  • 75d9ac46b   ASoC: Allow DAI formats to be specified in the dai_link ... Browse Code »
    43

    For almost all machines the DAI format is a constant, always set to the
    same thing. This means that not only should we normally set it on init
    rather than in hw_params() (where it has been for historical reasons) we
    should also allow users to configure this by setting a variable in the
    dai_link structure. The combination of these two will make many machine
    drivers even more data driven.

    Implement a new dai_fmt field in the dai_link doing just that. Since 0 is
    a valid value for many format flags and we need to be able to tell if the
    field is actually set also add one to all the values used to configure
    formats.

  • 17841020e   ASoC: soc-core: symmetry checking for each DAIs separately ... Browse Code »

    The orginal code does not cover the case that one DAI such as codec
    may be shared between other two DAIs(CPU).
    When do symmetry checking, altough the codec DAI requires symmetry,
    the two CPU DAIs may still be configured to run on different rates.

    We change to check each DAI's state separately instead of only checking
    the dai link to prevent this issue.

    Some ASoC components depend on other ASoC components to provide clocks and
    power resources in order to probe() and vice versa for remove().

    Allow components to be ordered so that components can be probed() and removed()
    in sequences that conform to their dependencies.

  • 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().

    All other platforms are fixed blindly, I couldn't even compile-test

    The delay callback can be used by the core to query the delay
    on the dai caused by FIFO or delay in the platform side.
    In case if both CPU and CODEC dai has FIFO the delay reported
    by each will be added to form the full delay on the chain.
    If none of the dai has FIFO, than the delay will be kept as
    zero.

    The patch adds an interface to set the relationship between audio

    because audio channel n doesn't always use slot n in all platforms. And
    for some devices, the relationship even can change with sound mode
    switch in 2.1,3.1,4.1,5.1,6.1,7.1 etc.

  • 4072604b9   ASoC: Remove unused DAI format defines ... Browse Code »

    The defines for TDM and synchronous clocks are not used - they are
    mostly a legacy of the automatic clocking configuration. TDM will
    require configuration of the number of timeslots and which ones to use
    so can't be fit into the DAI format and synchronous mode is handled by
    symmetric_rates (and needs to be done by constraints rather than when
    the DAI format is being configured).

  • 06f409d76   ASoC: Provide core support for symmetric sample rates ... Browse Code »

    Many devices require symmetric configurations of capture and playback
    data formats, often due to shared clocking but sometimes also due to
    other shared playback and record configuration in the device. Start
    providing core support for this by allowing the DAIs or the machine
    to specify that the sample rates used should be kept symmetric.

    A flag symmetric_rates is provided in the snd_soc_dai and
    snd_soc_dai_link structures. If this is set in either of the DAIs or in
    the machine then a constraint will be applied when a stream is already
    open preventing any changes in sample rate.

  • 6335d0554   ASoC: make ops a pointer in 'struct snd_soc_dai' ... Browse Code »

    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.

    DAI type information is only ever used within ASoC in order to special

    support multi function DAIs which can be configured for several modes
    it is more trouble than it's worth to maintain anything other than a
    flag identifying AC97 DAIs so remove the type field and replace it with
    an ac97_control flag.
