2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+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.

2017-06-12ata: Add driver for Faraday Technology FTIDE010Linus Walleij1-0/+21
This adds a driver for the Faraday Technology FTIDE010 PATA IP block. When used with the Storlink/Storm/Cortina Systems Gemini SoC, the PATA interface is accompanied by a PATA<->SATA bridge, so while the device appear as a PATA controller, it attaches physically to SATA disks, and also has a designated memory area with registers to set up the bridge. The Gemini SATA bridge is separated into its own driver file to make things modular and make it possible to reuse the PATA driver as stand-alone on other systems than the Gemini. dmesg excerpt from the D-Link DIR-685 storage router: gemini-sata-bridge 46000000.sata: SATA ID 00000e00, PHY ID: 01000100 gemini-sata-bridge 46000000.sata: set up the Gemini IDE/SATA nexus ftide010 63000000.ata: set up Gemini PATA0 ftide010 63000000.ata: device ID 00000500, irq 26, io base 0x63000000 ftide010 63000000.ata: SATA0 (master) start gemini-sata-bridge 46000000.sata: SATA0 PHY ready scsi host0: pata-ftide010 ata1: PATA max UDMA/133 irq 26 ata1.00: ATA-8: INTEL SSDSA2CW120G3, 4PC10302, max UDMA/133 ata1.00: 234441648 sectors, multi 1: LBA48 NCQ (depth 0/32) ata1.00: configured for UDMA/133 scsi 0:0:0:0: Direct-Access ATA INTEL SSDSA2CW12 0302 PQ: 0 ANSI: 5 ata1.00: Enabling discard_zeroes_data sd 0:0:0:0: [sda] 234441648 512-byte logical blocks: (120 GB/112 GiB) sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA ata1.00: Enabling discard_zeroes_data ata1.00: Enabling discard_zeroes_data sd 0:0:0:0: [sda] Attached SCSI disk After this I can flawlessly mount and read/write copy etc files from /dev/sda[n].

The following is an example of ASL structure in DSDT for a SATA controller, which contains _CLS package to be matched by the ahci_platform driver: Device (AHC0) // AHCI Controller { Name(_HID, "AMDI0600") Name (_CCA, 1) Name (_CLS, Package (3) { 0x01, // Base Class: Mass Storage 0x06, // Sub-Class: serial ATA 0x01, // Interface: AHCI }) Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000) Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 } }) } Also, since ATA driver should not require PCI support for ATA_ACPI, this patch removes dependency in the driver/ata/Kconfig.

Use syscon/regmap to configure the smc. This allows to avoid using at91sam9_smc.h and to compile the driver in a multiplatform configuration. The driver will still not probe until the proper DT bindings are added. That binding will include an atmel,smc property that is a phandle to the SMC the CF controller is connected to.

2015-02-10sata_dwc_460ex: disable COMPILE_TEST againLinus Torvalds1-1/+1
Commit 84683a7e081f ("sata_dwc_460ex: enable COMPILE_TEST for the driver") enabled this driver for non-ppc460-ex platforms, but it was then disabled for ARM and ARM64 by commit 2de5a9c004e9 ("sata_dwc_460ex: disable compilation on ARM and ARM64") because it's too noisy and broken. This disabled is entirely, because it's too noisy on x86-64 too, and there's no point in disabling architectures one by one. At a minimum, the code isn't 64-bit clean, and even on 32-bit it is questionable whether it makes sense.
