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. * tag 'iio-for-5.3b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (68 commits) iio: iio-utils: Fix possible incorrect mask calculation iio: frequency: adf4371: Add support for output stage mute dt-bindings: iio: frequency: Add ADF4372 PLL documentation iio: frequency: adf4371: Add support for ADF4372 PLL dt-bindings: iio: adc: Add buffered input property Convert AD7124 bindings documentation to YAML format. iio: adc: ad7124: Shift to dynamic allocation for channel configuration iio: adc: ad7124: Add buffered input support iio: adc: ad7124: Remove input number limitation MAINTAINERS: add ADIS IMU driver library entry iio: adis162xx: fix low-power docs & reports counter/ftm-quaddec: Add missing '>' in MODULE_AUTHOR iio: core: no need to check return value of debugfs_create functions docs: iio: convert to ReST iio: adc: stm32-adc: add missing vdda-supply dt-bindings: iio: adc: stm32: add missing vdda supply iio: adc: stm32-dfsdm: add comment for 16 bits record iio: adc: stm32-dfsdm: add fast mode support iio: adc: stm32-dfsdm: manage data resolution in trigger mode iio: adc: stm32-dfsdm: fix data type ...
| * iio: iio-utils: Fix possible incorrect mask calculationBastien Nocera2019-06-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some machines, iio-sensor-proxy was returning all 0's for IIO sensor values. It turns out that the bits_used for this sensor is 32, which makes the mask calculation: *mask = (1 << 32) - 1; If the compiler interprets the 1 literals as 32-bit ints, it generates undefined behavior depending on compiler version and optimization level. On my system, it optimizes out the shift, so the mask value becomes *mask = (1) - 1; With a mask value of 0, iio-sensor-proxy will always return 0 for every axis. Avoid incorrect 0 values caused by compiler optimization.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, num_loops is unsigned, but it's set by strtoll, which returns a (signed) long long int. This could lead to overflow, and it also makes the check "num_loops < 0" always be false, since num_loops is unsigned. Setting num_loops to -1 to loop forever is almost working because num_loops is getting set to a very high number, but it's technically still incorrect. Fix this issue by making num_loops signed. This also fixes an error found by Smatch.

|/ | | | | | | | | | | | | | | | | | | | | Measuring particulate matter in ug / m3 (micro-grams per cubic meter) is de facto standard. Existing air quality sensors usually follow this convention and are capable of returning measurements using this unit. IIO currently does not offer suitable channel type for this type of measurements hence this patch adds this. In addition, extra modifiers are introduced used for distinguishing between fine pm1, pm2p5 and coarse pm4, pm10 particle measurements, i.e IIO_MOD_PM1, IIO_MOD_PM25 and IIO_MOD_PM4, IIO_MOD_PM10. pmX consists of particles with aerodynamic diameter less or equal to X micrometers.

* tools: iio: iio_generic_buffer: allow continuous loopingMartin Kelly2018-05-201-5/+5
| | | | | | | | | | | | | | | Sometimes it's useful to stream samples forever, such as when stress-testing a driver overnight to check for memory leaks or other issues. When the program receives a signal, it will gracefully cleanup, so it is still safe to terminate at any time. Add support for specifying a negative -c option, meaning that we should loop forever. To do so, we need to use a long long (instead of just long) for num_loops so that current code specifying num_loops greater than UNSIGNED_LONG_MAX doesn't break.

* tools: fix cross-compile var clobberingMartin Kelly2018-02-211-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently a number of Makefiles break when used with toolchains that pass extra flags in CC and other cross-compile related variables (such as --sysroot). Thus we get this error when we use a toolchain that puts --sysroot in the CC var: ~/src/linux/tools$ make iio [snip] iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory #include <unistd.h> ^~~~~~~~~~ This occurs because we clobber several env vars related to cross-compiling with lines like this: CC = $(CROSS_COMPILE)gcc Although this will point to a valid cross-compiler, we lose any extra flags that might exist in the CC variable, which can break toolchains that rely on them (for example, those that use --sysroot). This easily shows up using a Yocto SDK: $ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi $ echo $CC arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a8 --sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi $ echo $CROSS_COMPILE arm-poky-linux-gnueabi- $ echo ${CROSS_COMPILE}gcc krm-poky-linux-gnueabi-gcc Although arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the --sysroot and other flags that enable us to find the right libraries to link against, so we can't find unistd.h and other libraries and headers. Normally with the --sysroot flag we would find unistd.h in the sdk directory in the sysroot: $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h' [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not already set, and it compiles correctly with the above toolchain. So, generalize the logic that perf uses in the common Makefile and remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile. Note that this patch does not fix cross-compile for all the tools (some have other bugs), but it does fix it for all except usb and acpi, which still have other unrelated issues. I tested both with and without the patch on native and cross-build and there appear to be no regressions.

* License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

New device support * ad8801 dac - new driver supporting ad8801 and ad8803 DACs. * adc12138 - new driver supporting TI adc12130/adc12132 and adc12138 ADCs. * ltc2485 adc - new driver * mxc6255 - add support for the mxc6225 part name and fixup the ID check so it works. * vz89x VOC sensor - add support for the vz89te part which drops the voc_short channel and adds CRCs compared to other supported parts. New features * core - immutable triggers. These effectively grant exclusive control over a trigger. The typical usecase is a device representing an analog part (perhaps a MUX) that needs to control the sampling of a downstream ADC. - resource managed trigger registration and triggered_buffer_init. - iio_push_event now protected against case of the event interface registration not having yet occured. Only matters if an interrupt can occur during this window - might happen on shared interrupt lines. - helper to let a driver query if the trigger it is using is provided by itself (using the convention of both device and trigger having the same parent). * tools - iio-utils. Used channel modifier scaling in preference to generic scaling when both exist. * at91-adc - Add support for touchscreen switches closure time needed by some newer parts. * stx104 - support the ADC channels on this ADC/DAC board. As these are the primary feature of the board also move the driver to the iio/adc directory. * sx9500 - device tree bindings. Cleanups / Fixes * ad5755 - fix an off-by-one on devnr limit check (introduced earlier this cycle) * ad7266 - drop NULL check on devm_regulator_get_optional as it can't return NULL. * ak8974 - avoid an unused functional warning due to rework in PM core code. - remove .owner field setting as done by i2c_core. * ina2xx - clear out a left over debug field from chip global data. * hid-sensors - avoid an unused functional warning due to rework in PM core code. * maxim-thermocouple - fix non static symbol warnings. * ms5611 - fetch and enable regulators unconditionally when they aren't optional. * sca3000 - whitespace cleanup. * st_sensors - fetch and enable regulators unconditionally rather than having them supported as optional regulators (missunderstanding on my part amongst others a while back) - followup to previous patch fixes error checking on the regulators. - mark symbols static where possible. - use the 'is it my trigger' help function. This prevents the odd case of another device triggering from the st-sensors trigger whilst the st-sensors trigger is itself not using it but rather using say an hrtimer. * ti-ads1015 - add missing of_node_put. * vz89x - rework to all support of new devices. - prevent reading of a corrupted buffer. - fixup a return value of 0/1 in a bool returning function. Address updates - Vlad Dogaru email address change.
| * iio: iio-utils: use channel modifier scaling if it existsMatt Ranostay2016-08-291-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now there are channel modifiers with their own scaling those should be used when possible over the generic channel type scaling. Examples are of IIO_TEMP channel having a generic scaling value, and another having IIO_MOD_TEMP_AMBIENT modifier with another scaling value. Previously the first scaling value for a channel type would be applied to all channels of like type in iio_generic_buffer Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| | | | | | | | | | | | | | | | | | Currently if generic_buffer is invoked without first enabling any channels in scan_elements/*_en, it will fail unable to enable the buffer because bytes_per_datum inside the kernel will be zero if no channels are available. It is implied that the user of the program should enable channels manually or with a script before executing generic_buffer. Be more helpful by stopping execution if no enabled channels can be found, and print a helptext that will tell you what is wrong and what needs to be done.
