ASoC: topology: Reenable use from userspace

2016-10-11T09:59:18Z

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 Acked-by: Vinod Koul

ASoC: topology: ABI - Add sig_bits to stream caps

2016-08-22T17:55:30Z

Kernel struct snd_soc_pcm_stream, SoC PCM stream information, needs this field. Although current topology users don't configure this, we define it for future extension. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Add the types for BE DAI

2016-08-08T10:55:27Z

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. Signed-off-by: Guneshwor Singh Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: Set the link ID when creating a FE DAI link

2016-04-20T16:16:49Z

Topology will set the link's generic id when creating a FE link. Device drivers can check the id for link specific initialization. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Define types for vendor tuples

2016-03-29T18:44:05Z

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.

ASoC: topology: ABI - Rename dai_elems to pcm_elems in manifest

2015-11-16T10:17:17Z

This field is the number of PCM objects (a pair of FE DAI and DAI link). Signed-off-by: Lin Mengdong Signed-off-by: Mark Brown

ASoC: topology: ABI - Remove tdm_slot & dai_fmt from snd_soc_tplg_stream

2015-10-02T16:59:50Z

These two fields are line parameters for BE/CC links and should not be from toplogy but from ACPI. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Add configuration for BE & Codec-Codec DAI Links

2015-10-02T16:59:49Z

struct snd_soc_tplg_link_config is defined to configure BE & CC links. Signed-off-by: Vedang Patel Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Add the type for BE DAI link

2015-10-02T16:59:49Z

Define the topology type for BE DAI link: SND_SOC_TPLG_TYPE_BACKEND_LINK. Signed-off-by: Vedang Patel Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Change stream formats to a bitwise flag

2015-10-02T16:59:49Z

The toplogy user space tool will generate this bitwise flag by using SNDRV_PCM_FORMAT_* exposed by asound.h, and the topology core will copy this flag when generating DAI streams. Signed-off-by: Mengdong Lin Acked-by: Liam Girdwood Signed-off-by: Mark Brown
