  • 3cb81651d   ASoC: da7210: Minor improvements and a bugfix ... Browse Code »

    This patch improves playback quality for few sample rates like 8000 and
    11025 Hz.

    This also fixes an issue observed during testing of pll slave mode. Due
    to the issue, on some rare occasions there was no sound output for first
    time playback after system boot, though all subsequent playbacks were
    fine. It was mainly because of the sequence in which SRM bit was
    enabled.

    This patch fixes a bug discovered during testing of non pll slave mode.
    Due to the bug chip was not getting correctly configured and as a result
    there was no sound output while playback. After applying this patch,
    both pll and non pll modes work fine.

  • 570aa7bae   ASoC: da7210: Add support for PLL and SRM ... Browse Code »

    Current DA7210 driver does support PLL mode fully. It uses fixed
    value of input master clock and PLL mode is enabled and disabled based
    on the sampling frequency being used for playback or recording. It also
    doesn't support Sample Rate Measurement feature of DA7210 hardware.

    This patch adds full support for PLL and SRM. Basically following three
    modes of operation are possible for DA7210 hardware,

    (1) I2S SLAVE mode with PLL bypassed
    (2) I2S SLAVE mode with PLL enabled
    (3) I2S Master mode with PLL enabled

    This patch adds support for all three modes. Also, in case of SLAVE mode
    with PLL, it supports SRM (Sample Rate Measurement) feature of the chip.

    Actually this patch was submitted earlier and received some review
    comments, but after that the driver got update by other patches. Because
    of that, I am considering this as new patch and not versioning it based
    of previous patches. This version tries to take care of all review
    comments received for earlier submissions.

  • e6968a171   ASoC: codecs: Remove rtd->codec usage from CODEC drivers ... Browse Code »

    In order to support CODECCODEC links remove the assumption that there
    is only a single CODEC on a DAI link by removing the use of the CODEC
    pointer in the rtd from the CODEC drivers. They are already being passed
    their DAI whenever they are passed an rtd and can get the CODEC from
    there.

  • 85e7652d8   ASoC: Constify snd_soc_dai_ops structs ... Browse Code »

    Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
    introduced the possibility to have constant DAI ops structures, yet this is
    barley used in both existing drivers and also new drivers being submitted,
    although none of them modifies its DAI ops structure. The later is not
    surprising since existing drivers are often used as templates for new drivers.
    So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
    the issue altogether.

    The patch was generated with the following coccinelle semantic patch:
    //
    @@
    identifier ops;
    @@
    -struct snd_soc_dai_ops ops =
    +const struct snd_soc_dai_ops ops =
    { ... };

  • ce6120cca   ASoC: Decouple DAPM from CODECs ... Browse Code »

    Decoupling Dynamic Audio Power Management (DAPM) from codec devices is
    required when developing ASoC further. Such as for other ASoC components to
    have DAPM widgets or when extending DAPM to handle cross-device paths.

    This patch decouples DAPM related variables from struct snd_soc_codec and
    moves them to new struct snd_soc_dapm_context that is used to encapsulate
    DAPM context of a device. ASoC core and API of DAPM functions are modified
    to use DAPM context instead of codec.

    This patch does not change current functionality and a large part of changes
    come because of structure and internal API changes.

    Core implementation is from Liam Girdwood with some
    minor core changes, codecs and machine driver conversions from
    Jarkko Nikula .

  • f0fba2ad1   ASoC: multi-component - ASoC Multi-Component Support ... Browse Code »

    This patch extends the ASoC API to allow sound cards to have more than one
    CODEC and more than one platform DMA controller. This is achieved by dividing
    some current ASoC structures that contain both driver data and device data into
    structures that only either contain device data or driver data. i.e.

    struct snd_soc_codec ---> struct snd_soc_codec (device data)
    +-> struct snd_soc_codec_driver (driver data)

    struct snd_soc_platform ---> struct snd_soc_platform (device data)
    +-> struct snd_soc_platform_driver (driver data)

    struct snd_soc_dai ---> struct snd_soc_dai (device data)
    +-> struct snd_soc_dai_driver (driver data)

    struct snd_soc_device ---> deleted

    This now allows ASoC to be more tightly aligned with the Linux driver model and
    also means that every ASoC codec, platform and (platform) DAI is a kernel
    device. ASoC component private data is now stored as device private data.

    The ASoC sound card struct snd_soc_card has also been updated to store lists
    of it's components rather than a pointer to a codec and platform. The PCM
    runtime struct soc_pcm_runtime now has pointers to all its components.

    This patch adds DAPM support for ASoC multi-component and removes struct
    snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
    or runtime PCM level basis rather than using snd_soc_socdev.

    Other notable multi-component changes:-

    * Stream operations now de-reference less structures.
    * close_delayed work() now runs on a DAI basis rather than looping all DAIs
    in a card.
    * PM suspend()/resume() operations can now handle N CODECs and Platforms
    per sound card.
    * Added soc_bind_dai_link() to bind the component devices to the sound card.
    * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
    DAI link components.
    * sysfs entries can now be registered per component per card.
    * snd_soc_new_pcms() functionailty rolled into dai_link_probe().
    * snd_soc_register_codec() now does all the codec list and mutex init.

    This patch changes the probe() and remove() of the CODEC drivers as follows:-

    o Make CODEC driver a platform driver
    o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
    o Removed all static codec pointers (drivers now support > 1 codec dev)
    o snd_soc_register_pcms() now done by core.
    o snd_soc_register_dai() folded into snd_soc_register_codec().

  • b2c812e22   ASoC: Add indirection for CODEC private data ... Browse Code »

    One of the features of the multi CODEC work is that it embeds a struct
    device in the CODEC to provide diagnostics via a sysfs class rather than
    via the device tree, at which point it's much better to use the struct
    device private data rather than having two places to store it. Provide
    an accessor function to allow this change to be made more easily, and
    update all the CODEC drivers are updated.

    To ensure use of the accessor the private data structure member is
    renamed, meaning that if code developed with older an older core that
    still uses private_data is merged it will fail to build.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
