  • 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 =
    { ... };

  • 839d271c5   ASoC: codecs: Remove unused reg_cache fields from device structs ... Browse Code »

    The multi-component patch(commit f0fba2ad1) moved the allocation of the
    register cache from the driver to the ASoC core. Most drivers where adjusted to
    this, but there are quite a few drivers left which now have an unused reg_cache field in
    their private device struct.
    This patch removes these unused fields.

  • 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.

    "ASoC: Refactor WM8731 device registration" to make UDA1380 use standard
    device instantiation. Similarly, the I2C device registration temporarily
    moves into the magician machine driver before it will find its final
    resting place in the board file.

    At the same time, platform specific configuration is moved to platform data
    and common power/reset GPIO handling moves into the codec driver.

    Considering the fact that most cpu_dai or codec_dai are using a same
    'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better
    made a pointer instead, to make sharing easier and code a bit cleaner.

    The patch below is rather preliminary since the asoc tree is being
    actively developed, and this touches almost every piece of code,
    (and possibly many others in development need to be changed as
    well). Building of all codecs are OK, yet to every SoC, I didn't test
    that.

    Currently this is done at module probe time since ASoC ties in codec
    device probe to the instantiation of the entire ASoC device. Subsequent
    patches will refactor the codec drivers to handle probing separately.
    Note that the core does not yet use this information.

    AC97 is special since the codec is controlled over the AC97 link but
    we want to give the machine driver a chance to set up the system before
    trying to instantiate since it may need to do configuration before the
    AC97 link will operate

    Backport this change.

    This paves the way for future work allowing any combination of DAIs to

  • 3051e41ab   ALSA: ASoC: Fix double free and memory leak in many codec drivers ... Browse Code »

    Many SoC audio codec drivers have improper freeing of memory in error
    paths.

    * codec is allocated in the platform device probe function, but is not
    freed there in case of error. Instead it is freed in the i2c device
    probe function's error path. However the success or failure of both
    functions is not linked, so this could result in a double free (if
    the platform device is successfully probed, the i2c device probing
    fails and then the platform driver is unregistered.)

    * codec->private_data is allocated in many platform device probe
    functions but not freed in their error paths.

    This patch hopefully solves all these problems.
