iio:st_sensors: remove buffer allocation at each buffer enable
This patch is removing the buffer allocation at each buffer enable. We just allocate enough memory in the main structure during probe to cover maximum size needed (that anyway is pretty small) [16bytes].

iio: remove get_irq_data_ready() function pointer and use IRQ number directly

iio:pressure: preenable/postenable/predisable fixup for ST press buffer
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.

iio: make st_sensors drivers use regmap
This patch is meant to replace the i2c/spi transfer functions with regmap. SPI framework requires DMA safe buffers so let's add GFP_DMA flag for memory allocation used by bulk_read functions.

iio: move 3-wire spi initialization to st_sensors_spi
Some devices need to be configured with special bit in order to use spi 3-wire. This was done during device identification phase. Instead, let's move this part as spi specific. Doing this the check_device_support function becomes a simple device id check, so let's rename it.

Second set of IIO device support, features, cleanups and minor fixes for 5.3.
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.
* imx7d
- drop unused variables.
- white space
- define instead of variable for clock frequency that is fixed.
- drop pointless error message.
* messon_saradc
- SPDX
* sps30
- MAINTAINERS entry
- YAML binding conversion.
* st_accel
- Tidy up ordering in various buffer related callbacks. This is
part of a long running effort to simplify the core code.
* stm32-dfsdm:
- Manage the resolution cleanly in triggerd modes.
- 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.
* xilinx-adc
- Relax constraints on supported platforms to reflect that this
can used with FPGAs on PCIe cards and hence many architectures.
* counters/ftm-quaddec
- Fix some formatting io MODULE_AUTHOR
- MAINTAINERS entry
Fixes
* tools
- fix incorrect handling of 32 bit channels.
* sca3000
- Potential endian bug that is unlikely to bite anyone (be64 host
seems unlikely for this old part).
* stm32-adc
- Add vdda-supply. On some boards it needs to be turned on to supply
the ADC. DT bindings included.
* stm32-dfsdm
- Fix output resolution to work with filter orders other than 3.
- Fix output datatype as it's signed and previously claimed not to be.

The cros_ec sensors drivers do not call any sysfs functions or use any sysfs defines, and thus do not need to include linux/sysfs.h. Also, some cros_ec drivers include linux/delay.h and is not used.

iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers
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 statements were needlessly split over 2 lines to improve readability.

- Support AD5685R (was wrongly present as AD5685)
- Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
SPI DACs with various precisions.
- Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
I2C DACs with various percisions and numbers of channels.
* Analog front end rescale driver - New driver.
- Support current sensing usings a shunt resistor.
- Support simple voltage dividers.
- support simple current sense amplifiers.
* TI dac5571
- New driver and device bindings supporting:
dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
dac5573, dac6573 and dac7573
* Meson-adc
- Support for Meson AXG with DT bindings.
* mpu6050
- Support the mpu9255 which only requires additional WHOAMI entry and
compatible string.
* st_lsm6dsx
- Support for lsm330dlc combinded accelerometer and gyro sensors with
DT bindings.
* stm32_adc
- Add support for STM32MP1 with bindings.
Staging graduations
* adis16201 after some excelent cleanup by Himanshu Jha.
* adis16029 after some excelent cleanup by Shreeya Patel.
New features:
* ABI docs
- Add core ABI docs for angle channels.
* inv_mpu6050
- Provide support for the full range of interrupts the device
supports.
* st_accel
- Add SMO8840 ACPI ID seen in the wild on some Lenovo machines.
* stx104
- Provide a multiple gpio get function.
Cleanups / Minor fixes
* core
- Use new nested structure support to improve kernel-doc.
* ad2s1200
- Use be16_to_cpup instead of opencoding.
* ad5686
- Indentation tidy up.
- Switch to SPDX
- Refactor to allow various numbers of channels.
- Refactor to separate core and SPI specific support, prior to
addition of i2c equivalent devices.
* ad7606
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* ad7746
- Replace opencoded byte swapped i2c calls with _swapped variants.
- White space and line break readability improvements.
- Reorder includes and variable declarations where appropriate.
* ad7791
- Changes to the AD ADC library used by this driver took in the
sampling frequency. This lead to be the wrong path being the one
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.

iio:pressure:bmp280: Read calibration data in probe
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.

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.

iio: st_sensors: add register mask for status register
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.

iio: pressure: zpa2326: Remove always-true check which confuses gcc
With gcc 4.1.2:
drivers/iio/pressure/zpa2326.c: In function ‘zpa2326_wait_oneshot_completion’:
drivers/iio/pressure/zpa2326.c:868: warning: ‘ret’ may be used uninitialized in this function
When testing for "timeout < 0", timeout is already guaranteed to be
strict negative, so the branch is always taken, and ret is thus always
initialized. But (some version of) gcc is not smart enough to notice.
Remove the check to fix this.
As there is no other code in between assigning the error codes and
returning them, the error codes can be returned immediately, and the
intermediate variable can be dropped.
Drop the "else" to please checkpatch.

Round one of new device support, features and cleanup for IIO in the 4.15 cycle.
Note there is a misc driver drop in here given we have support
in IIO and the feeling is no one will care.
A large part of this series is a boiler plate removal series avoiding
the need to explicitly provide THIS_MODULE in various locations.
It's very dull but touches all drivers.
New device support
* ad5446
- add ids to support compatible parts DAC081S101, DAC101S101,
DAC121S101.
- add the dac7512 id and drop the misc driver as feeling is no
one is using it (was introduced for a board that is long obsolete)
* mt6577
- add bindings for mt2712 which is fully compatible with other
supported parts.
* st_pressure
- add support for LPS33HW and LPS35HW with bindings (ids mostly).
New features
* ccs811
- Add support for the data ready trigger.
* mma8452
- remove artifical restriction on supporting multiple event types
at the same time.
* tcs3472
- support out of threshold events
Core and tree wide cleanup
* Use macro magic to remove the need to provide THIS_MODULE as part of
struct iio_info or struct iio_trigger_ops. This is similar to
work done in a number of other subsystems (e.g. i2c, spi).
All drivers are fixed and then the fields in these structures are
removed.
This will cause build failures for out of tree drivers and any
new drivers that cross with this work going into the kernel.
Note mostly done with a coccinelle patch, included in the series
on the mailing list but not merged as the fields no longer exist
in the structures so the any hold outs will cause a build failure.
Cleanups
* ads1015
- avoid writing config register when it doesn't change.
- add 10% to conversion wait time as it seems it is sometimes
a little small.
* ade7753
- replace use of core mlock with a local lock. This is part of a
long term effort to make the use of mlock opaque and single
purpose.
* ade7759
- expand the use of buf_lock to cover previous mlock cases. This
is a slightly nicer solution to the same issue as in ade7753.
* cros_ec
- drop an unused variable
* inv_mpu6050
- add a missing break in a switch for consistency - not actual
bug,
- make some local arrays static to save on object code size.
* max5481
- drop manual setting of the spi module owner as handled by the
spi core.
* max5487
- drop manual setting of the spi module owner as handled by the
spi core.
* max9611
- drop explicit setting of the i2c module owner as handled by
the i2c core.
* mcp320x
- speed up reads on single channel devices,
- drop unused of_device_id data elements,
- document the struct mcp320x,
- improve binding docs to reflect restrictions on spi setup and
to make it explicit that the reference regulator is needed.
* mma8452
- symbolic to octal permissions,
- unsigned to unsigned int.
* st_lsm6dsx
- avoid setting odr values multiple times,
- drop config of LIR as it is only ever set to the existing
defaults,
- drop rounding configuration as it only ever matches the defaults.
* ti-ads8688
- drop manual setting of the spi module owner as handled by the
spi core.
* tsl2x7x
- constify the i2c_device_id,
- cleanup limit checks to avoid static checker warnings (and generally
have nicer code).

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.

IIO: BME280: Updates to Humidity readings need ctrl_reg write!
The ctrl_reg register needs to be written after any write to the humidity registers. The value written to the ctrl_reg register does not necessarily need to change, but a write operation must occur. The regmap_update_bits functions will not write to a register if the register value matches the value to be written. This saves unnecessary bus operations. The change in this patch forces a bus write during the chip_config operation by switching to regmap_write_bits. This will fix issues where the Humidity Sensor Oversampling bits are not updated after initialization.
