2016-12-12ASoC: topology: avoid uninitialized kcontrol_typeArnd Bergmann1-0/+1
When num_kcontrols is zero, widget->dobj.widget.kcontrol_type gets set to an uninitialized local variable: sound/soc/soc-topology.c: In function 'soc_tplg_dapm_widget_create': sound/soc/soc-topology.c:1566:36: error: 'kcontrol_type' may be used uninitialized in this function [-Werror=maybe-uninitialized] I could not figure out which of the valid types would be appropriate here, so this sets it to '0', which is invalid but at least well-defined here. There is probably a better way to address the issue.

2016-12-05ASoC: topology: Only free TLV for volume mixers of a widgetMengdong Lin1-8/+17
This patch will check the type of embedded controls for a widget, and only free the TLV of volume mixers. Bytes controls don't have TLV. Just free the private value which is used as struct soc_mixer_control for volume mixers or soc_bytes_ext for bytes controls. No need to cast to these types before freeing it.

2016-12-05ASoC: topology: Allow a widget to have multiple enum controlsMengdong Lin1-76/+87
This patch can create multiple enumerated mixer controls for a widget. Previously topology kernel driver assumes a widget can have only one emumerated mixer control. We need to remove this restriction for Broxton. Its firmware modules (widgets) may need multiple enum controls based on the channel and MIC combination. No ABI change is needed. The ABI allows a widget to embed multiple controls.

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 <mengdong.lin@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-11-04ASoC: topology: Rename functions & variables for physical DAIsMengdong Lin1-28/+29
Code refactoring. These functions and variables are for configuring physical DAIs, not only backend DAIs since users may not need DPCM.

2016-11-04ASoC: topology: ABI - Rename struct and type for physical DAIsMengdong Lin1-4/+4
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.

2016-11-03ASoC: topology: ABI - Add flags and private data to PCMMengdong Lin1-2/+26
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.

User space may not always set a valid FE DAI driver's name, FE DAI link's name, stream name or cpu DAI name. In such cases, there are all ZERO in these name string buffers of a topology PCM object.

2016-11-03ASoC: topology: Make PCM backward compatible from ABI v4Mengdong Lin1-12/+133
This patch adds support for old version 4 of PCMs (FE DAI & DAI links). Topology ABI v5 added new fields to stream caps and thus changed PCMs. Since user space may still uses v4, kernel will check the ABI version by comparing the object size. If user space uses v4 of PCMs, kernel will create the latest version of PCMs from the old version, and use the new version internally to create FE DAI & DAI links. Because these new created PCM elements will be freed later, kernel need duplicate the name strings of DAI driver and DAI links when creating them.

2016-10-28ASoC: topology: Make manifest backward compatible from ABI v4Mengdong Lin1-8/+79
This patch adds support for old version 4 of manifest. Topology ABI v5 added new fields to manifest while user space may still uses v4. So kernel will check the ABI version by comparing the object size.

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.
