50892cb292 iio: ad_sigma_delta: Properly handle SPI bus locking vs CS assertion
[ Upstream commit df1d80aee963480c5c2938c64ec0ac3e4a0df2e0 ]

For devices from the SigmaDelta family we need to keep CS low when doing a
conversion, since the device will use the MISO line as a interrupt to
indicate that the conversion is complete.

This is why the driver locks the SPI bus and when the SPI bus is locked
keeps as long as a conversion is going on. The current implementation gets
one small detail wrong though. CS is only de-asserted after the SPI bus is
unlocked. This means it is possible for a different SPI device on the same
bus to send a message which would be wrongfully be addressed to the
SigmaDelta device as well. Make sure that the last SPI transfer that is
done while holding the SPI bus lock de-asserts the CS signal.

30ab9366f7 iio:buffer: make length types match kfifo types
commit c043ec1ca5baae63726aae32abbe003192bc6eec upstream.

Currently, we use int for buffer length and bytes_per_datum. However,
kfifo uses unsigned int for length and size_t for element size. We need
to make sure these matches or we will have bugs related to overflow (in
the range between INT_MAX and UINT_MAX for length, for example).

In addition, set_bytes_per_datum uses size_t while bytes_per_datum is an
int, which would cause bugs for large values of bytes_per_datum.

Change buffer length to use unsigned int and bytes_per_datum to use
size_t.

d1f13dcad5 iio: st_sensors: add register mask for status register
[ Upstream commit e72a060151e5bb673af24993665e270fc4f674a7 ]

Introduce register mask for data-ready status register since
pressure sensors (e.g. LPS22HB) export just two channels
(BIT(0) and BIT(1)) and BIT(2) is marked reserved while in
st_sensors_new_samples_available() value read from status register
is masked using 0x7.
Moreover do not mask status register using active_scan_mask since
now status value is properly masked and if the result is not zero the
interrupt has to be consumed by the driver. This fix an issue on LPS25H
and LPS331AP where channel definition is swapped respect to status
register.
Furthermore that change allows to properly support new devices
(e.g LIS2DW12) that report just ZYXDA (data-ready) field in status register
to figure out if the interrupt has been generated by the device.

c55befc42a iio: stm32: fix adc/trigger link error
commit 6d745ee8b5e81f3a33791e3c854fbbfd6f3e585e upstream.

The ADC driver can trigger on either the timer or the lptim
trigger, but it only uses a Kconfig 'select' statement
to ensure that the first of the two is present. When the lptim
trigger is enabled as a loadable module, and the adc driver
is built-in, we now get a link error:

drivers/iio/adc/stm32-adc.o: In function `stm32_adc_get_trig_extsel':
stm32-adc.c:(.text+0x4e0): undefined reference to `is_stm32_lptim_trigger'

We could use a second 'select' statement and always have both
trigger drivers enabled when the adc driver is, but it seems that
the lptimer trigger was intentionally left optional, so it seems
better to keep it that way.

This adds a hack to use 'IS_REACHABLE()' rather than 'IS_ENABLED()',
which avoids the link error, but instead leads to the lptimer trigger
not being used in the broken configuration. I've added a runtime
warning for this case to help users figure out what they did wrong
if this should ever be done by accident.

a54f83c3f4 iio: support writing processed values to IIO channels
Add a new function to the IIO API which allows consumers to write
processed values to IIO channels.

This is particularly useful for supporting hardware which has
configurable ADC thresholds. A consumer would be able to change an ADC
threshold by providing a processed value instead of calculating a raw
value.

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.

First round of IIO fixes for the 4.14 cycle

Note this includes fixes from recent merge window.  As such the tree
is based on top of a prior staging/staging-next tree.

* iio core
  - return and error for a failed read_reg debugfs call rather than
    eating the error.
* ad7192
  - Use the dedicated reset function in the ad_sigma_delta library
    instead of an spi transfer with the data on the stack which
    could cause problems with DMA.
* ad7793
  - Implement a dedicate reset function in the ad_sigma_delta library
    and use it to correctly reset this part.
* bme280
  - ctrl_reg write must occur after any register writes
  for updates to take effect.
* mcp320x
  - negative voltage readout was broken.
  - Fix an oops on module unload due to spi_set_drvdata not being called
    in probe.
* st_magn
  - Fix the data ready line configuration for the lis3mdl. It is not
    configurable so the st_magn core was assuming it didn't exist
    and so wasn't consuming interrupts resulting in an unhandled
    interrupt.
* stm32-adc
  - off by one error on max channels checking.
* stm32-timer
  - preset should not be buffered - reorganising register writes avoids
  this.
  - fix a corner case in which write preset goes wrong when a timer is
  used first as a trigger then as a counter with preset. Odd case but
  you never know.
* ti-ads1015
  - Fix setting of comparator polarity by fixing bitfield definition.
* twl4030
  - Error path handling fix to cleanup in event of regulator
    registration failure.
  - Disable the vusb3v1 regulator correctly in error handling
  - Don't paper over a regulator enable failure.

The kerneldoc description for the trig_readonly field of struct iio_dev
lacked a colon, leading to this doc build warning:

  ./include/linux/iio/iio.h:603: warning: No description found for parameter 'trig_readonly'

A similar issue for iio_trigger_set_immutable() in trigger.h yielded:

  ./include/linux/iio/trigger.h:151: warning: No description found for parameter 'indio_dev'

First round of IIO new device support, features and cleanups for the 4.14 cycle.

4 completely new drivers in this set and plenty of other stuff.

One ABI change due to a silly mistake a long time back. Hopefully no
one will notice.  It effects the numerical order of consumer device
channels which was the reverse of the obvious.  It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)

New Device Support
* ccs811
  - new driver for the Volatile Organic Compounds (VOC) sensor.
* dln2 adc
  - new driver for the ADC on this flexible usb board.
* EP93xx
  - new driver for this Cirrus logic SoC ADC.
* ltc2471
  - new ADC driver support the ltc2471 and ltc2473
* st_accel
  - add trivial table entries to support H3LIS331DL, LIS331DL, LIS3LV02DL.
* st_gyro
  - add L3GD20H support (again) having fixed the various things that were
    broken in the first try.  Includes devicetree binding.
* stm32 dac
  - add support for the DACs in the STM32F4 series

Features
* Documentation
  - add missing power attribute documentation to the ABI docs.
* at91-sama5d2
  - add hardware trigger and buffered capture support with bindings.
  - suspend and resume functionality.
* bmc150
  - support for the BOSC0200 ACPI device id seen on some tablets.
* hdc100x
  - devicetree bindings
  - document supported devices
  - match table and device ids.
* hts221
  - support active low interrupts (with bindings)
  - open drain mode with bindings.
* htu21
  - OF match table and bindings.
* lsm6dsx
  - open drain mode with bindings
* ltc2497
  - add support for board file based consumer mapping.
* ms5367
  - OF match table and bindings.
* mt7622
  - binding document and OF match table.
  - suspend and resume support.
* rpr0521
  - triggered buffer support.
* tsys01
  - OF match table and bindings.

Cleanups and minor fixes
* core
  - fix ordering of IIO channels to entry numbers when using
    iio_map_array_register rather than reversing them.
  - use the new %pOF format specifier rather than full name for the
    device tree nodes.
* ad7280a
  - fix potential issue with macro argument reuse.
* ad7766
  - drop a pointless NULL value check as it's done in the gpiod code.
* adis16400
  - unsigned -> unsigned int.
* at91 adc
  - make some init data static to reduce code size.
* at91-sama5d2 ADC
  - make some init data static to reduce code size.
* da311
  - make some init data static to reduce code size.
* hid-sensor-rotation
  - drop an unnecessary static.
* hts221
  - refactor the write_with_mask code.
  - move the BDU configuration to probe time as there is no reason for it
    to change.
  - avoid overwriting reserved data during power-down.  This is a fix, but
    the infrastructure need was too invasive to send it to mainline except
    in a merge window.  It's not a regression as it was always wrong.
  - avoid reconfigure the sampling frequency multiple times by just
    doing it in the write_raw function directly.
  - refactor the power_on/off calls into a set_enable.
  - move the dry-enable logic into trig_set_state as that is the only
    place it was used.
* ina219
  - fix polling of ina226 conversion ready flag.
* imx7d
  - add vendor name in kconfig for consistency with similar parts.
* mcp3422
  - Change initial channel to 0 as it feels more logical.
  - Check for some errors in probe.
* meson-saradc
  - add a check of of_match_device return value.
* mpu3050
  - allow open drain for any interrupt type.
* rockchip adc
  - add check on of_match_device return value.
* sca3000
  - drop a trailing whitespace.
* stm32 adc
  - make array stm32h7_adc_ckmodes_spec static.
* stm32 dac
  - fix an error message.
* stm32 timers
  - fix clock name in docs to match reality after changes.
* st_accel
  - explicit OF table (spi).
  - add missing entries to OF table (i2c).
  - rename of_device_id table to drop the part name.
  - adding missing lis3l02dq entry to bindings.

  drivers.
* tsc3472
  - don't write an extra byte when writing the ATIME register.
  - add a link to the datasheet.
* tsl2x7x - continued staging cleanups
  - add of_match_table.
  - drop redundant power_state sysfs attribute.
  - drop wrapper tsl2x7x_i2c_read.
  - clean up i2c calls made in tsl2x7x_als_calibrate.
  - refactor the read and write _event_value callbacks to handle additional
    elements.
  - use usleep_range instead of mdelay.
  - check return value from tsl2x7x_invoke_change.
* zpa2326

Add SPI Serial Interface Mode (SIM) register information
in st_sensor_settings look up table to support devices
(like LSM303AGR accel sensor) that allow just SPI-3wire
communication mode. SIM mode has to be configured before any
other operation since it is not enabled by default and the driver
is not able to read without that configuration

Whilst a fairly substantial patch, the actual logic is simple and it
is better to have the generic fix than a band aid.

93fbe91b55 iio: Add STM32 timer trigger driver
Timers IPs can be used to generate triggers for other IPs like
DAC or ADC.
Each trigger may result of timer internals signals like counter enable,
reset or edge, this configuration could be done through "master_mode"
device attribute.

Since triggers could be used by DAC or ADC their names are defined
in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger
function could be used to check if the trigger is valid or not.

"trgo" trigger have a "sampling_frequency" attribute which allow to configure
timer sampling frequency.

version 8:
- change kernel version from 4.10 to 4.11 in ABI documentation

version 7:
- remove all iio_device related code
- move driver into trigger directory

version 5:
- simplify tables of triggers
- only create an IIO device when needed

version 4:
- get triggers configuration from "reg" in DT
- add tables of triggers
- sampling frequency is enable/disable when writing in trigger
  sampling_frequency attribute
- no more use of interruptions

version 3:
- change compatible to "st,stm32-timer-trigger"
- fix attributes access right
- use string instead of int for master_mode and slave_mode
- document device attributes in sysfs-bus-iio-timer-stm32

version 2:
- keep only one compatible
- use st,input-triggers-names and st,output-triggers-names
  to know which triggers are accepted and/or create by the device

First round of new device support, features and cleanups for IIO in the 4.11 cycle.

It's shaping to be another fairly busy cycle. Lots more on the way!

New device support
* ads7950
  - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954,
  ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs.
* cm3605
  - New driver for this light sensor and proximity sensor  which is an
  analog part with some additional digital controls.
* hx711
  - New driver.

Core new stuff
* Gravity sensor type.  This is a processed datastream in which the device
will try to work out which way is down.
* Split the buffer.h file into two parts. One provides the interface to 'use'
a buffer, the second provides the internals of the buffer functionality as
needed by implementations of buffers.
  - Move documentation inline so as to allow use of private: tag when
  generating documentation.
  - Add some utility functions for the few things that are directly done
  with the buffers.
  - Stop exporting functions that no-one uses outside of the core code.
  - Push docs down by the code in the c file where they should have always
  been.
  - Fix typo in kernel-doc for buffer.
  - push down some includes that were previously happening implicitly.
  - stop enabling the timestamp of the dummy device.

Features and cleanups
* ad5592r
  - ACPI support
* ad5593r
  -ACPI support.
* ad5933
  - Fix a false comment about size of a particular register.
* ad7150
  - replace S_IRUGO | S_IWUSR with 0644.  I'm not that keen on these patches
  in general, but as it was nicely presented I took this one anyway. As a
  general rule will only take these as part of a larger driver cleanup.
  - don't eat an error but rather reutnr it in the write_event_config callback.
* ad7606
  - replace non standard range attibute with _scale
* ade7753
  - use usleep_range for short sleeps
* ade7754
  - use usleep_range for short sleeps
* ade7758
  - use usleep_range for short sleeps
* ade7759
  - use usleep_range for short sleeps
* ade7854
  - use usleep_range for short sleeps
* adis16201
  - fix description
* adis16203
  - fix description
  - fix copyright year
* adis16209
  - fix description
* adt7316
  - Add braces to arms of if else statement (for consistency)
  - Alignment fixes.
* axp288
  - Fix up an issue with accidental overwrites of data.
* bmi160
  - add deivce tables for i2c and spi to support correctly identifying the
  full dt name (including manufacturer).
  - device tree binding.
* bmp280
  - use usleep_range for short sleeps.
* cm3232
  - return error from cm3232_reg_init rather than eating it if the last write
  fails.
* dummy driver
  - remove a semicolor found at end of a function defintition.
* exynos-adc
  - use usleep_range for short sleeps.
* hid-sensor (accel)
  - Add timestamp support.  The hardware can provide timestamps so lets support
  them. If not fall back to timestamps estimated in kernel.
* hid-sensor (light)
  - Add a duplicate ID for the light channels so as to keep existing interface
  whilst also using the more standard IIO interface.
* hts221
  - acpi probing
* imx25-gcq
  - Add a macro call to allow this driver to be automatically loaded.
* isl29028
  - reorganise code to avoid deep nesting of if statements.
  - move chip test and default regs into a function suitable or sharing with
  power management code.
  - tidy up some code alignment.
* lidar-lite-v3
  - introduce compatible strings that make it clear Garmin have consideral
  friends.
* mma8452
  - avoid returning signed value when unsigned is appropriate
* spmi-vadc
  - Update function for generic voltage conversion to take into account that
  different channels on this device should be handled differently.
  - Rework code to allow per channel voltage scaling and support the standard
  options for this hardware.
  - Fixup three minor issues with the above patches for this part. These all
  effect test builds rather than the native builds for the part, but good to
  clean them up anyway.
* st_sensors
  - support device matching from the ACPI DST tables.
  - acpi based probing for accelerometers
  - acpi based probing for pressure sensors
  - Allow pressure sensors to read negative values.
  - Export sampling frequency for lps25h and lps331ap.
  - Add support for the old DT bindings from the period when these deivces
  were often supported through windows.

Docs fixup:
* typo in sysfs-bus-iio

33dd94cb97 iio:buffer.h - split into buffer.h and buffer_impl.h
buffer.h supplies everything needed for devices using buffers.
buffer_impl.h supplies access to the internals as needed to write
a buffer implementation.

This was really motivated by the mess that turned up in the
kernel-doc documentation pulled in by the new sphinx docs.
It made it clear that our logical separations in headers were
generally terrible.  The buffer case was easy to sort out without
greatly effecting drivers so here it is.

263cf5e657 iio:buffer.h Reformat structure comments to be inline.
This should make it easier to see how the structure is split into
public and private parts - reflected in the generated documentation.

Deliberately use /* instead of /** for the private elements to avoid
warnings when kernel-doc script runs.

Nothing outside of indiustrialio-buffer.c should be using this.
Requires a large amount of juggling of functions to avoid a

65e4345c8e iio: accel: st_accel: fix LIS3LV02 reading and scaling
The LIS3LV02 has a special bit that need to be set to get the
read values left aligned. Before this patch we get gibberish
like this:

iio_generic_buffer -a -c10 -n lis3lv02dl_accel
(...)
0.000000 -0.010042 -0.642688 19155832931907
0.000000 -0.010042 -0.642688 19155858751073

Which is because we read a raw value for 1g as 64 which is
the nominal 1024 for 1g shifted 4 bits to the left by being
right-aligned rather than left aligned.

Since all other sensors are left aligned, add some code to
set the special DAS (data alignment setting) bit to 1 so that
the right value is now read like this:

iio_generic_buffer -a -c10 -n lis3lv02dl_accel
(...)
0.000000 -0.147095 -10.120135 24761614364956
-0.029419 -0.176514 -10.120135 24761631624540

The scaling was weird as well: we have a gain of 1000 for 1g
and 3000 for 6g. I don't even remember how I came up with the
old values but they are wrong.

00c5f80c2f iio: inkern: add helpers to query available values from channels
Specifically a helper for reading the available maximum raw value of a
channel and a helper for forwarding read_avail requests for raw values
from one iio driver to an iio channel that is consumed.

These rather specific helpers are in turn built with generic helpers
making it easy to build more helpers for available values as needed.

5123960007 iio:core: add a callback to allow drivers to provide _available attributes
A large number of attributes can only take a limited range of values.
Currently in IIO this is handled by directly registering additional
*_available attributes thus providing this information to userspace.

It is desirable to provide this information via the core for much the same
reason this was done for the actual channel information attributes in the
first place.  If it isn't there, then it can only really be accessed from
userspace.  Other in kernel IIO consumers have no access to what valid
parameters are.

Two forms are currently supported:
* list of values in one particular IIO_VAL_* format.
	e.g. 1.300000 1.500000 1.730000
* range specification with a step size:
	e.g. [1.000000 0.500000 2.500000]
	equivalent to 1.000000 1.5000000 2.000000 2.500000

An addition set of masks are used to allow different sharing rules for the
*_available attributes generated.

This allows for example:

in_accel_x_offset
in_accel_y_offset
in_accel_offset_available.

We could have gone with having a specification for each and every
info_mask element but that would have meant changing the existing userspace
ABI.  This approach does not.

29157c6d60 iio: dac: mcp4725: support voltage reference selection
MCP47x6 chip supports selection of a voltage reference (VDD, VREF buffered
or unbuffered). MCP4725 doesn't have this feature thus the eventual setting
is ignored and user is warned.

The setting is stored only in the volatile memory of the chip. You need to
manually store it to the EEPROM of the chip via 'store_eeprom' sysfs entry.
