  • 5856d8bd3   ASoC: Replace HTTP links with HTTPS ones ... Browse Code »

    Rationale:
    Reduces attack surface on kernel devs opening the links for MITM
    as HTTPS traffic is much harder to manipulate.

    Deterministic algorithm:
    For each file:
    If not .svg:
    For each line:
    If doesn't contain `\bxmlns\b`:
    For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
    If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
    If both the HTTP and HTTPS versions
    return 200 OK and serve the same content:
    Replace HTTP with HTTPS.

  • 250a15cf5   ASoC: soc-core: remove bus_control ... Browse Code »

    Now, snd_soc_dai_driver::bus_control is used for how to resume.
    But, no driver which has bus_control has DAI driver suspend/resume
    support.
    This patch removes pointless bus_control from ALSA SoC.

  • 7b6e7b137   ASoC: cirrus: ep93xx-i2s: move .suspend/.resume to component ... Browse Code »

    There is no big difference at implementation for .suspend/.resume
    between DAI driver and Component driver.
    But because some driver is using DAI version, thus ALSA SoC needs
    to keep supporting it, hence, framework becoming verbose.
    If we can switch all DAI driver .suspend/.resume to Component driver,
    we can remove verbose code from ALSA SoC.

    Driver is getting its private data via dai->dev.
    But dai->dev and component->dev are same dev, thus, we can convert
    these. For same reason, we can convert dai->active to
    component->active if necessary.

    This patch moves DAI driver .suspend/.resume to Component driver

    ep93xx does not have a proper pinctrl driver, but does things
    ad-hoc through mach/platform.h, which is also used for setting
    up the boards.

    To avoid using mach/*.h headers completely, let's move the interfaces
    into include/linux/soc/. This is far from great, but gets the job
    done here, without the need for a proper pinctrl driver.

  • 98e1241c3   ASoC: cirrus: i2s: IRQ-based stream watchdog ... Browse Code »

    I2S controller on EP93xx seems to have undocumented HW issue. According to
    "EP93xx User’s Guide", controller can handle underflow and either transmit
    last sample or zeroes in such case until FIFO is filled again. In reality
    undeflow conditions seem to confuse internal state machine from time to
    time and the whole stream gets shifted by one byte (as captured by logic
    analyser on the I2S outputs). One could only hear noise instead of original
    stream and this continues until the FIFO is disabled and enabled again.

    Work this around by watching underflow interrupt and resetting I2S TX
    channel + fill FIFO with zero samples until DMA catches up again. This is
    a nasty workaround, but it works. Hence, Kconfig option to disable it in
    case of problems.

  • 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

  • acde50a7b   ASoC: dmaengine_pcm: Make FLAG_NO_RESIDUE internal ... Browse Code »

    Whether residue can be reported or not is not a property of the audio
    controller but of the DMA controller. The FLAG_NO_RESIDUE was initially
    added when the DMAengine framework had no support for describing the residue
    reporting capabilities of the controller. Support for this was added quite a
    while ago and recently the DMAengine framework started to complain if a
    driver does not describe its capabilities and a lot of patches have been
    merged that add support for this where it was missing. So it should be safe
    to assume that driver on actively used platforms properly implement the DMA
    capabilities API.

    This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio
    controller drivers to manually set the flag. If a DMA driver against
    expectations does not support reporting its capabilities for now the generic
    DMAengine PCM driver will now emit a warning and simply assume that residue
    reporting is not supported. In the future this might be changed to aborting
    with an error.

  • bc2632140   ASoC: Rename snd_soc_dai_driver struct ac97_control field to bus_control ... Browse Code »

    Setting the ac97_control field on a CPU DAI tells the ASoC core that this
    DAI in addition to audio data also transports control data to the CODEC.
    This causes the core to suspend the DAI after the CODEC and resume it before
    the CODEC so communication to the CODEC is still possible. This is not
    necessarily something that is specific to AC'97 and can be used by other
    buses with the same requirement. This patch renames the flag from
    ac97_control to bus_control to make this explicit.

    While we are at it also change the type from int to bool.

    The following semantich patch was used for automatic conversion of the
    drivers:
    //

    identifier drv;
    @@
    struct snd_soc_dai_driver drv = {
