2020-02-14iio: srf04: add power management featureAndreas Klinger
Add suspend and resume operations for being used by optional power management. The suspend function is switching off an GPIO which can be used by the hardware to switch power off. The resume function is switching the GPIO on and sleeps an adjustable time to give the device a chance to be up and running. If activated the driver gets into autosuspend after some time of inactivity.

2019-12-01iio: ping: add parallax ping sensorsAndreas Klinger
Add support for parallax ping and laser ping sensors with just one pin for trigger and echo signal. This driver is based on srf04. In contrast to it it's necessary to change direction of the pin and to request the irq just for the period when the echo is rising and falling. Because this adds a lot of cases there is this individual driver for handling this type of sensors. Add a new configuration variable CONFIG_PING to Kconfig and Makefile. Julia reported an issue with failing to unlock a mutex in some error paths.

positions The iio_triggered_buffer_predisable() should be called last, to detach the poll func after the devices has been suspended. This change re-organizes things a bit so that the postenable & predisable are symmetrical. It also converts the preenable() to a postenable().

2019-04-04iio: proximity: as3935: fix use-after-free on device removeSven Van Asbroeck
This driver's probe() uses a mix of devm_ and non-devm_ functions. This means that the remove order will not be the exact opposite of the probe order. Remove order: 1. remove() executes: iio_device_unregister iio_triggered_buffer_cleanup iio_trigger_unregister (A) 2. core frees devm resources in reverse order: free_irq iio_trigger_free iio_device_free In (A) the trigger has been unregistered, but the irq handler is still registered and active, so the trigger may still be touched via interrupt -> as3935_event_work. This is a potential use-after-unregister. Given that the delayed work is never canceled explicitly, it may run even after iio_device_free. This is a potential use-after-free. Solution: convert all probe functions to their devm_ equivalents. Add a devm callback, called by the core on remove right after irq_free, which explicitly cancels the delayed work. This will guarantee that all resources are freed in the correct order. As an added bonus, some boilerplate code can be removed.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
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.)

2017-09-25iio: proximity: as3935: noise detection + threshold changesMatt Ranostay
Most applications are too noisy to allow the default noise and watchdog settings, and thus need to be configurable via DT properties. Also default settings to POR defaults on a reset, and register distuber interrupts as noise since it prevents proper usage.

2017-08-18iio: srf08: add sensor type srf10Andreas Klinger
Ultrasonic sensor srf10 is quite similar to srf08 and now also supported by the driver as device tree compatible string. It was necessary to prepare the source for supplementary sensors. This is done by enum srf08_sensor_type. The most significiant difference between srf08 and srf10 is another range and values of register gain (in the driver it's call sensitivity). Therefore the array of it is extended and dependent of the sensor type. Signed-off-by: Andreas Klinger <ak@it-klinger.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of IIO new device support, features and cleanups for the 4.13 cycle. A few reverts here. One was a general failure to notice a device was already supported by another driver. The second is due to a review comment pointing out that the original patch was a bad idea and would break existing systems. Reverts * bma180 - Revert addition of support for the BMA250E it is already supported by the bmc150-accel and better supported at that. Oops. * hi8435 - The fix for cleanup of the reset gpio stuff isn't a good way to go. It breaks systems where an inverting level convertor is used. The right fix is to make the original devicetree correct - even if it involves patching the devicetree in kernel. New Device Support * stm32-adc - STM32H7 support and bindings. Features * core - add a hardware triggered operating mode for systems in which the actual trigger is never seen by the kernel. This is typically only used when a device 'can' use other triggers, but if a particular magic one is enabled the interrupt is effectively handled in hardware and we never see it. * st-lsm6dsx - support active low interrupts. * stm32-adc - Make the core adc clock optional as not all hardware supported requires it. - Make the bus clock optional in the per instance driver as it may be shared by all instances of the ADC and is handled by the core. - Rework to have a data structure representing the device type specific elements. * stm32-trigger (and counter) - Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate. - Add an attribute to configure device modes for quadrature counting etc. Clean ups and minor fixes * IIO core. - use __sysfs_match_string() helper rather than open coding the same. * ad7791 - use sysfs_match_string() helper rather than open coding the same. * aspeed-adc - handle return value of clk_prepare_enable * cpcap - Fix default register values and ensure the battery thermistor is enabled correctly. - Fix the reported die temperature where we can - docs are lacking. - Remove the hung interrupt quirk as no longer happens due to fix in the mfd driver. * hi8435 - Remove &s from hi8435_info definition as unneeded and inconsistent. * hid-sensor-trgger - Add kconfig depends on IIO_BUFFER (fixes patch in previous series) * ina2xx - Make the use of iio_info_mask* elements consistent for all channels. This doesn't have any visible effect, but acts as clear documentation of which channels various resulting attributes apply to. * lpc32xx - handle the return value of clk_prepare_enable. * meson-saradc - NULL instead of 0 for pointer. * mma9551 - use NULL for GPIO connection ID to aid implementation fo ACPI support. Here the connection ID doesn't actually tell us anything and it is much easier to deal with the driver if it's not there. * mpu6050 - Fix lock issues through use of a local mux. - Replace sprintf with scnprintf as appropriate. - Check whoami against all known values. This allows for a small number of boards where we are really fishing for the part not being present at all. It is unfortunately common to have undescribed changes to use newer chips. We paper over this but just emitting a warning for those cases as long as we know about. * mxs-lradc - Fix some non static warnings. * rcar-adc - Part of making the naming for this part consistent across the kernel. * st_accel - drop some spi_device_id entries for variants with no SPI support * st_magn - drop some spi_device_id entries for variants with no SPI support. * sx9500 - Use devm_gpiod_get instead of indexed value with an index of 0 on all occasions. * twl4030 - Drop unused twl4030_get_madc_conversion as callers removed now throughout kernel. - Unexport twl4030_madc_conversion() as no used only within this driver. - Drop twl4030_madc_user_params as not used now. - Drop twl4030_madc_request.func_cb as not used now. - Fold the twl4030-madc.h header into the driver as no longer used anywhere else in the kernel. * xilinx - Handle the return value of clk_prepare_enable

As these are rather late in the cycle, they may sneak over into 4.12.

Numeric values were being passed as characters presumably leading to garbage from the userspace interface. * as3935 - the write data macro was wrong so fix it. * bmp280 - incorrect handling of negative values as being unsigned broke humidity calculation. * hid-sensor - Restore the poll and hysteresis values after resume as some hardware doesn't do it. * stm32-trigger - buglet in reading the sampling frequency
