* iio: st_accel: use ACPI orientation dataDaniel Drake2019-02-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Platform-specific ST accelerometer mount matrix information can be provided by returning a package of 6 integers from the ACPI _ONT method. This has been seen on Acer products such as Veriton Z4860G, Z6860G and A890, which include a ST SMO8840 sensor. We have also confirmed experimentally that the Windows driver uses such information. The _ONT data format was explained by a ST vendor contact. However, strangely enough, the _ONT transformations must be applied after first applying another mount matrix which we determined experimentally. ST have not commented on why this is the case, but we imagine that perhaps earlier devices (before _ONT was introduced) required this translation and hence it became 'standard.' Interpret the _ONT data and export the equivalent mount matrix to userspace. If no _ONT data is present, no mount matrix is exported.

It was delayed as I wanted to make sure the final driver deletions did not cause any major merge issues, and all now looks good. There are a lot of patches here, just over 1000. The diffstat summary shows the major changes here: 1007 files changed, 16828 insertions(+), 227770 deletions(-) Because of this, we might be close to shrinking the overall kernel source code size for two releases in a row. There was loads of work in this release cycle, primarily: - tons of ks7010 driver cleanups - lots of mt7621 driver fixes and cleanups - most driver cleanups - wilc1000 fixes and cleanups - lots and lots of IIO driver cleanups and new additions - debugfs cleanups for all staging drivers - lots of other staging driver cleanups and fixes, the shortlog has the full details. but the big user-visable things here are the removal of 3 chunks of code: - ncpfs and ipx were removed on schedule, no one has cared about this code since it moved to staging last year, and if it needs to come back, it can be reverted. - lustre file system is removed. I've ranted at the lustre developers about once a year for the past 5 years, with no real forward progress at all to clean things up and get the code into the "real" part of the kernel. Given that the lustre developers continue to work on an external tree and try to port those changes to the in-kernel tree every once in a while, this whole thing really really is not working out at all. So I'm deleting it so that the developers can spend the time working in their out-of-tree location and get things cleaned up properly to get merged into the tree correctly at a later date. Because of these file removals, you will have merge issues on some of these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the atomisp driver). Just delete those files, it's a simple merge :) All of this has been in linux-next for a while with no reported problems" * tag 'staging-4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (1011 commits) staging: ipx: delete it from the tree ncpfs: remove uapi .h files ncpfs: remove Documentation ncpfs: remove compat functionality staging: ncpfs: delete it staging: lustre: delete the filesystem from the tree. staging: vc04_services: no need to save the log debufs dentries staging: vc04_services: vchiq_debugfs_log_entry can be a void * staging: vc04_services: remove struct vchiq_debugfs_info staging: vc04_services: move client dbg directory into static variable staging: vc04_services: remove odd vchiq_debugfs_top() wrapper staging: vc04_services: no need to check debugfs return values staging: mt7621-gpio: reorder includes alphabetically staging: mt7621-gpio: change gc_map to don't use pointers staging: mt7621-gpio: use GPIOF_DIR_OUT and GPIOF_DIR_IN macros instead of custom values staging: mt7621-gpio: change 'to_mediatek_gpio' to make just a one line return staging: mt7621-gpio: dt-bindings: update documentation for #interrupt-cells property staging: mt7621-gpio: update #interrupt-cells for the gpio node staging: mt7621-gpio: dt-bindings: complete documentation for the gpio staging: mt7621-dts: add missing properties to gpio node ...

* | iio:buffer: make length types match kfifo typesMartin Kelly2018-03-301-3/+3
|/ | | | | | | | | | | | | | | | | 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.

* / iio: stm32: fix adc/trigger link errorArnd Bergmann2017-12-021-1/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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).

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.

Without it no channels work. * axp288 - Revert a patch that dropped some bogus register mods. No one is entirely sure why but it breaks charging on some devices. - Fix GPADC pin read returning 0. Turns out a small sleep is needed. * bmc150 - Make sure device is restored to normal state after suspend / resume cycle. Otherwise, simple sysfs reads are broken. * tsl2563 - fix wrong event code. * st-accel - add spi 3-wire support. Needed to fix the lsm303agr accelerometer which only had 3 wires in all cases. Side effect is to enable optional 3-wire support for other devices. * st-pressure - disable multiread by default for LPS22HB (only effects SPI) * sun4i-gpadc-iio - fix unbalanced irq enable / disable * vf610 - Fix VALT slection for REFSEL bits - ensures we are using the right reference pins.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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. - rename H3LIS331DL_DRIVER_NAME to line up with similar entries in driver. * st_gyro - explicit OF table (spi). * st_magn - explicit OF table (spi). - enable multiread for lis3mdl. * st_pressure - explicit OF table (spi). * st_sensors common. - move st_sensors_of_i2c_probe and rename to make it available for spi 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 some newline to the end of logging macros.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move st_sensors_of_i2c_probe() in st_sensors_core and rename it in st_sensors_of_name_probe(). That change is necessary to add device-tree support in spi code otherwise the rest of the autodetection will fail since spi->modalias (and indio_dev->name) will be set using compatible string value that differs from standard sensor name Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
