10c8251cce thermal: qcom-spmi-temp-alarm: add support for GEN2 PMIC peripherals
Add support for the TEMP_ALARM GEN2 PMIC peripheral subtype.  The
GEN2 subtype defines an over temperature state with hysteresis
instead of stage in the status register.  There are two GEN2
states corresponding to stages 1 and 2.

d8e3a61318 thermal: int340x: Prevent error in reading trip hysteresis attribute
Some of the INT340X devices may not have hysteresis defined in the ACPI
definition. In that case reading trip hysteresis results in error. This
spams logs of user space utilities.

In this case instead of returning error, just return hysteresis as 0,
which is correct as there is no hysteresis defined for the device.

33e678d47d thermal: Shorten name of sysfs callbacks
The naming isn't consistent across all sysfs callbacks in the thermal
core, some have a short name like type_show() and others have long names
like thermal_cooling_device_weight_show(). This patch tries to make it
consistent by shortening the name of sysfs callbacks.

Some of the sysfs files are named similarly for both thermal zone and
cooling device (like: type) and to avoid name clash between their
show/store routines, the cooling device specific sysfs callbacks are
prefixed with "cdev_".

f085f672b7 thermal: imx: add i.MX7 thermal sensor support
This patch adds i.MX7 thermal sensor support, most
of the i.MX7 thermal sensor functions are same with
i.MX6 except the registers offset/layout, so we move
those registers offset/layout definitions to soc data
structure.

i.MX7 uses single calibration data @25C, the calibration
data is located at OCOTP offset 0x4F0, bit[17:9], the
formula is as below:

Tmeas = (Nmeas - n1) + 25; n1 is the fuse value for 25C.

88fc6f73fd thermal: exynos: Reading temperature makes sense only when TMU is turned on
When thermal sensor is not yet enabled, reading temperature might return

has been actually enabled before reading the temperature.

This change fixes booting of Exynos4210-based board with TMU enabled (for

8ea229511e thermal: Add cooling device's statistics in sysfs
This extends the sysfs interface for thermal cooling devices and exposes
some pretty useful statistics. These statistics have proven to be quite
useful specially while doing benchmarks related to the task scheduler,
where we want to make sure that nothing has disrupted the test,
specially the cooling device which may have put constraints on the CPUs.
The information exposed here tells us to what extent the CPUs were
constrained by the thermal framework.

The write-only "reset" file is used to reset the statistics.

The read-only "time_in_state_ms" file shows the time (in msec) spent by the
device in the respective cooling states, and it prints one line per
cooling state.

The read-only "total_trans" file shows single positive integer value
showing the total number of cooling state transitions the device has
gone through since the time the cooling device is registered or the time
when statistics were reset last.

The read-only "trans_table" file shows a two dimensional matrix, where
an entry <i,j> (row i, column j) represents the number of transitions
from State_i to State_j.

This is how the directory structure looks like for a single cooling
device:

$ ls -R /sys/class/thermal/cooling_device0/
/sys/class/thermal/cooling_device0/:
cur_state  max_state  power  stats  subsystem  type  uevent

/sys/class/thermal/cooling_device0/power:
autosuspend_delay_ms  runtime_active_time  runtime_suspended_time
control               runtime_status

/sys/class/thermal/cooling_device0/stats:
reset  time_in_state_ms  total_trans  trans_table

This is tested on ARM 64-bit Hisilicon hikey620 board running Ubuntu and
ARM 64-bit Hisilicon hikey960 board running Android.

cf1ba1d73a thermal: imx: Fix race condition in imx_thermal_probe()
When device boots with T > T_trip_1 and requests interrupt,
the race condition takes place. The interrupt comes before
THERMAL_DEVICE_ENABLED is set. This leads to an attempt to
reading sensor value from irq and disabling the sensor, based on
the data->mode field, which expected to be THERMAL_DEVICE_ENABLED,
but still stays as THERMAL_DEVICE_DISABLED. Afher this issue
sensor is never re-enabled, as the driver state is wrong.

Fix this problem by setting the 'data' members prior to
requesting the interrupts.

e782bc169c thermal: thermal_hwmon: Convert to hwmon_device_register_with_info()
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 7611fb6806 ("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 3feb479cea ("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 74d3b64197 ("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.

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.

2f28e4c24b thermal: armada: Clarify control registers accesses
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.

4e5f61ca11 thermal: imx: update to new formula according to NXP AN5215
According to an application note from 03/2017 there is an updated formula to
calculate the temperature that better matches reality. This is implemented here.

While updating move the magic constants from cpp defines which are far above the
explaining formula to constants in the code just under the explaining comment.

c5bbdb4ba3 thermal: imx: improve comments describing algorithm for temp calculation
The description of the implemented algorithm is hardly understandable
without having the right application note side-by-side to the code.

Fix this by using shorter and more intuitive variable names, describe
their meaning and transform a single formula instead of first talking about
slope and then about "milli_Tmeas".

There are no code changes.

b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
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.

9e03cf1b2d thermal: add brcmstb AVS TMON driver
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.
