  • 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 .

  • Now soc-cache.c can figure out the I2C and SPI control data from the
    device for the CODEC we don't need to manually assign it in drivers.

  • 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().

  • One of the features of the multi CODEC work is that it embeds a struct
    device in the CODEC to provide diagnostics via a sysfs class rather than
    via the device tree, at which point it's much better to use the struct
    device private data rather than having two places to store it. Provide
    an accessor function to allow this change to be made more easily, and
    update all the CODEC drivers are updated.

    To ensure use of the accessor the private data structure member is
    renamed, meaning that if code developed with older an older core that
    still uses private_data is merged it will fail to build.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • snd_soc_init_card() is always called as the last part of the CODEC probe
    function so we can factor it out into the core card setup rather than
    have each CODEC replicate the code to do the initialiastation. This will
    be required to support multiple CODECs per card.

  • More and more devices feature PLLs and FLLs with the ability to select
    between multiple input clocks. In order to better support these devices
    a new argument, source, has been added to the set_pll() configuration
    API. Using set_clkdiv() is often difficult due to the need to stop the
    PLL/FLL before any reconfiguration can be done.

  • 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.

  • Many codec drivers were implementing cookie-cutter copies of the function
    that adds kcontrols to the codec.

    This patch moves this code to a common function snd_soc_add_controls() in
    soc-core.c and updates all drivers using copies of this function to use the
    new common version.

  • Currently this is done at module probe time since ASoC ties in codec
    device probe to the instantiation of the entire ASoC device. Subsequent
    patches will refactor the codec drivers to handle probing separately.
    Note that the core does not yet use this information.

    AC97 is special since the codec is controlled over the AC97 link but
    we want to give the machine driver a chance to set up the system before
    trying to instantiate since it may need to do configuration before the
    AC97 link will operate

  • Liam Girdwood's ASoC v2 work avoids having two different ops structures
    for DAIs by merging the members of struct snd_soc_ops into struct
    snd_soc_dai_ops, allowing per DAI configuration for everything.
    Backport this change.

    This paves the way for future work allowing any combination of DAIs to
    be connected rather than having fixed purpose CODEC and CPU DAIs and
    only allowing CODECCPU interconnections.

  • Currently the boiler plate code used by most ASoC codecs to provide a
    placeholder for SPI access suggests making the selection of SPI a
    compile time option which is suboptimal when trying to build kernels
    supporting multiple systems. Change this template to suggest allowing
    runtime selection instead.

    Leave the drivers not yet converted to new style I2C access for now to
    avoid collisions.
