commit 198cf32f05 upstream.
Whilst this is another case of the issue Lars reported with
an array of elements of smaller than 8 bytes being passed
to iio_push_to_buffers_with_timestamp(), the solution here is
a bit different from the other cases and relies on __aligned
working on the stack (true since 4.6?)
This one is unusual. We have to do an explicit memset() each time
as we are reading 3 bytes into a potential 4 byte channel which
may sometimes be a 2 byte channel depending on what is enabled.
As such, moving the buffer to the heap in the iio_priv structure
doesn't save us much. We can't use a nice explicit structure
on the stack either as the data channels have different storage
sizes and are all separately controlled.

commit 8db4afe163 upstream.
One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
Here there is no data leak possibility so use an explicit structure
on the stack to ensure alignment and nice readable fashion.
The forced alignment of ts isn't strictly necessary in this driver
as the padding will be correct anyway (there isn't any). However
it is probably less fragile to have it there and it acts as
documentation of the requirement.

[ Upstream commit dee2dabc0e ]
Limit the output of humidity compensation to the range between 0 and 100
percent.
Depending on the calibration parameters of the individual sensor it
happens, that a humidity above 100 percent or below 0 percent is
calculated, which don't make sense in terms of relative humidity.
Add a clamp to the compensation formula as described in the datasheet of
the sensor in chapter 4.2.3.
Although this clamp is documented, it was never in the driver of the
kernel.
It depends on the circumstances (calibration parameters, temperature,
humidity) if one can see a value above 100 percent without the clamp.
The writer of this patch was working with this type of sensor without
noting this error. So it seems to be a rare event when this bug occures.

There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

This patch is trying to cleanup for good the buffers operation functions.
There is no need of using preenable, all can be done into
postenable. Let's also use logical sequence of operations as
already done in accel driver.
Finally also rename the goto label using operation to perform and not
where it fails.
Not stable material as not fixing a 'bug' but rather bringing the
driver in line with general 'patterns' to allow a subsystem wide
cleanup.

Before this commit sensor_hub_input_attr_get_raw_value() failed to take
the signedness of 16 and 8 bit values into account, returning e.g.
65436 instead of -100 for the z-axis reading of an accelerometer.
This commit adds a new is_signed parameter to the function and makes all
callers pass the appropriate value for this.
While at it, this commit also fixes up some neighboring lines where

According to IIO ABI relative humidity reading should be
returned in milli percent.
This patch addresses that by applying proper scaling and
returning integer instead of fractional format type specifier.
Note that the fixes tag is before the driver was heavily refactored
to introduce spi support, so the patch won't apply that far back.

A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.

DT bindings.
* stm32_adc
- Add support for STM32MP1 with bindings.

- White space and line break readability improvements.
- Reorder includes and variable declarations where appropriate.
* ad7791

tied to the resulting attribute, so it didn't work, and a warning
to be printed.
* ad7780
- Remove apparent support for sampling frequency control on devices
that don't support changing the sampling attributes.
* ade7854
- Fix a read of the wrong number of bits.

matter and the delays are long.
* bcm150
- Drop transaction splitting as core now handles it.
* cros_ec
- Move the shared header to the include/iio/common directory.
This brings it inline with the other multiple type devices.

- Use set_power_itg rather than opencoding it again in the i2c mux
control.
- Make sure error paths disable the power if undoing power on.
- Used managed devm_ functions during probe. Delete remove function.

* tsl2x7x (staging)
- Drop some unnecessary function calls, unused variables and
unnecessary local variables.
- Fix wrong interrupt type.
- Avoid unnecessary double clear of interrupt.
- Simplify proximity calibration call which did various things
unrelated to actually calibrating.
- Separate control of the proximity and ALS interrupts.
- Improve consistency of logging.
- Separate ALS and proximity persistence settings as they have
separate hardware controls.
- Tidy up variable ordering.
- Add Brian to copyright notice given consider work on this driver.
- Take advantage of hardware support for I2C address auto increment.
- Combine individuaal enable and period attributes for the two
directions on the threshold events into a single value as the
hardware doesn't separate them.
- Move integration_time* attributes from light channel to
intensity value as they effect the intensity readings directly
and the light reading only indirectly. Hence this better
reflects reality. Also move the calibscale_available.
- Avoid returning an error in the IRQ handler.
- Hard code the reg value in _clear_interrupts as it only takes
one value in the code. Result is the function has little
purpose so opencode the two remaining i2c_smbus_write_byte
calls.
- Drop some unnecessary checking of the chip status register.
- Tidy up return path in _write_interrupt_config.
- Tidy up the ID verification code.
- Move the power and diode settings defines into the header as these
are needed for platform data configuration.
- Various renames and comment cleanups for consistency and clarity.
- Use actual device defaults for default startup settings.
- SPDX
- Add some range sanity checking to sysfs attribute writes.
- Don't provide event interfaces if the interrupt line isn't available.
- Use IIO_CONST_ATTR macro for calibscale_available as it's a constant
string.
- Fix the integration time and lux equations.
- Make device IDs explicit index values in the device_channel_config array.

Commit 7383d44b added a pointer pdata which get set to the default
platform_data when non was defined in the device. But it did not
pass this pointer to the st_sensors_init_sensor call but still
used the maybe uninitialized platform_data from dev.
This breaks initialization when no platform_data is given and
the optional st,drdy-int-pin devicetree option is not set.
This commit fixes this.

This patch affects BME280 and BMP280. The readout of the calibration
data is moved to the probe function. Each sensor data access triggered
reading the full calibration data before this patch. According to the
datasheet, Section 4.4.2., the calibration data is stored in non-volatile
memory.
Since the calibration data does not change, and cannot be changed by the
user, we can reduce bus traffic by reading the calibration data once.
Additionally, proper organization of the data types enables removing
some odd casts in the compensation formulas.

Here is the "big" staging and IIO driver update for 4.15-rc1.
Lots and lots of little changes, almost all minor code cleanups as the
Outreachy application process happened during this development cycle.
Also happened was a lot of IIO driver activity, and the typec USB code
moving out of staging to drivers/usb (same commits are in the USB tree
on a persistent branch to not cause merge issues.)
Overall, it's a wash, I think we added a few hundred more lines than
removed, but really only a few thousand were modified at all.
All of these have been in linux-next for a while. There might be a
merge issue with Al's vfs tree in the pi433 driver (take his changes,
they are always better), and the media tree with some of the odd atomisp
cleanups (take the media tree's version).

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.
