[PATCH] ASoC: SOF: sof-audio: add support for setting up topology loopback routes
by Peter Ujfalusi 07 Mar '23

07 Mar '23

From: Chao Song <chao.song(a)linux.intel.com> During route setup, playback stream routes are setup by going through sink path, capture stream routes are set up by going through source path. This is not sufficient to handle loopback cases between pipelines configured with different directions, e.g. a sidetone or an amplifier feedback connected to a speaker protection module. So, add the logic to handle such routes between widgets that aren't in the list of DAPM widgets associated with the same PCM.

[PATCH] ASoC: soc-core.c: remove useless dev_dbg()
by Kuninori Morimoto 06 Mar '23

06 Mar '23

soc-core.c is using dev_dbg(), but some of them are useless. It indicates many dev_dbg() at snd_soc_runtime_get_dai_fmt(), but all of them are just noise, almost no meanings. dev_dbg() on soc_probe_link_dais() indicates dai link and its loop order, but it is just noise, no information. dev_dbg() on snd_soc_register_dai() is duplicated. This patch cleanup these.

[PATCH v7 0/4] Add CS35L41 shared boost feature
by Lucas Tanure 06 Mar '23

06 Mar '23

Valve's Steam Deck uses CS35L41 in shared boost mode, where both speakers share the boost circuit. Add this support in the shared lib, but for now, shared boost is not supported in HDA systems as would require BIOS changes. Based on David Rhodes shared boost patches. Also, fix boost config overwriting in IRQ found in the review and do a small refactor of the code. Changes from V6: - Fix TX/RX bits in passive amp Changes from V5: - Improved documentation from Cirrrus - All amps use MDSCYN for boost source - Active amp has TX and RX enabled Changes from V4: - Fix Document subject Changes from V3: - Fix wrong code sent - Fix ISO C90 mixed declarations and code Changes from V2: - Drop External boost without VSPK Documentation - Move Shared boost to use values 2 and 3 - Revert back to reg_sequence but reading the value first and only update the necessary bits - Fix bug found by Intel kernel Test Robot Changes from V1: - Fix Documentation patch subject - New patch for External boost without VSPK Documentation - New patch to fix boost IRQ overwriting issue - New patch to refactor IRQ release error code - reinit_completion on pcm_startup - fix DRE switch overwriting - return IRQ_HANDLED in PLL_LOCK case Lucas Tanure (4): ASoC: cs35l41: Only disable internal boost ASoC: cs35l41: Refactor error release code ALSA: cs35l41: Add shared boost feature ASoC: dt-bindings: cirrus,cs35l41: Document CS35l41 shared boost .../bindings/sound/cirrus,cs35l41.yaml | 10 +- include/sound/cs35l41.h | 13 +- sound/pci/hda/cs35l41_hda.c | 6 +- sound/soc/codecs/cs35l41-lib.c | 73 +++++++++- sound/soc/codecs/cs35l41.c | 125 +++++++++--------- sound/soc/codecs/cs35l41.h | 1 + 6 files changed, 157 insertions(+), 71 deletions(-) -- 2.39.2

[PATCH v7 00/10] Add the PowerQUICC audio support using the QMC
by Herve Codina 06 Mar '23

06 Mar '23

Hi, This series adds support for audio using the QMC controller available in some Freescale PowerQUICC SoCs. This series contains three parts in order to show the different blocks hierarchy and their usage in this support. The first one is related to TSA (Time Slot Assigner). The TSA handles the data present at the pin level (TDM with up to 64 time slots) and dispatchs them to one or more serial controller (SCC). The second is related to QMC (QUICC Multichannel Controller). The QMC handles the data at the serial controller (SCC) level and splits again the data to creates some virtual channels. The last one is related to the audio component (QMC audio). It is the glue between the QMC controller and the ASoC component. It handles one or more QMC virtual channels and creates one DAI per QMC virtual channels handled.
