    Now snd_ac97_bus() takes the const ops pointer, so we can define the
    snd_ac97_bus_ops locally as const as well for further optimization.

    There should be no functional changes by this patch.

  • 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

  • e30129aed   ALSA: arm: Fix empty menuconfig SND_ARM ... Browse Code »

    commit 3c8f7710c1c4 ("ASoC: fix broken pxa SoC support") has removed
    the SND_ARM dependency from SND_PXA2XX_LIB and SND_PXA2XX_LIB_AC97,
    by moving these config entries outside of the "if SND_ARM ... endif"
    construct.

    However, by placing these 2 symbols right between the SND_ARM
    menuconfig definition and the first SND_ARM menu entry, the side
    effect is that the SND_ARM menu becomes empty and all the config
    entries caught between "if SND_ARM ... endif" no more belong to
    menuconfig SND_ARM, but to its parent (menuconfig SND).

    Fix this.

  • f6e45661f   dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc() ... Browse Code »

    Rename dma_*_writecombine() to dma_*_wc(), so that the naming
    is coherent across the various write-combining APIs. Keep the
    old names for compatibility for a while, these can be removed
    at a later time. A guard is left to enable backporting of the
    rename, and later remove of the old mapping defines seemlessly.

    Build tested successfully with allmodconfig.

    The following Coccinelle SmPL patch was used for this simple
    transformation:

    @ rename_dma_alloc_writecombine @
    expression dev, size, dma_addr, gfp;
    @@

    -dma_alloc_writecombine(dev, size, dma_addr, gfp)
    +dma_alloc_wc(dev, size, dma_addr, gfp)

    @ rename_dma_free_writecombine @
    expression dev, size, cpu_addr, dma_addr;
    @@

    -dma_free_writecombine(dev, size, cpu_addr, dma_addr)
    +dma_free_wc(dev, size, cpu_addr, dma_addr)

    @ rename_dma_mmap_writecombine @
    expression dev, vma, cpu_addr, dma_addr, size;
    @@

    -dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
    +dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)

    We also keep the old names as compatibility helpers, and
    guard against their definition to make backporting easier.

    This patch removes the old PXA DMA API usage and switches over to
    generic functions provided by snd-soc-dmaengine-pcm.

    More cleanups may be done on top of this, and some function stubs can
    now be removed completetly. However, the intention here was to keep
    the transition as small as possible.

    This was tested on the mioa701 pxa27x board.

  • 3c8f7710c   ASoC: fix broken pxa SoC support ... Browse Code »

    The previous fix of pxa library support, which was introduced to fix the
    library dependency, broke the previous SoC behavior, where a machine
    code binding pxa2xx-ac97 with a coded relied on :
    - sound/soc/pxa/pxa2xx-ac97.c
    - sound/soc/codecs/XXX.c

    For example, the mioa701_wm9713.c machine code is currently broken. The
    "select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
    compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
    in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

    Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
    pxa2xx-ac97 compilation.

  • b45281412   ASoC: pxa: remove mach header dependency ... Browse Code »

    As we are moving the mmp platform towards multiplatform support,
    we have to stop including platform header files.

    This changes the pxa-ssp sound driver file to no longer depend
    on mach/hardware.h and mach/dma.h. The code using the definitions
    from those headers is actually gone already, the only thing
    that was still being used was the pxa_dma_desc typedef, which
    we can easily work around by using the normal 'struct pxa_dma_desc'
    name.

    The pxa2xx-dma driver still uses this header, so we include it
    explicitly there, which is ok because that is only used on pxa,
    not on mmp.

  • 8ceafbfa9   Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm ... Browse Code »

    Pull DMA mask updates from Russell King:
    "This series cleans up the handling of DMA masks in a lot of drivers,
    fixing some bugs as we go.

    Some of the more serious errors include:
    - drivers which only set their coherent DMA mask if the attempt to
    set the streaming mask fails.
    - drivers which test for a NULL dma mask pointer, and then set the
    dma mask pointer to a location in their module .data section -
    which will cause problems if the module is reloaded.

    To counter these, I have introduced two helper functions:
    - dma_set_mask_and_coherent() takes care of setting both the
    streaming and coherent masks at the same time, with the correct
    error handling as specified by the API.
    - dma_coerce_mask_and_coherent() which resolves the problem of
    drivers forcefully setting DMA masks. This is more a marker for
    future work to further clean these locations up - the code which
    creates the devices really should be initialising these, but to fix
    that in one go along with this change could potentially be very
    disruptive.

    The last thing this series does is prise away some of Linux's addition
    to "DMA addresses are physical addresses and RAM always starts at
    zero". We have ARM LPAE systems where all system memory is above 4GB
    physical, hence having DMA masks interpreted by (eg) the block layers
    as describing physical addresses in the range 0..DMAMASK fails on
    these platforms. Santosh Shilimkar addresses this in this series; the
    patches were copied to the appropriate people multiple times but were
    ignored.

    Fixing this also gets rid of some ARM weirdness in the setup of the
    max*pfn variables, and brings ARM into line with every other Linux
    architecture as far as those go"

  • c9bd5e690   DMA-API: sound: fix dma mask handling in a lot of drivers ... Browse Code »

    This code sequence is unsafe in modules:

    static u64 mask = DMA_BIT_MASK(something);
    ...
    if (!dev->dma_mask)
    dev->dma_mask = &mask;

    as if a module is reloaded, the mask will be pointing at the original
    module's mask address, and this can lead to oopses. Moreover, they
    all follow this with:

    if (!dev->coherent_dma_mask)
    dev->coherent_dma_mask = mask;

    where 'mask' is the same value as the statically defined mask, and this
    bypasses the architecture's check on whether the DMA mask is possible.

    Fix these issues by using the new dma_coerce_coherent_and_mask()
    function.
