2016-05-05ASoC: topology: Fix memory leak in widget creationJeeja KP1-0/+2
name and sname allocated in widget create are not freed when creation is successful, so free them. Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-04-27ASoC: topology: Check size mismatch of ABI objects before parsingMengdong Lin1-2/+29
If size mismatch of manifest, ABI headers or elements is found, stop parsing topology info and return the error. New fields may be append to the tail of ABI objects which will cause object size to increase. If user space and kernel use different versions of ABI, size mismatch will be detected here.

We are getting build warning about: sound/soc/soc-topology.c:249:31: warning: 'get_dobj_type' defined but not used commit 64527e8a3529 has removed the only caller of get_dobj_type() but missed to remove the function which is now unused. And after removing get_dobj_type() we do not have any use of get_dobj_mixer_type().

2016-02-15ASoC: topology: Add FE DAI links dynamicallyMengdong Lin1-1/+69
Topology will also create FE DAI links dynamically from the PCM objects. These links will be removed when the component is removed and its topology info is unloaded. The component driver can implement link_load/unload ops for extra intialization (e.g. error check) and destruction.

2016-02-15ASoC: topology: Add FE DAIs dynamicallyMengdong Lin1-42/+87
Topology will create FE DAIs dynamically from the PCM objects, and register them to the component. A PCM topoplogy object describes a FE DAI and DAI link. Later patch will add FE DAI links as well. Change tplg load ops for DAI: - Only process a DAI. - Pass the DAI driver pointer to the component driver for extra initialization.

2015-11-10ASoC: dapm: Reset dapm wcache after freeing damp widgetsJyri Sarha1-0/+1
If there is anything in damp->path_source_cache or damp->path_sink_cache, it can not be valid after the widgets have been freed. Without this patch a repeated remove and load of a machine driver may cause NULL pointer reference in dapm_wcache_lookup() when a freed widget, not belonging to any list, is haunting in the wcache.

2015-10-02ASoC: topology: ABI - Add PCM Support and bump ABI version to 4Vedang Patel1-2/+2
The struct snd_soc_tplg_pcm_dai is renamed to snd_soc_tplg_pcm. This struct will now be used to handle data related to PCMs (FE DAI & DAI links). It's not for BE, because BE DAI mappings will be provided by ACPI/FDT data. Remove the unused struct snd_soc_tplg_pcm_cfg_caps. We are using snd_soc_tplg_stream and snd_soc_stream_caps instead.

2015-08-21ASoC: topology: Add support for TLV bytes controlsMengdong Lin1-3/+39
Allow vendor drivers to define bespoke bytes ext handlers and IDs for TLV bytes controls. And the topology core will bind these handlers by matching IDs defined by the vendor driver and user space topology data file. And TLV callback binding is moved to soc_tplg_kcontrol_bind_io(). This function process all handler binding now. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-08-06ASoC: topology: Update TLV support so we can support more TLV typesMengdong Lin1-17/+41
Currently the TLV topology structure is targeted at only supporting the DB scale data. This patch extends support for the other TLV types so they can be easily added at a later stage. TLV structure is moved to common topology control header since it's a common field for controls and can be processed in a general way. Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct. Added TLV structure to generic control header and removed TLV structure from mixer control.

2015-07-21ASoC: dapm: Add helper function to free a widgetLars-Peter Clausen1-24/+1
snd_soc_tplg_widget_remove_all() has a verbatim copy of an older version of the widget freeing code from dapm_free_widgets(). Add a new helper function that takes care of freeing a widget and use it in both places. This removes the duplicated code and also makes sure that future changes to the widget freeing code only have to be made in one location.

2015-06-04ASoC: topology: Add topology coreLiam Girdwood1-0/+1826
The topology core parses the FW topology file for known block types and instanciates any common ALSA/ASoC objects that it discovers. The core also passes any block that is does not understand to client component drivers for enumeration. The core exports some APIs to client drivers in order to load and unload firmware topology data as use case require. Currently the core deals with the following object types :- o kcontrols. This includes TLV, enumerated and bytes controls. o DAPM widgets. All types with any associated kcontrol. o DAPM graph. o FE PCM. FE PCM capabilities and configuration can be defined. o BE DAI Link. BE DAI link capabilities and configuration can be defined. o Codec <-> codec style links capabilities and configuration.
