ALSA: hda: Allow for compress stream to hdac_ext_stream assignment

2022-12-05T14:05:18+00:00

Currently only PCM streams can enlist hdac_stream for their data transfer. Add cstream field to hdac_ext_stream to expose possibility of compress stream assignment in place of PCM one. Limited to HOST-type only as there no other users on the horizon.

ASoC: Intel: avs: Introduce PCM power management routines

2022-10-28T12:04:32+00:00

Implement suspend/resume() operations for component drivers. For most scenarios, the PM flow is similar to standard streaming one, except for the part where the position register are being saved and the lack of PCM pages freeing. To reduce code duplication, all avs_dai_suspend_XXX() and avs_dai_resume_XXX() functions reuse their non-PM equivalents. Given that path binding/unbinding happens only in FE part of the stream, the order of suspend() goes: 1. hw_free() all FE DAIs, paths are unbound here 2. hw_free() all BE DAIs Consequently, for resume() its: 1. hw_params() all BE DAIs 2. hw_params() all FE DAIs, paths are bound here 3. prepare() all BE DAIs 4. prepare() all FE DAIs As component->suspend/resume() do not provide substream pointer, store it ourselves so that the PM flow has all the necessary information to proceed.

ALSA/ASoC: hda: move SPIB/DRMS functionality from ext layer

2022-10-20T12:31:42+00:00

The SPIB and DRMS capabilities are orthogonal to the DSP enablement and can be used whether the stream is coupled or not. The existing code partitioning makes limited sense, the capabilities are parsed at the sound/hda level but helpers are located in sound/hda/ext. This patch moves all the SPIB/DRMS functionality to the sound/hda layer. This reduces the complexity of the sound/hda/ext layer which is now limited to handling the multi-link extensions and stream coupling/decoupling helpers. Note that this is an iso-functionality code move and rename, the HDaudio legacy driver would need additional changes to make use of these capabilities.

ALSA/ASoC: hda: ext: add 'bus' prefix for multi-link stream setting

2022-10-20T12:31:41+00:00

All the helpers dealing with multi-link configurations are located in the hdac_ext_controller.c, except the two set/clear routines that modify the LOSIDV registers. For consistency, move the two helpers and add the 'bus' prefix. One could argue that the 'ml' prefix might be more relevant but that would be a larger code change. No functionality change, just move and rename.

ALSA/ASoC: hda: ext: remove 'link' prefix for stream-related operations

2022-10-20T12:31:41+00:00

We should only use 'link' in the context of multi-link configurations. Streams are configured from a different register space and are not dependent on link except for LOSIDV settings. Not functionality change, just pure rename.
