  • 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

  • 0865805d8   clk: at91: add audio pll clock drivers ... Browse Code »

    This new clock driver set allows to have a fractional divided clock that
    would generate a precise clock particularly suitable for audio
    applications.

    The main audio pll clock has two children clocks: one that is connected
    to the PMC, the other that can directly drive a pad. As these two routes
    have different enable bits and different dividers and divider formulas,
    they are handled by two different drivers. Each of them could modify the
    rate of the main audio pll parent.

    The main audio pll clock can output 620MHz to 700MHz.

  • dbeb0c8e8   ARM: at91: don't select CONFIG_ARM_CPU_SUSPEND for old platforms ... Browse Code »

    My previous patch fixed a link error for all at91 platforms when
    CONFIG_ARM_CPU_SUSPEND was not set, however this caused another
    problem on a configuration that enabled CONFIG_ARCH_AT91 but none
    of the individual SoCs, and that also enabled CPU_ARM720 as
    the only CPU:

    warning: (ARCH_AT91 && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && SOC_IMX6 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM && EXYNOS_CPU_SUSPEND && ARCH_VEXPRESS_TC2_PM && ARM_BIG_LITTLE_CPUIDLE && ARM_HIGHBANK_CPUIDLE && QCOM_PM) selects ARM_CPU_SUSPEND which has unmet direct dependencies (ARCH_SUSPEND_POSSIBLE)

    arch/arm/kernel/suspend.o: In function `__cpu_suspend_save':
    suspend.c:(.text+0x134): undefined reference to `cpu_arm720_do_suspend'

    This improves the hack some more by only selecting ARM_CPU_SUSPEND
    for the part that requires it, and changing pm.c to drop the
    contents of unused init functions so we no longer refer to
    cpu_resume on at91 platforms that don't need it.

    When CONFIG_ARCH_AT91 is enabled, but none of the specific SoC support
    is in use, some at91 specific drivers fail to link:

    drivers/tty/serial/atmel_serial.o: In function `atmel_serial_suspend':

    This changes the at91_suspend_entering_slow_clock hack once more, adding
    an alternative inline implementation that is used exactly in those cases
    that don't provide the normal implementation.

  • 60b89f192   ARM: at91: pm: cpu_idle: switch DDR to power-down mode ... Browse Code »

    On some DDR controllers, compatible with the sama5d3 one,
    the sequence to enter/exit/re-enter the self-refresh mode adds
    more constrains than what is currently written in the at91_idle
    driver. An actual access to the DDR chip is needed between exit
    and re-enter of this mode which is somehow difficult to implement.
    This sequence can completely hang the SoC. It is particularly
    experienced on parts which embed a L2 cache if the code run
    between IDLE calls fits in it...

    Moreover, as the intention is to enter and exit pretty rapidly
    from IDLE, the power-down mode is a good candidate.

    So now we use power-down instead of self-refresh. As we can
    simplify the code for sama5d3 compatible DDR controllers,
    we instantiate a new sama5d3_ddr_standby() function.

    - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB

    When ordering the symbols the following rationale was used:
    if the selects were in alphabetical order, I moved select GPIOLIB
    to be in alphabetical order, but if the selects were not
    maintained in alphabetical order, I just replaced
    "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".
