* ASoC: topology: Reenable use from userspaceMark Brown2016-10-11
| | | | | | | | | | | | | | | | | We had inserted a #error into the topology UAPI code to ensure that the ABI was not adopted by userspace while final review and testing was ongoing. The idea was that some finishing touches would be made to the ABI before declaring it stable and suitable for use in production but this has not yet happened as more than a year later revisions to the ABI are still onging. The reality however is that people are shipping topology files in production and these ABI changes are causing practical issues for users and we can't break userspace. This makes this error pointless so we should remove it. Signed-off-by: Mark Brown <broonie@kernel.org> Acked-by: Vinod Koul <vinod.koul@intel.com>
* ASoC: topology: ABI - Add sig_bits to stream capsMengdong Lin2016-08-22

* ASoC: topology: ABI - Add the types for BE DAIMengdong Lin2016-08-08
| | | | | | | | | | | | | | Define the type and ABI struct for Backend DAIs. Add the number of BE DAIs to manifest, and some reserved fields for future extensions. Pump the version number to 5. Topology core will check size of ABI objects to detect version mismatch between user space and kernel.

* ASoC: topology: ABI - Define types for vendor tuplesMengdong Lin2016-03-29
| | | | | | | | | | | | | | | | | | | Tuples, a pair of token and value, can be used to define vendor specific data, for controls and widgets. This can avoid importing binary data blob from other files. Vendor specific tuple arrays will be embeded in the private data buffer of a control or widget object. To be backward compatible, union is used to define the tuple arrays in the existing private data ABI object 'struct snd_soc_tplg_private'. Vendors need to make sure the token values defined by the topology conf file match those defined by their driver. Now supported tuple types are uuid, string, bool, byte, short and word.

| | | | | | | | | | | | | | | | 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.

* Merge tag 'asoc-v4.2-disable-topology' of ↵Takashi Iwai2015-08-19
|\ | | | | | | | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Disable topology support for v4.2 The topology code merged in the v4.2 merge window introduced a new ABI which was believed to be suitable for use but subsequently additional work by the developers of this feature have revealed some problems that need to be addressed. In order to allow this to be done without having to support the initial ABI add Kconfig to disable the build and also add some #error statements to the UAPI header so users can't use them.
| * ASoC: topology: Disable use from userspaceMark Brown2015-08-18
| | | | | | | | | | | | | | | | | | | | Since the topology API is still in sufficient flux for changes to be identified disable the use of the userspace ABI by adding #error statements to the code, ensuring that nobody relies on the headers as currently defined. It is expected that this change will be reverted for v4.3. Signed-off-by: Mark Brown <broonie@kernel.org>

* | ASoC: topology: Update TLV support so we can support more TLV typesMengdong Lin2015-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ASoC: topology: Add topology UAPI headerLiam Girdwood2015-06-03
The ASoC topology UAPI header defines the structures required to define any DSP firmware audio topology and control objects from userspace. The following objects are supported :- o kcontrols including TLV controls. o DAPM widgets and graph elements o Vendor bespoke objects. o Coefficient data o FE PCM capabilities and config. o BE link capabilities and config. o Codec <-> codec link capabilities and config. o Topology object manifest. The file format is simple and divided into blocks for each object type and each block has a header that defines it's size and type. Blocks can be in any order of type and can either all be in a single file or spread across more than one file. Blocks also have a group identifier ID so that they can be loaded and unloaded by ID.
