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.

ARM: OMAP5+: Fix inverted nirq pin interrupts with irq_set_type Commit 83a86fbb5b56 ("irqchip/gic: Loudly complain about the use of IRQ_TYPE_NONE") started warning about incorrect dts usage for irqs. ARM GIC only supports active-high interrupts for SPI (Shared Peripheral Interrupts), and the Palmas PMIC by default is active-low. Palmas PMIC allows changing the interrupt polarity using register PALMAS_POLARITY_CTRL_INT_POLARITY, but configuring sys_nirq1 with a pull-down and setting PALMAS_POLARITY_CTRL_INT_POLARITY made the Palmas RTC interrupts stop working. This can be easily tested with kernel tools rtctest.c. Turns out the SoC inverts the sys_nirq pins for GIC as they do not go through a peripheral device but go directly to the MPUSS wakeupgen. I've verified this by muxing the interrupt line temporarily to gpio_wk16 instead of sys_nirq1. with a gpio, the interrupt works fine both active-low and active-high with the SoC internal pull configured and palmas polarity configured. But as sys_nirq1, the interrupt only works when configured ACTIVE_LOW for palmas, and ACTIVE_HIGH for GIC. Note that there was a similar issue earlier with tegra114 and palmas interrupt polarity that got fixed by commit df545d1cd01a ("mfd: palmas: Provide irq flags through DT/platform data"). However, the difference between omap5 and tegra114 is that tegra inverts the palmas interrupt twice, once when entering tegra PMC, and again when exiting tegra PMC to GIC. Let's fix the issue by adding a custom wakeupgen_irq_set_type() for wakeupgen and invert any interrupts with wrong polarity. Let's also warn about any non-sysnirq pins using wrong polarity. Note that we also need to update the dts for the level as IRQ_TYPE_NONE never has irq_set_type() called, and let's add some comments and use proper pin nameing to avoid more confusion later on.

ARM GIC only supports active-high interrupts for SPI (Shared Peripheral Interrupts), and the Palmas PMIC by default is active-low. Palmas PMIC allows changing the interrupt polarity using register PALMAS_POLARITY_CTRL_INT_POLARITY, but configuring sys_nirq1 with a pull-down and setting PALMAS_POLARITY_CTRL_INT_POLARITY made the Palmas RTC interrupts stop working. This can be easily tested with kernel tools rtctest.c. Turns out the SoC inverts the sys_nirq pins for GIC as they do not go through a peripheral device but go directly to the MPUSS wakeupgen. I've verified this by muxing the interrupt line temporarily to gpio_wk16 instead of sys_nirq1. with a gpio, the interrupt works fine both active-low and active-high with the SoC internal pull configured and palmas polarity configured. But as sys_nirq1, the interrupt only works when configured ACTIVE_LOW for palmas, and ACTIVE_HIGH for GIC. Note that there was a similar issue earlier with tegra114 and palmas interrupt polarity that got fixed by commit df545d1cd01a ("mfd: palmas: Provide irq flags through DT/platform data"). However, the difference between omap5 and tegra114 is that tegra inverts the palmas interrupt twice, once when entering tegra PMC, and again when exiting tegra PMC to GIC. Let's fix the issue by adding a custom wakeupgen_irq_set_type() for wakeupgen and invert any interrupts with wrong polarity. Let's also warn about any non-sysnirq pins using wrong polarity. Note that we also need to update the dts for the level as IRQ_TYPE_NONE never has irq_set_type() called, and let's add some comments and use proper pin nameing to avoid more confusion later on.
