All devices using a triggered buffer need to attach and detach the trigger
to the device in order to properly work. Instead of doing this in each and
every driver by hand move this into the core.
At this point in time, all drivers should have been resolved to
attach/detach the poll-function in the same order.
This patch removes all explicit calls of iio_triggered_buffer_postenable()
& iio_triggered_buffer_predisable() in all drivers, since the core handles
now the pollfunc attach/detach.
The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's
not immediately obvious that removing the hooks doesn't break anything.
Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board.

This assignment is the more peculiar as it assigns the parent of the
platform-device's device (i.e. pdev->dev.parent) as the IIO device's
parent.
Since the devm_iio_device_alloc() [now] assigns the device argument as the
default parent (and since this is the more common case), for cases
where the parent needs to be different, the iio_device_set_parent helper
should be used.
That makes things a bit more obvious about the new behavior of
devm_iio_device_alloc() and makes it clearer that iio_device_set_parent()
should be used.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

We may want to get rid of the iio_priv_to_dev() helper. That's a bit
uncertain at this point. The reason is that we will hide some of the
members of the iio_dev structure (to prevent drivers from accessing them
directly), and that will also mean hiding the implementation of the
iio_priv_to_dev() helper inside the IIO core.
Hiding the implementation of iio_priv_to_dev() implies that some fast-paths
may not be fast anymore, so a general idea is to try to get rid of the
iio_priv_to_dev() altogether.
For this driver, removing iio_priv_to_dev() means keeping a reference

Use units of 1/100000th for calibscale and lux_per_bit. The similar

This allows for higher-accuracy and makes it easier to add support
for getting device-specific calibscale and lux_per_bit values from
a device's ACPI tables, as the values in the ACPI tables also use
1/100000th units.
This units change means that our intermediate values in cm32181_get_lux()

Some ACPI systems list 2 I2C resources for the CM3218 sensor. On these
systems the first I2cSerialBus ACPI-resource points to the SMBus Alert
Response Address (ARA, 0x0c) and the second I2cSerialBus ACPI-resource
points to the actual CM3218 sensor address:
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (SBUF, ResourceTemplate ()
{
I2cSerialBusV2 (0x000C, ControllerInitiated, 0x00061A80,
AddressingMode7Bit, "\\_SB.I2C3",
0x00, ResourceConsumer, , Exclusive,

{
0x00000033,
}
})
Return (SBUF) /* \_SB_.I2C3.ALSD._CRS.SBUF */
}
Detect this and take the following step to deal with it:
1. When a SMBus Alert capable sensor has an Alert asserted, it will
not respond on its actual I2C address. Read a byte from the ARA
to clear any pending Alerts.
2. Create a "dummy" client for the actual I2C address and
use that client to communicate with the sensor.

The main intent here is to get rid of the iio_buffer_set_attrs() helper, or
at least rework it's usage a bit.
The problem with that helper is that it needs a pointer to the buffer,
which makes supporting multiple buffers per IIO device a bit more
cumbersome.
The hid_sensor_setup_trigger() is pretty much used in the same way:
- iio_triggered_buffer_setup() gets called before
- then hid_sensor_setup_trigger() and hid_sensor_setup_batch_mode() gets
called which may attach some fifo attributes
This change merges the 2 together under the hid_sensor_setup_trigger()
function. Only the &iio_pollfunc_store_time is passed to all devices, so
it's not even required to pass it explicitly outside of the common
hid_sensor_setup_trigger() function.
Moving the devm_iio_triggered_buffer_setup/cleanup() calls into the common
place code can help the rework of the buffer code, since it is in one
place.
One detail of the change is that there are 2 drivers that use
devm_iio_triggered_buffer_setup(). That function gets implicitly
replaced with iio_triggered_buffer_setup()/cleanup(), but since all drivers
call both hid_sensor_setup_trigger9) & hid_sensor_remove_trigger() trigger,
the iio_triggered_buffer_cleanup() piggy backs on the
hid_sensor_remove_trigger() call, which should cover the cleanup.

Jonathan writes:
First set of new IIO device support, features and cleanup for the 5.8 cycle
Usual mix of new drivers, new support in old drivers and lots of minor
cleanup. Yaml conversions also continue to trickle in (plenty more to go!)
New device support
* ad7476
- Add ad7091 support (ID only)
* ad9467
- New driver for this 200/250 MSPS adi-axi-adc and SPI attached ADC.
* adi-axi-adc
- New driver to support ADIs generic AXI ADC IP core, used to provide
high speed interfaces to ADCs (JESD204B/C or parallel interfaces). Usually
paired with a device using a slow configuration interface (spi etc)
Includes DT bindings and some fixes for fpga headers.
* bmg160
- Add support for BMI088 (ID only)
* max1241
- New driver for this ADC.
* st_sensors
- Add support for LIS2HH12 accelerometer
* sx9310
- New driver supporting sx9310 and sx9311 proximity sensors.
Yaml DT binding conversions
* rockchip-saradc (including adding some missing parts)
* stm32-dac
* tsl2563
* vcnl4000
Features
* st_lsm6dsx
- Add LIS3MDL as a possible sensor hub device.
* vcnl4000
- Add new concept of near level (from DT) to provide to userspace which
often needs to have some calibrated concept of 'near'.
Cleanups, minor fixes etc.
* core
- Use snprintf for functions where strings are built and there is
potential for overflow.
- Correct docs to indicate mlock should not be used directly by drivers.
- Fix up accidental dropping of a patch to use bitmap_zalloc.
- Stop allowing enabling of buffers with no channels enabled.
- Drop unused 'stufftoread' from iio_buffer.
- Drop scan_el_attrs form iio_buffer as unused.
- Reorder sanity checks in __iio_device_register to fail earlier.
- Drop all the devm_ runregister / free functions from IIO as they
were never used and encourage poor design.
* dma-buffer
- Tidy up includes.
* dma-engine-buffer
- Provide dev-managed allocator.
- Fix an issue with printing a size_t
* cross subsystem (kxsd9, bmg160, mpu3050, bmi160, mpu6050, bmc150)
- Replace some unnecessary casts of error ptrs and whilst there.
use the %pe printf parameter to print them in a more useful fashion.
* cross subsystem
- Drop casts in calls to regmap_bulk_read as they make no sense.
- Use devm_platform_ioremap_resource to reduce boilerplate.
- Fix typos in Analog Devices.
* counters/104-quad
- Add Syed Nayyar Waris as an additional maintainer.
* ad7476
- Generate CONVST signal internally rather than requiring external
trigger. Add sysfs read back as can now do so.
- use devm_add_action_or_reset to tidy up error and remove handling.
* ad7793
- Switch to read_avail from explicit attribute. Mostly done to avoid
confusing people with a - sign (without surounding spaces) that
was correct but checkpatch didn't like.
* adis library
- Add missing newlines at end of error messages.
* adis16400
- Use DEFINE_DEBUGS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTR.
* adis16460
- Use DEFINE_DEBUGS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTR.
* ad_sigma_delta
- Move some channel definitions into individual drivers to avoid
having to deal with complex options.
* ak8974
- Silence an error on deffered probe.
* bmp280
- Harden against IRQ before registration.
- Convert to read_avail instead of opencoding the equivalent.
- Explicitly mark GPIO as optional.
- Cleanup casts.
- Remove line breaks from strings.
* htts221
- Replace direct access to platform_data with dev_get_platdata().
- Use device properties rather than device tree ones to allow ACPI
probing.
- Casting cleanups.
* intel_mrfld_adc
- Don't use unaligned accessor for aligned data.

When an object can be considered close to the sensor is hardware
dependent. Allowing to configure the property via device tree
allows to configure this device specific value.
This is useful for e.g. iio-sensor-proxy to indicate to userspace
if an object is close to the sensor.

The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.
For the predisable hook, the disable code should occur before detaching
the poll func, and for the postenable hook, the poll func should be
attached before the enable code.
This change reworks the predisable/postenable hooks so that the pollfunc is
attached/detached in the correct position.
It also balances the calls a bit, by grouping the preenable and the
iio_triggered_buffer_postenable() into a single
isl29125_buffer_postenable() function.

snprintf() is a hard-to-use function, it's especially difficult to use
it for concatenating substrings in a buffer with a limited size.
Since snprintf() returns the would-be-output size, not the actual
size, the subsequent use of snprintf() may go beyond the given limit
easily. Although the current code doesn't actually overflow the
buffer, it's an incorrect usage.
This patch replaces such snprintf() calls with a safer version,
scnprintf().
Also this fixes the incorrect argument of the buffer limit size passed
to snprintf(), too. The size has to be decremented for the remaining
length.

When EC supports FIFO, each IIO device registers a callback, to put
samples in the buffer when they arrives from the FIFO.
When no FIFO, the user space app needs to call trigger_new, or better

The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.
For the predisable hook, the disable code should occur before detaching
the poll func, and for the postenable hook, the poll func should be
attached before the enable code.
This change moves the postenable/predisable hooks into the correct
positions.

The chip is configured in 24 bit mode. The values read from
it must always be treated as is. This fixes the issue by
replacing the previous 16 bits value by a 24 bits buffer.
This changes affects the value output by previous version of
the driver, since the least significant byte was missing.
The upper half of 16 bit values previously output are now
the upper half of a 24 bit value.

The look-up-table for currens to lux is simply specifying
all currents from 5..47 mA, if we add some values for 0..5
we can just select the index for the lux value in an array
from the mA value. Use clamp() to get the value in the
range of values in the array.

Vishay has published a new version of "Designing the VCNL4200 Into an
Application" application note in October 2019. The new version specifies
that there is +-20% of part to part tolerance. Although the application
note is related to vcnl4200, according to support the vcnl4040's "ASIC
is quite similar to that one for the VCNL4200".
So update the sampling periods (and comment), including the correct
sampling period for proximity. Both sampling periods are lower. Users
relying on the blocking behaviour of reading will get proximity
measurements much earlier.

Vishay has published a new version of "Designing the VCNL4200 Into an
Application" application note in October 2019. The new version specifies
that there is +-20% of part to part tolerance. This explains the drift
seen during experiments. The proximity pulse width is also changed from
32us to 30us. According to the support, the tolerance also applies to
ambient light.
So update the sampling periods. As the reading is blocking, current
users may notice slightly longer response time.

This driver handles two different Sharp sensors that have been
proposed for merging to the mainline kernel over the years, and
already has a limited proximity-only driver in the input
subsystem.
These components are completely different from the confusingly
similarly named Sharp GP2AP020A00F, for which we have a driver
in drivers/iio/light/gp2ap020a00f.c
The two components GP2AP002A00F and GP2AP002S00F are
distinctively different but similar: they share the same set of
registers but differ slightly in the I2C protocol.
Instead of the approach by the previous input driver, we create
a combined IIO proximity and light sensor driver.
The plan is to merge this driver and delete the input driver.
The pieces for the driver are picked all over the place after
researching and grepping through a few different vendor trees
and driver submissions.
We merge it under the light sensors because:
- It has similarities with the Capella CM3605 light sensor and
proximity driver which is there.
- It is related to the GP2AP020A00F driver which is also there.
This driver was tested with the Samsung GT-S7710 mobile phone
which has the GP2AP002S00F proximity sensor mounted.
The suspend/resume cycle will disable the interrupt from the
sensor. If someone would desire to use this interrupt for
wakeup, the driver will need modifications.

This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern
#include <linux/mfd/cros_ec.h>
#include <linux/platform_data/cros_ec_proto.h>
for a single include
#include <linux/platform_data/cros_ec_proto.h>

Merge tag 'tag-chrome-platform-for-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/chrome-platform/linux
Pull chrome platform changes from Benson Leung:
"CrOS EC / MFD / IIO:
- Contains tag-ib-chrome-mfd-iio-input-5.5, which is the first part
of a series from Gwendal to refactor sensor code between MFD, CrOS
EC, iio and input in order to add a new sensorhub driver and FIFO
processing
Wilco EC:
- Add support for Dell's USB PowerShare policy control, keyboard
backlight LED driver, and a new test_event file.
- Fixes use after free in wilco_ec's telemetry driver.
Misc:
- bugfix in cros_usbpd_logger (missing destroy workqueue)"
* tag 'tag-chrome-platform-for-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/chrome-platform/linux:
platform/chrome: wilco_ec: fix use after free issue
platform/chrome: cros_ec: Add Kconfig default for cros-ec-sensorhub
Revert "Input: cros_ec_keyb: mask out extra flags in event_type"
Revert "Input: cros_ec_keyb - add back missing mask for event_type"
platform/chrome: cros_ec: handle MKBP more events flag
platform/chrome: cros_ec: Do not attempt to register a non-positive IRQ number
platform/chrome: cros-ec: Record event timestamp in the hard irq
mfd / platform / iio: cros_ec: Register sensor through sensorhub
iio / platform: cros_ec: Add cros-ec-sensorhub driver
mfd / platform: cros_ec: Add sensor_count and make check_features public
platform/chrome: cros_ec: Put docs with the code
platform/chrome: cros_usbpd_logger: add missed destroy_workqueue in remove
platform/chrome: cros_ec: Fix Kconfig indentation
platform/chrome: wilco_ec: Add keyboard backlight LED support
platform/chrome: wilco_ec: Add charging config driver
platform/chrome: wilco_ec: Add Dell's USB PowerShare Policy control
platform/chrome: wilco_ec: Add debugfs test_event file
Remove the duplicated code in MFD, since MFD just registers cros-ec-sensorhub
if at least one sensor is present.
Change IIO cros-ec driver to get the pointer to the cros-ec-dev through
cros-ec-sensorhub.

veml6030 is an ambient light sensor from Vishay semiconductors.
It has 16-bit resolution, supports both ambient light measurement
and white channel which is more responsive to wider wavelength
spectrum. It has flexible power saving, integration time and
gain options. Communication with host is over I2C.

Third version with the adis rework set dropped as better to just have
a fresh version of that at some future date.
The usual mixed backs of new device support being added to drivers,
long term reworks continuing and little per driver cleanups and
features.
Also a few trivial counter subsystem tidy ups on behalf of William.
Core new feature
* Device label support. A long requested feature no one got around to
implementing before. Allows DT based provision of a 'label' that
identifies a device uniquely within a system. This differs from existing
'name' which is meant to be the part number.
New device support
* ingenic-adc
- Support for the JZ4770 SoC ADC including bindings.
* inv_mpu6050
- Add support for magnetometer in MPU925x parts.
Fiddly to do as this is actually a separate device sitting inside the
package, but with the master device being able to schedule reads etc.
Will only run if the auxiliary bus is not in use for any other devices.
Features
* ad7192
- Userspace calibration controls to do zero and full scale.
* st_lsm6dsx
- Enable latched interrupts by default for sensors events with related clear.
- Motion events and related wakeup source. This needed quite a bit of
refactoring as well.
Cleanups and minor features
* ad7192
- sysfs ABI docs
* ad7949
- Remove code to readback configuration word as driver never actually enabled
it.
- Fix incorrect xfer length. Not actually known to cause problems other
than wasted bus usage.
* adis16080
- Replace core mlock usage with local lock with more appropriate scope.
* adis16130
- Remove pointless mlock usage.
* adis16240
- Remove include of gpio.h as no gpio usage.
* atlas-ph-sensor
- Improve logical ordering of buffer predisable / postenable functions.

When an end-of-conversion interrupt is received after performing a
single-shot reading of the light sensor, the driver was waking up the
result ready queue before checking opt->ok_to_ignore_lock to determine
if it should unlock the mutex. The problem occurred in the case where
the other thread woke up and changed the value of opt->ok_to_ignore_lock
to false prior to the interrupt thread performing its read of the
variable. In this case, the mutex would be unlocked twice.

The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.
For the predisable hook, the disable code should occur before detaching
the poll func, and for the postenable hook, the poll func should be
attached before the enable code.
The driver was slightly reworked. The preenable hook was moved to the
postenable, to add some symmetry to the postenable/predisable part.

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

Use devm_add_action_or_reset to call tsl2772_chip_off

This also fixes the issue that the chip is turned off
before the device is unregistered.
Not marked for stable as fairly hard to hit the bug and
this is in the middle of a set making other cleanups
to the driver. Hence will probably need explicit backporting.

Embedded controller return minimum and maximum frequencies, unfortunately
we have no way to know the step for all available frequencies.
Even if not complete, we can return a list of known values using the
standard read_avail callback (IIO_CHAN_INFO_SAMP_FREQ) to provide them to
userland.
Now cros_ec_* sensors provides frequencies values in sysfs like this:
"0 min max". 0 is always true to disable the sensor.
Default frequencies are provided for earlier protocol.

A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.
New Device Support
* adf4371
- New driver + bindings.
- Support the adf4372 PLL. Mostly ID and bindings.
* ad8366 (note includes rework of driver needed to allow support for these).
- Support the ADL5240 variable gain amplifier (VGA).
- Support the ADA4961 digital gain amplifier (DGA).
* dps310
- New driver, in several parts from different authors for this temp
and pressure sensor.
- Includes errata workaround for a temperature reading issue.
* stk3310
- Support the stk3335, mostly ID.
Features and cleanups
* core
- drop error handling on debugfs registration.
- harden by making sure we don't overrun iio_chan_info_postfix.
* docs
- convert remaining docs to rst. At somepoint we'll fit these few
into the main IIO docs.
- improve sampling_frequency_available docs but explaining the
range form.
* ad_sigma_delta
- Drop a pointless goto.
* ad2s1210
- Drop pointless platform data null check seeing as we don't actually
use platform data anymore.
* ad7124
- Relax limitation on channel numbers to allow pseudo different channels.
- Support control of whether the input is buffered via DT.
- Use dynamic allocation for channel configuration to make it easier
to support new devices.
- YAML binding conversion.
* ad7150
- Comment tidy up.
- Consistent and simple if (ret) handling of i2c errors.
- FIELD_GET and GENMASK.
- Ternary rather than !!(condition) for readability.
- Use macros to avoid repetition of channel definitions.
* ad7606
- Add software channel config (rather that pin controlled)
- Refactor to simplify addition of new part in future.
* ad7746
- of_deivce_id table.
* ad7780
- MAINTAINERS entry
- YAML DT bindings.
* ad8366
- Stop using core mlock in favour of well scoped local lock.
- SPDX + copyright date update.
* ad9834
- of_device_id table
* adf4371
- Add support for output stage muting before lock on has occured.
* adis library
- MAINTAINERS entry to reflect that this now Alexandru's problem ;)
* adis162xx:
- Fix a slightly incorrect set of comments and print statements on
minimum supported voltage.
* adis16203
- of_device_id table.
* adis16240
- Add of_device_id table (in two parts as first patch only used it for
MODULE_DEVICE_TABLE.)
* adt7316-spi
- of_device_id table
* adxl372
- YAML DT binding conversion.
- Cleanup use of buffer callback functions (precursor to core rework).
* bh1710
- Simplify getting the i2c adapter from the client.
* dht11
- Mote to newer GPIO consumer interface.
* kxcjk-1013.c
- Add binding for sensor in display of some ultrabooks after userspace
tools updated for it not be a problem to report two similar sensors.

- white space
- define instead of variable for clock frequency that is fixed.
- drop pointless error message.
* messon_saradc

- Tidy up ordering in various buffer related callbacks. This is
part of a long running effort to simplify the core code.
* stm32-dfsdm:

- Add fast mode support which allows more flexible filter choices.
- Add a comment on the reason for a 16 bit record when technically
not 'required'.
* st_lsm6dsx
- Embed device name in the sensor_settings struct as i3c doesn't
have a convenient name field to use for this.

The MAX44009 is a low-power ambient light sensor from Maxim
Integrated. It differs from the MAX44000 in that it doesn't have
proximity sensing and that it requires far less current (1 micro-amp
vs 5 micro-amps). The register mapping and feature set between the
two are different enough to require a new driver for the MAX44009.
Developed and tested with a BeagleBone Black and UDOO Neo (i.MX6SX)
Supported features:
* Reading lux (processed value)
* Rising and falling illuminance threshold
events
* Configuring integration time

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

Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.
When merging with your tree, there will be 2 merge conflicts, both files
will be simple to resolve, just delete them :)

Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.
Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

VCNL4200 is an integrated long distance (up to 1500mm) proximity and
ambient light sensor.
The support is very basic. There is no configuration of proximity and
ambient light sensing yet. Only the reading of both measured values is
done.
The reading of ambient light and proximity values is blocking. If you
request a new value too early, the driver waits for new value to be
ready.

Also happened was a lot of IIO driver activity, and the typec USB code

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

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.

- fix incorrect data rate setting update when capture in progress,
- fix wrong scale information for the ADS1115,
- make conversions work when CONFIG_PM is not set,

i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with

Set up and use triggered buffer if there is irq defined for device in
device tree. Trigger producer triggers from rpr0521 drdy interrupt line.
Trigger consumer reads rpr0521 data to scan buffer.
Depends on previous commits of _scale and _offset.

The integration time is controlled by the ATIME register only. However,
this register is written by i2c_smbus_write_word_data() in write_raw().
We actually don't need to write a subsequent register. So just use
i2c_smbus_write_byte_data() instead.

The TSL2563 driver provides three iio channels, two of which are raw ADC
channels (channel 0 and channel 1) in the device and the remaining one
is calculated by the two. The ADC channel 0 only supports programmable
interrupt with threshold settings and this driver supports the event but
the generated event code does not contain the corresponding iio channel
type.
This is going to change userspace ABI. Hopefully fixing this to be
what it should always have been won't break any userspace code.

offset value, output values will be (measured_raw - offset_value). Output

Refactor _set_power_state(), _resume() and _suspend().
Enable measurement only when needed, not in _init(). System can suspend
during measurement and measurement is continued on resume.
Pm turns off measurement when both ps and als measurements are disabled for

Set sensor measurement off after probe fail in pm_runtime_set_active() or
iio_device_register(). Without this change sensor measurement stays on
even though probe fails on these calls.
This is maybe rare case, but causes constant power drain without any
benefits when it happens. Power drain is 20-500uA, typically 180uA.

The register mapping for the IIO driver for the Liteon Light and Proximity
sensor LTR501 interrupt mode is interchanged (ALS/PS).
There is a register called INTERRUPT register (address 0x8F)
Bit 0 represents PS measurement trigger.
Bit 1 represents ALS measurement trigger.
This two bit fields are interchanged within the driver.

isl29030 is basically the same chip. The only difference
is the chip's first pin. For isl29028 its named ADDR0 and
can be used to change the chip's i2c address. For isl29030
on the other hand that pin is named Ials and is an analog
current output proportional to ALS/IR. This change is
irrelevant for the Linux driver.
This has been tested on Motorola Droid 4.
