* 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.

* ARM: davinci: make I2C support optionalArnd Bergmann2016-02-171-13/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The davinci platform has tried to get support for the EEPROM right, but failed to get a clean build so far. At the moment, we get a warning whenever CONFIG_SYSFS is disabled, as that is needed by EEPROM_AT24: warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS) Kevin Hilman initially added the 'select' to ensure that EEPROM_AT24 is always enabled in machines that really want it for normal operation (i.e. for reading the MAC address). This broke when I2C was disabled, and Russell King followed up with another patch to select that as well. I now see that the SYSFS dependency is still missing, which leaves us with three options: a) add 'select SYSFS' in addition to the others b) change AT24_EEPPROM to work without sysfs (should be possible) c) remove all those selects again and get the files to build when I2C is disabled. I would really hate to do a) because adding select statements that hardwire user-selectable symbols is generally a bad idea. I first tried b) but then ended up redoing the patch from scratch to approach c), so we can also remove the other selects. I checked that CONFIG_I2C is still enabled with davinci_all_defconfig, so that does not have to change.

| | | | | | | | | | | | | We already forbid that combination when AUTO_ZRELADDR is disabled, for the same reason that the two have their RAM at different physical addresses as seen from the CPU. This does the same change for PATCH_PHYS_VIRT: if you disable either of the options, Kconfig now enforces that you have to pick one or the other SoC family.

* | ARM: davinci: fix Kconfig for DA850_EVMArnd Bergmann2014-03-211-5/+0
|/ | | | | | | | | | | | | | | | | | | | | The DAVINCI_DA850_EVM board uses an unusual method to enable the GPIO_PCA953X and KEYBOARD_GPIO_POLLED symbols, which leads to the dependencies on these symbols being ignored. As GPIO_PCA953X actually requires I2C, that can lead to build failures when I2C is disabled. This patch removes the duplicate symbol definitions and instead enables them from the davinci_all_defconfig file. A different question whether we actually want to automatically enable them at all or rather put them into defconfig, but that should be a separate patch.

* davinci: introduce support for AM1x ARM9 microprocessorsSekhar Nori2010-09-241-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | The Sitara AM17x SoCs from TI are an OMAP-L137 pin-to-pin compatible ARM9 microprocessor offering from TI. The Sitara AM18x SoCs from TI are an OMAP-L138 pin-to-pin compatible ARM9 microprocessor offering from TI. More information about these processors available at: www.ti.com/am1x Because of their compatibiliy with OMAP-L1x, the kernel support for OMAP-L1x is fully relevant to AM1x processors. This patch updates the Kconfig prompt and help text to include the AM1x part names to help users select configurations required for these parts easily. Also, the hardware information that shows up in /proc/cpuinfo is updated to show applicability of the respective OMAP-L1x EVMs for AM1x parts.

* Davinci: tnetv107x soc supportCyril Chemparathy2010-06-211-0/+5
| | | | | | | | | | | | | | | | | | TNETV107X is a Texas Instruments SOC that shares a number of common features with the Davinci architecture. Some of the key differences between traditional Davincis and this new SOC are as follow: 1. The SOCs clock architecture includes a new spread-spectrum PLL. Some elements of the clock architecture are reused from Davinci (e.g. LPSC), but the PLL related code is overridden using existing interfaces in "struct clk". 2. The MMR layout on this SOC is substantially different from Davinci. Consequently, the fixed I/O map is a whole lot more convoluted (more so than DA8xx). The net impact here is that IO_ADDRESS() will not work on this SoC, and therefore all mappings have to be through ioremap().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DM6467T (T for Turbo) is a newer and faster DM6467 part from TI. The new part supports 1080p video and has the ARM running at 495MHz. More SoC information: http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html Spectrum Digital, Inc has a new EVM for this part. It is _mostly_ same as the older DM6467 EVM except for a 33MHz crystal input and THS8200 video encoder for 1080p support. The meat of this patch is dedicated to initializing the crystal frequency from EVM board file. Additional notes: I did consider some alternative ways to make the crystal input board specific including - (1) having board code initialize the crystal frequency using the first member of soc_info->cpu_clks array (2) introducing a new ref_clk_rate member in soc_info structure. But, the current way seems to be the simplest and least intruding considering that both the clock array and SoC info structure are actually private to the SoC file. Also the fact that davinci_common_init() initializes both the soc_info and clocks in one go. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

| | | | | | | | | | | | | | | | DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY is enabled by proper programming of the IO Expander (TCA6416) ports. Also for RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds support for RMII PHY. This patch also adds a menuconfig option to select one or no peripheral connected to expander. Currently, sub-options in this menu are RMII and no peripheral.This menuconfig option is similar to the one present for UI card on DA830/OMAP-L137 EVM.

* davinci: da8xx: Add base DA830/OMAP-L137 SoC supportMark A. Greer2009-08-261-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The da830/omap l137 is a new SoC from TI that is similar to the davinci line. Since its so similar to davinci, put the support for the da830 in the same directory as the davinci code. There are differences, however. Some of those differences prevent support for davinci and da830 platforms to work in the same kernel binary. Those differences are: 1) Different physical address for RAM. This is relevant to Makefile.boot addresses and PHYS_OFFSET. The Makefile.boot issue isn't truly a kernel issue but it means u-boot won't work with a uImage including both architectures. The PHYS_OFFSET issue is addressed by the "Allow for runtime-determined PHYS_OFFSET" patch by Lennert Buytenhek but it hasn't been accepted yet. 2) Different uart addresses. This is only an issue for the 'addruart' assembly macro when CONFIG_DEBUG_LL is enabled. Since the code in that macro is called so early (e.g., by _error_p in kernel/head.S when the processor lookup fails), we can't determine what platform the kernel is running on at runtime to use the correct uart address. These areas have compile errors intentionally inserted to indicate to the builder they're doing something wrong. A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added to distinguish between a true davinci architecture and the da830 architecture. Note that the da830 currently has an issue with writeback data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be enabled when building a da830 kernel.
