  • 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().

  • 6a84c234d   ASoC: Fix typo in MPC5200 PSC AC97 driver Kconfig ... Browse Code »

    ALSA SoC drivers should be specify SND_SOC_AC97_BUS instead, not AC97_BUS.
    Without SND_SOC_AC97_BUS defined, an AC97 device will not get correctly
    registered on the AC97 bus, which prevents thinks like the WM9712
    touchscreen driver from getting probed.

    Tested against 2.6.31-rc1.

  • ff637d38e   ASoC: remove stand-alone mode support from CS4270 codec driver ... Browse Code »

    The CS4270 supports stand-alone mode, where the codec is not connect to the
    I2C or SPI buses. Instead, input voltages configure the codec at power-on.
    The CS4270 ASoC device driver has partial support for this mode, but the
    code was never tested, and partial support doesn't help anyone. It also made
    the rest of the code more complicated than necessary.

  • 84bc278b1   ALSA: ASoC: Add OpenFirmware helper for matching bus and codec drivers ... Browse Code »

    Simple utility layer for creating ASoC machine instances based on data
    in the OpenFirmware device tree. OF aware platform drivers and codec
    drivers register themselves with this framework and the framework
    automatically instantiates a machine driver. At the moment, the driver
    is not very capable and it is expected to be extended as more features
    are needed for specifying the configuration in the device tree.

    This is most likely temporary glue code to work around limitations in
    the ASoC v1 framework. When v2 is merged, most of this driver will
    need to be reworked.
