mips: select legacy gpiolib interfaces where usedA few old machines have not been converted away from the old-stylegpiolib interfaces. Make these select the new CONFIG_GPIOLIB_LEGACYsymbol so the code still works where it is needed but can be leftout otherwise.This is the list of all gpio_request() calls in mips: arch/mips/alchemy/devboards/db1000.c: gpio_request(19, "sd0_cd"); arch/mips/alchemy/devboards/db1000.c: gpio_request(20, "sd1_cd"); arch/mips/alchemy/devboards/db1200.c: gpio_request(215, "otg-vbus"); arch/mips/bcm47xx/workarounds.c: err = gpio_request_one(usb_power, GPIOF_OUT_INIT_HIGH, "usb_power"); arch/mips/bcm63xx/boards/board_bcm963xx.c: gpio_request_one(board.ephy_reset_gpio, arch/mips/txx9/rbtx4927/setup.c: gpio_request(15, "sio-dtr");Most of these should be easy enough to change to modern gpio descriptorsor remove if they are no longer in use.Signed-off-by: Arnd Bergmann Reviewed-by: Bartosz Golaszewski Reviewed-by: Linus Walleij Signed-off-by: Thomas Bogendoerfer List of files: /linux/arch/mips/alchemy/Kconfig

b24413180f5600bcb3bb70fbed5cf186b60864bd - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 15:07:57 +0100

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense 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 bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe 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 caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase 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 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately 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 licenseidentifiers 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 thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion 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 correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux/arch/mips/alchemy/Kconfig

MIPS: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBThis replaces:- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly.- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it.When ordering the symbols the following rationale was used:if the selects were in alphabetical order, I moved select GPIOLIBto be in alphabetical order, but if the selects were notmaintained in alphabetical order, I just replaced"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".Cc: Michael Büsch Cc: linux-mips@linux-mips.orgAcked-by: Ralf Baechle Signed-off-by: Linus Walleij List of files: /linux/arch/mips/alchemy/Kconfig

Sun, 02 Aug 2015 18:30:11 +0200

MIPS: Remove all the uses of custom gpio.hCurrently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPSmachines, and each machine type provides its own gpio.h. Howeveronly a handful really implement the GPIO API, most just forwardeverythings to gpiolib.The Alchemy machine is notable as it provides a system to allowimplementing the GPIO API at the board level. But it is not used byany board currently supported, so it can also be removed.For most machine types we can just remove the custom gpio.h, as wellas the custom wrappers if some exists. Some of the code found inthe wrappers must be moved to the respective GPIO driver.A few more fixes are need in some drivers as they rely on linux/gpio.hto provides some machine specific definitions, or used asm/gpio.hinstead of linux/gpio.h for the gpio API.Signed-off-by: Alban Bedel Reviewed-by: Linus Walleij Cc: linux-mips@linux-mips.orgCc: Hauke Mehrtens Cc: Rafał Miłecki Cc: Bartlomiej Zolnierkiewicz Cc: Tejun Heo Cc: Alexandre Courbot Cc: Dmitry Torokhov Cc: Florian Fainelli Cc: Manuel Lauss Cc: Joe Perches Cc: Daniel Walter Cc: Sergey Ryazanov Cc: Huacai Chen Cc: James Hartley Cc: Andrew Bresticker Cc: Paul Burton Cc: Jiri Kosina Cc: Bjorn Helgaas Cc: Wolfram Sang Cc: Randy Dunlap Cc: Varka Bhadram Cc: Masanari Iida Cc: Tomi Valkeinen Cc: Michael Buesch Cc: abdoulaye berthe Cc: linux-kernel@vger.kernel.orgCc: linux-ide@vger.kernel.orgCc: linux-gpio@vger.kernel.orgCc: linux-input@vger.kernel.orgCc: netdev@vger.kernel.orgPatchwork: https://patchwork.linux-mips.org/patch/10828/Signed-off-by: Ralf Baechle List of files: /linux/arch/mips/alchemy/Kconfig
