  • f5f9d7bf6   ASoC: omap-mcpdm: Replace legacy driver ... Browse Code »

    Reasons for the replacement:
    The current driver for McPDM was developed to support the legacy mode only.
    In preparation for the ABE support the current driver stack need the be
    replaced.
    The new driver is much simpler, easier to extend, and it also fixes some of the
    issues with the old stack.

    Main changes:
    - single file for omap-mcpdm (mcpdm.c/h removed)
    - Define names for registers, bits cleaned up, prefixed
    - Full-duplex audio operation (arecord | aplay) has been fixed
    - Less code

    McPDM need to be turned off after all streams has been stopped.
    This might cause pop noise on the output, if the codec's DAC is
    still powered at this time.

    In order to probe, and operate correctly, the OMAP McPDM driver needs to
    be converted to use hwmod.
    The device name has been changed to probe the driver.
    Replace the clk_* with pm_runtime_* calls to manage the clocks correctly.
    Missing request_mem_region/release_mem_region added.

  • b199adfdf   ASoC: omap-mcpdm: Fix threshold and dma configuration ... Browse Code »

    DMA packet_size must be configured based on the McPDM FIFO threshold
    value, number of channels.
    Due to the FIFO operation the DMA muse be configured differently for
    playback, and capture.
    At the same time fix the McPDM threshold values used for playback, and
    capture to avoid broken code.

  • 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().

  • 5f712b2b7   ALSA: ASoC: move dma_data from snd_soc_dai to snd_soc_pcm_stream ... Browse Code »

    This fixes a memory corruption when ASoC devices are used in
    full-duplex mode. Specifically for pxa-ssp code, where this pointer
    is dynamically allocated for each direction and destroyed upon each
    stream start.

    All other platforms are fixed blindly, I couldn't even compile-test
    them. Sorry for any breakage I may have caused.

    [Note that this is a backported version for 2.6.34.

  • db72c2f89   ASoC: OMAP4: Add McPDM platform driver ... Browse Code »

    McPDM platform driver is configured to use sDMA in order to transfer
    to/from memory. Support for interfacing with ABE will be added later.

    McPDM dai currently supports up to 4 downlink channels and 2 uplink
    channels simultaneously, as well as 88.2 and 96 KHz, and a sample
    size of 32 bits.
