  • We need to report the entire jack state to the core jack code, not just
    the bits that were being updated by the caller, otherwise the status
    reported by other detection methods will be omitted from the state seen
    by userspace.

  • It is safe to use sleeping gpio in snd_soc_jack_gpio_detect as it is not
    called from interrupt context. This avoids WARN_ON from __gpio_get_value
    if sleeping gpio is registered for jack.

  • As jack detection can trigger DAPM and the latency in debouncing can create
    confusing windows in operation provide some trace events which will hopefully
    help in diagnostics. The soc-jack core traces all reports that it gets and
    the resulting notifications to upper layers. An event for jack IRQs is also
    provided for instrumentation of debounce, and used in the GPIO jack code.

  • If the device associated with a GPIO jack is wakeup capable then disable
    suspend while we're debouncing the jack so that we skip suspends that race
    with the jack.

    Note that currently the GPIO based jack has a CODEC associated with it
    which we're using right now. These jacks should be reparented against the
    card itself and this code adjusted.

  • 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 .

  • Rather than block the workqueue by sleeping to do the debounce use delayed
    work to implement the debounce time. This should also means that we extend
    the debounce time on each new bounce, potentially allowing shorter debounce
    times for clean insertions.

  • 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().

  • Some systems provide both mechanical and electrical detection of jack
    status changes. On such systems power savings can be achieved by only
    enabling the electrical detection methods when physical insertion has
    been detected.

    Begin supporting such systems by providing a notifier for jack status
    changes which can be used to trigger any reconfiguration.

  • The jack_status_check callback function is the interface to check the
    status of the jack. Some target provides the method to distinguish what
    is the jack inserted - headphone jack, microphone jack, tvout jack, etc,
    so we can implement it using the jack_status_check function.

  • If the NULL test on jack is needed, then the derefernce should be after the
    NULL test.

    A simplified version of the semantic match that detects this problem is as
    follows (http://coccinelle.lip6.fr/):

    //
    @match exists@
    expression x, E;
    identifier fld;
    @@

    * x->fld
    ... when != \(x = E\|&x\)
    * x == NULL

  • The patch adds a few small enhancements to the ASoC jack handling, as
    suggested by Mark in his comments to my Amstrad Delta driver, and a few fixes
    for related bugs found while learning Mark's code and testing results.

    Enhancements:
    1. Update status of an ASoC jack while associating it with new gpios.
    2. Really update DAPM pins while associating them with an ASoC jack.
    3. Export ASoC jack gpios over gpiolib sysfs for diagnostic purposes.

    Fixes:
    1. Apply mask on jack status report before using it, just for case.
    2. While updating jack associated DAPM pins, use full resulting jack status,
    not the status report passed as an argument.

    Created and tested on linux-2.6.31-rc3

  • Add GPIO support to jack reporting framework in ASoC using gpiolib calls.
    The gpio support exports two new functions: snd_soc_jack_add_gpios and
    snd_soc_jack_free_gpios.

    Client drivers using gpio feature must pass an array of jack_gpio pins
    belonging to a specific jack to the snd_soc_jack_add_gpios function. The
    framework will request the gpios, set the data direction and request irq.
    The framework will update power status of related jack_pins when an event on
    the gpio pins comes according to the reporting bits defined for each gpio.

    All gpio resources allocated when adding jack_gpio pins can be released
    using snd_soc_jack_free_gpios function.

  • This patch adds a jack reporting interface to ASoC. This wraps the ALSA
    core jack detection functionality and provides integration with DAPM to
    automatically update the power state of pins based on the jack state.

    Since embedded platforms can have multiple detecton methods used for a
    single jack (eg, separate microphone and headphone detection) the report
    function allows specification of which bits are being updated on a given
    report.

    The expected usage is that machine drivers will create jack objects and
    then configure jack detection methods to update that jack.
