Public bug reported:
SRU Justification:
[ Impact ]
Some newer audio configurations require SoundWire/SDCA updates for
companion amplifier handling, AMD ACP7.0 Realtek match entries, Lenovo
AMD SoundWire DMIC quirks, combined speaker component naming, and RT722
speaker mute control.
Without these fixes, affected systems may fail to expose the expected
audio topology, DMIC component naming, PCM numbering, or speaker mute
switch needed by userspace/UCM.
[ Fix ]
Backport upstream commits:
- f5cb3ee251b4 ("ASoC: SDCA: Add companion amp Function")
- 7869f1c1123c ("ASoC: amd: acp: Add ACP7.0 match entries for Realtek parts")
- 3acf517e1ae0 ("ASoC: amd: amd_sdw: add machine driver quirk for Lenovo
models")
- 68130eef1e0d ("ASoC: soc-component: re-add pcm_new()/pcm_free()")
- fe33a69681e3 ("ASoC: amd: name back to pcm_new()/pcm_free()")
- 5902e1f3c501 ("ASoC: amd: acp: update dmic_num logic for acp pdm dmic")
- 371f6a1d2a97 ("ASoC: amd: acp-sdw-legacy: rename the dmic component name")
- 3666dc0c47c3 ("ASoC: amd: ps: fix the pcm device numbering for acp pdm dmic")
- 80a7916ca2d9 ("ASoC: amd: acp: add Lenovo P16s G5 AMD quirk for legacy SDW
machine")
- 6b6f7263d626 ("ASoC: amd: acp: update DMI quirk and add ACP DMIC for Lenovo
platforms")
- 87a3f5c8ac20 ("ASoC: sdw_utils: cs42l43: allow spk component names to be
combined")
- bda41dd5e1dd ("ASoC: rt722-sdca: add FU06 Playback Switch for speaker mute
control")
- 8d38c275f7ffe ("ASoC: sdw_utils: remove dai registered check")
[ Test Plan ]
Boot affected hardware and verify:
1. Sound card probes successfully.
2. Expected ALSA PCMs and controls are present.
3. DMIC capture works on affected AMD SoundWire platforms.
4. Speaker playback works.
5. Speaker mute control is exposed and can be toggled by userspace.
[ Where problems could occur ]
The changes affect ASoC SoundWire/SDCA machine matching, component
naming, PCM setup, and RT722 codec mute handling. Regressions could
appear as sound card probe failures, changed component strings affecting
UCM matching, missing or renumbered PCM devices, or incorrect speaker
mute behavior.
