  • 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 =
    { ... };
    //

  • 2c66cb99d   ASoC: Blackfin: push down SPORT settings from global variables ... Browse Code »

    Now that we have multi-component support, take the time to unify the
    SPORT implementations a bit and make the setup dynamic. This kills
    off the global sport_handle which was shared across all the Blackfin
    machine drivers. The pin management aspect is off loaded to platform
    resources, and now multiple SPORTs can be instantiated simultaneously.

  • 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().

  • 01e2ab207   ASoC: blackfin I2S(TDM mode) CPU DAI driver ... Browse Code »

    The I2S DAI driver for blackfin SPORT, but works in TDM mode.
    I2S is not a special case of TDM with only left and right two slots for
    SPORT interface. I2S coordinates with TDM in SPORT, but not a part of
    TDM. TDM require different hardware configuration with I2S, not only
    different slot number. One is "Stereo Serial Operation" mode of SPORT,
    the other one is "Multichannel Operation" mode. They are incompatible
    at the same time.
    Hardware and DMA description and data transfer flow are much different
    for I2S and TDM. Merging them as a whole will be very ugly and difficult
    to maintain.
    So we don't define a new DAI type, but give two DAI instances for standard
    I2S and TDM, both in I2S-family DAI type. The TDM instance still uses the
    I2S-family DAI type.
