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

2016-11-09T14:46:09Z

User space uses this field to count physical DAIs, not only BE DAIs since users may not use DPCM. So we rename this field from be_dai_elems to dai_elems. This change is backward compatible, because it does not change the layout of the struct or data type. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Add voice wake up flag for DAI links

2016-11-04T17:36:39Z

Add a new flag bit SND_SOC_TPLG_LNK_FLGBIT_VOICE_WAKEUP to link flags. If a link is used for voice wake up, users can set this flag bit and topology will set the link's 'ignore_suspend' to true. This ABI update is backward compatible. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Rename struct and type for physical DAIs

2016-11-04T17:26:42Z

Rename the ABI struct and type because they are for configuring physical DAIs, not only backend DAIs since users may not need DPCM: - Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai. - Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI. This code refactoring is backward compatible because: - Both layout of the struct and type value has no change. Kernel can find the same type value and map to same data layout. - This struct is not in ABI v4 at all. Now the user space uses ABI v4. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Update physical DAI link configuration for version 5

2016-11-04T16:35:26Z

The following fields are added to physical link configuration struct (snd_soc_tplg_link_config) in ABI v5: - name and stream name Topology will use them to find an existing physical link and configure it. - HW configurations Define the types and ABI struct for runtime supported hardware configs of physical DAI links, e.g. audio hardware formats. The default HW config ID will help topology to find the DAI format to set on init. Topology provides this as a fallback if such HW settings are not available in ACPI or device tree, to avoid hard code in drivers. It's only for config items that can be programmed by SW or FW, not for physical things like link connections or GPIO used for HP etc. - flags and private data The flags will be used to configure an existing physical DAI link. The private data is reserved for future extension. NOTE: Current kernel has no support for physical links. A later patch will add support for configuring physical links and make the support backward compatible for ABI v4. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Add flags and private data to PCM

2016-11-03T16:29:02Z

This is the remaining update to PCM ABI object of version 5. The flags will be applied to FE (Front End) links and can also be used by physical links. The private data is reserved for future extension, so offset update will add the private data size. Now user space is using ABI v4, and the previous patch "ASoC: topology: make PCM backward compatible from ABI v4" can assure the backward compatibility.

ASoC: topology: Support topology file of ABI v4

2016-11-03T16:27:57Z

Users start to use topology ABI from v4. ABI v5 updated existing manifest and PCM elements. Two previous patches can support these ABI updates in a backward compatible way. So if the topology file from user space is generated by ABI v4, kernel will no longer quit but continue parsing. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

ASoC: topology: ABI - Define DAI physical PCM data formats

2016-10-21T11:07:03Z

Define DAI physical PCM data formats for user space, so users can configure the formats of backends by topology (e.g. the DAI format to set on backend link init). The kernel will also refer to these formats. Signed-off-by: Mengdong Lin Signed-off-by: Mark Brown

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
