal core, sysfs will make one entry
per instance of the driver in /sys/class/thermal_zoneX and
/sys/class/hwmon/hwmonX, X being the index of the instance, all of them
having the type/name "armada_thermal".
Until now there was only one thermal zone per SoC but SoCs like Armada
A7K and Armada A8K have respectively two and three thermal zones (one
per AP and one per CP) and this number is subject to grow in the future.
Use dev_name() instead of the "armada_thermal" string to get a
meaningful name and be able to identify the thermal zones from
userspace.

The thermal core will check for sensors validity right after the
initialization callback has returned. As the initialization routine make
a reset, the sensors are not ready immediately and the core spawns an
error in the dmesg. Avoid this annoying situation by polling on the
validity bit before exiting from these routines. This also avoid the use
of blind sleeps.

Three 32-bit registers are used to drive the thermal IP: control0,
control1 and status. The two control registers share the same name both
in the documentation and in the code, while the latter is referred as
"sensor" in the code. Rename this pointer to be called "status" in order
to be aligned with the documentation.

Bindings were incomplete for a long time by only exposing one of the two
available control registers. To ease the migration to the full bindings
(already in use for the Armada 375 SoC), rename the pointers for
clarification. This way, it will only be needed to add another pointer
to access the other control register when the time comes.
This avoids dangerous situations where the offset 0 of the control
area can be either one register or the other depending on the bindings
used. After this change, device trees of other SoCs could be migrated to
the "full" bindings if they may benefit from features from the
unaccessible register, without any change in the driver.

All Armada SoCs use one bit to declare if the sensor values are valid.
This bit moves across the versions of the IP.
The method until then was to do both a shift and compare with an useless
flag of "0x1". It is clearer and quicker to directly save the value that
must be ANDed instead of the bit position and do a single bitwise AND
operation.

Remove current implementation of of_cpufreq_cooling_register() and

"This branch contains platform-related driver updates for ARM and
ARM64, these are the areas that bring the changes:
New drivers:
- driver support for Renesas R-Car V3M (R8A77970)
- power management support for Amlogic GX
- a new driver for the Tegra BPMP thermal sensor
- a new bus driver for Technologic Systems NBUS
Changes for subsystems that prefer to merge through arm-soc:
- the usual updates for reset controller drivers from Philipp Zabel,
with five added drivers for SoCs in the arc, meson, socfpa,
uniphier and mediatek families
- updates to the ARM SCPI and PSCI frameworks, from Sudeep Holla,
Heiner Kallweit and Lorenzo Pieralisi
Changes specific to some ARM-based SoC
- the Freescale/NXP DPAA QBMan drivers from PowerPC can now work on
ARM as well
- several changes for power management on Broadcom SoCs
- various improvements on Qualcomm, Broadcom, Amlogic, Atmel,
Mediatek
- minor Cleanups for Samsung, TI OMAP SoCs"
[ NOTE! This doesn't work without the previous ARM SoC device-tree pull,
because the R8A77970 driver is missing a header file that came from
that pull.
The fact that this got merged afterwards only fixes it at this point,
and bisection of that driver will fail if/when you walk into the
history of that driver. - Linus ]

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The AVS TMON core provides temperature readings, a pair of configurable
high- and low-temperature threshold interrupts, and an emergency
over-temperature chip reset. The driver utilizes the first two to
provide temperature readings and high-temperature notifications to
applications. The over-temperature reset is not exposed to
applications; this reset threshold is critical to the system and should
be set with care within the bootloader.
Applications may choose to utilize the notification mechanism, the
temperature reading mechanism (e.g., through polling), or both.

As the next patches will provide support for the hikey3660's sensor,
several functions with the same purpose but for different platforms will
be introduced.
In order to make a clear distinction between them, let's prefix the
function names with the platform name.
This patch has no functional changes, only name changes.

Everything mentionned here:
https://lkml.org/lkml/2016/4/20/850
This driver was added before the devm_iio_channel_get() function version was
merged. The sensor should be released before the iio channel, thus we had to
use the non-devm version of thermal_zone_of_sensor_register().
Now the devm_iio_channel_get() is available, do the corresponding change in
this driver and remove gadc_thermal_remove().
