Staging/IIO patches for 4.15-rc1
Here is the "big" staging and IIO driver update for 4.15-rc1. Lots and lots of little changes, almost all minor code cleanups as the Outreachy application process happened during this development cycle. Also happened was a lot of IIO driver activity, and the typec USB code moving out of staging to drivers/usb (same commits are in the USB tree on a persistent branch to not cause merge issues.) Overall, it's a wash, I think we added a few hundred more lines than removed, but really only a few thousand were modified at all. All of these have been in linux-next for a while. There might be a merge issue with Al's vfs tree in the pi433 driver (take his changes, they are always better), and the media tree with some of the odd atomisp cleanups (take the media tree's version).

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.

Second set of IIO new drivers, functionality and cleanups for the 4.5 cycle.
The big one here is the configfs support which has been a long time in the works but should allow for cleaner ways to do instantiation of those elements of IIO that aren't directly connected to specific hardware. Lots of cool new stuff we can use this for in the works! New core stuff (basically all configfs support related) * Configfs support - Core support (was waiting for a configfs patch that went in around 4.4rc2) - A little fixlet to add a configfs.h to contain a reference to the configfs_subsystem structure. * Some infrastructure to simplify handling of software based triggers (i.e. ones with no actual hardware associated with them) * A high resolution timer based trigger. This has been around for years but until the configfs support was ready we didn't have a sensible way of instantiating instances of it (the method used for the sysfs_trigger has never been really satisfactory) New Device Support * AMS iAQ Volatile Organic Compounds sensor support. * Freescale imx7d ADC driver * Maxim MAX30100 oximeter driver (note that for these devices most of the smart stuff will be in userspace - effectively they are just light sensors with some interesting led synchronization as far as the kernel is concerned). * Microchip mcp3421 support added to the mcp3422 driver. * TI adc124s021 support added to the adc128s052 driver. * TI ina219, inda226 power monitors. Note that there is an existing hwmon driver for these parts, the usecase is somewhat different so it is unclear at this point if the hwmon driver will eventually be replaced by a bridge from this driver.

First set of new device support, features and cleanups for IIO in the 4.5 cycle
Usual mixed bag, but the big item perhaps in this series is the DMA buffer support added by Lars-Peter Clausen. It's been in the works for a long time and it will be interesting to see what hardware support shows up now that this is available. New core features + associate cleanup. * Add generic DMA buffer infrastructure * Add a DMAengine framework based buffer Also associated minor changes. - Set the device buffer watermark based on the minimum watermark for all attached buffers rather than just the 'primary' one. - iio_buffer_init - only set the watermark default if one hasn't already been provided. This allows simple support for devices with a fixed watermark. - read only attribute for watermark on fixed watermark devices. - add explicit buffer enable/disable callbacks to allow the buffer to do more than trivial actions when it is being turned on and off. * IIO_VAL_INT support in write_raw_get_fmt function. New device support * Freescale MMA7455/7456L accelerometers * Memsic MXC6255XC accelerometer * ST lis2dh12 accelerometer * TI ADS8688 ADC * TI Palamas (twl6035/7) gpadc New driver features * mma8452 - support either of the available interrupt pins to cope with the case where board layout has lead to a particular one being connected. Staging graduation * Dummy driver - this driver acts as both an example and a test device for those with out hardware to develop userspace code against. Cleanups and minor bits and bobs. * treewide - Sort out the ordering of iio_device_register/unregister vs runtime pm function calls so that it's all nice and consistent and not race prone. - Check sscanf return values. None of the cases will actually happen as the strings are supplied internally, but best to be consistent on this. * ad7780 - switch over to the gpio descriptor interface and remove the now unused platform data which gets rid of a header entirely. * ad7793 - drop a pointless else statement. * at91_adc - Swap kmalloc_array in for a kmalloc doing the same job. * dummy - get rid of some commented out lines that snuck in during the move of the driver. * lm3533-als - Print an error message on provision of an invalid resistance. * mcp320x - Add compatible strings with vendor prefix and deprecate those with no vendor prefix. * mxs-lradc - Use BIT macro in various places rather than shifted ones. * pa12203001 - Power off the chip if the registration fails. * pulsedlight-lidar-lite - add runtime PM support. * xilinx XADC - constify an iio_buffer_setup_ops structure. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJWUcmhAAoJEFSFNJnE9BaIyjYP/0A+CZMUqIGbYG9qFxnq7yYZ 977Wt/gGI8+Jq5RwNw6gTfhp2GrCN+5gzDbE2mBEn94c6SKBrj2Q9trW1FQ+Nhfx 9bZoyq3ZPRCV+efEDGfeK/JWRwv+V6IWwAF2J/iCPWpRMTEsIW5kM1JSO3ISlnma diyil1hefGTJY8aCqGApthfX4fyZK98oCV6zojxpCZfFPdsa+vf5n1RQ143odnOk 6NSfXHYLI+2e+mJ1lw4GdpZdF+rF+7jWsUYC5EDNmvlIJYiKmm13whSQeWO0NHo8 oD0pYboSIWnmdXx4s3RbWF2+Y28O1+oJDKZfXabB8DjVwtvlGnmWBRhgKji2e6E6 Hhct83YbDWtEpbNkXcWpnc5v5ynmAMTYTxADhinTGUtVQh3Q4wWduuoHK6IyeI4s dbfpO2Wh6N/5k3a4UoA69IcI2DzPzb2sIFWpdS8wuNv5xDhV2OmmY2PjTfq2w+Qz hEoMCNDUG6rQAYf4auXK5JjhI4CaG/mz/qjIibTUqGODYECzQQyvq+c2Gdq0S8O/ CUHOgui6aHbyuhWmXlEzhhkjuvBQZYaTxCA+LGMzy8w7UY9m4n5L/fX9M9IfFsMH NFCPrUfmxKPQj/mHlhu7KHaTMUlQ0pTqV5flSwqsjstZ2QddvI5EAKiLwIEhg7/2 RpnOZoiFIxykduEYLxeh =CfCl -----END PGP SIGNATURE----- Merge tag 'iio-for-4.5a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of new device support, features and cleanups for IIO in the 4.5 cycle Usual mixed bag, but the big item perhaps in this series is the DMA buffer support added by Lars-Peter Clausen.

New device support * Freescale MMA7455/7456L accelerometers * Memsic MXC6255XC accelerometer * ST lis2dh12 accelerometer * TI ADS8688 ADC * TI Palamas (twl6035/7) gpadc New driver features * mma8452 - support either of the available interrupt pins to cope with the case where board layout has lead to a particular one being connected. Staging graduation * Dummy driver - this driver acts as both an example and a test device for those with out hardware to develop userspace code against. Cleanups and minor bits and bobs. * treewide - Sort out the ordering of iio_device_register/unregister vs runtime pm function calls so that it's all nice and consistent and not race prone. - Check sscanf return values. None of the cases will actually happen as the strings are supplied internally, but best to be consistent on this. * ad7780 - switch over to the gpio descriptor interface and remove the now unused platform data which gets rid of a header entirely. * ad7793 - drop a pointless else statement. * at91_adc - Swap kmalloc_array in for a kmalloc doing the same job. * dummy - get rid of some commented out lines that snuck in during the move of the driver. * lm3533-als - Print an error message on provision of an invalid resistance. * mcp320x - Add compatible strings with vendor prefix and deprecate those with no vendor prefix. * mxs-lradc - Use BIT macro in various places rather than shifted ones. * pa12203001 - Power off the chip if the registration fails. * pulsedlight-lidar-lite - add runtime PM support. * xilinx XADC - constify an iio_buffer_setup_ops structure. |

iio: Move IIO Dummy Driver out of staging
This patch moves the reference IIO dummy driver from drivers/staging/iio into a separate folder, drivers/iio/dummy and adds the proper Kconfig and Makefile for it. A new config menu entry called IIO dummy driver has also been added in the Industrial I/O support menu, corresponding to this driver.
