  • 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 .

  • 205d231bf   ASoC: Remove -dai suffix from i.MX SSI driver ... Browse Code »

    While it is a generic serial port in practice the i.MX SSI is only supported
    in Linux as an audio port (the i.MX has dedicated SPI controllers and so on).
    This means we don't need to disambiguate against other uses of the hardware
    and so can drop the -dai suffix from the driver name which fixes merge
    issues with the i.MX tree in -next.

  • 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().

  • eeec12468   ASoC: Wolfson Microelectronics 1133-EV1 audio support ... Browse Code »

    Initial support for audio using the 1133-EV1 audio and PMIC module for
    the i.MX31ADS. Currently only playback is supported, and the FIQ DMA
    driver has performance problems at higher sample rates which cause
    audible dropouts.

    This driver is based heavily on an out of tree one written by Liam
    Girdwood.
