  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    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

  • b32de9dd3   ARM: at91: move SoC detection to its own driver ... Browse Code »

    To simplify machine init and as the soc_device struct is not used as the

    The number of register we can safely pass to at91_pm_suspend_in_sram is

    The offsets are automatically generated to avoid hardcoding them.

    Only use SOC_AT91SAM9 for all the at91sam9 SoCs. It removes all the empty
    at91sam9xxx.c SoC files. It also removes the useless at91_init_soc affectation
    procedure and its "init" function pointer.
    Only the SoC detection and display are kept for the at91sam9:
    at91_soc_is_enabled() and at91_boot_soc.map_io() function calls are also
    removed.

    It enables HAVE_AT91_SMD and HAVE_AT91_UTMI for all the sam9 SoCs but this only
    represents 96 bytes of uncompressed kernel code.

    As there is currently no-one to take care of this old !MMU target and as its
    support in recent kernels is a bit rotten, remove this at91x40 support and the
    board file associated with it (at91eb01).
    There are modern ARM !MMU in Mainline now so this target is not interesting for
    building tests anymore. It would be better to start from these modern ARM !MMU
    platforms to reintroduce at91x40 support if needed.

    Most of the new code is for the Keystone Navigator driver, which is

    accelerated network driver and other units.

    Most of the commits are for moving old code around from at91 and omap
    for things that are done in device drivers nowadays.

    drivers directories
