commit f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support") has replaced "card->pmdown_time" to "rtd->pmdown_time". card->pmdown_time has been not used this 15 years. Let's remove it. Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87eckstz49.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: cs35l56: Support for factory calibration through ALSA controls

2026-03-26T10:20:46+00:00

Richard Fitzgerald says: Factory calibration is normally done through debugfs files. Google have requested that factory calibration can be performed by repair shops. These repair shops only have access to the standard "user" kernel, which does not include debugfs. Patch #1 adds a new control definition macro to create a boolean control with specified access permissions. (new in V2) Patch #2 is the implementation in the cs35l56 driver.

ASoC: soc.h: Add SOC_SINGLE_BOOL_EXT_ACC() to allow setting access flags

2026-03-26T10:20:43+00:00

Add a macro SOC_SINGLE_BOOL_EXT_ACC() to allow the access permission flags to be set. This is the same as SOC_SINGLE_BOOL_EXT() but with an extra argument for the access flags.

ASoC: partial match the sdca codec name

2026-03-02T13:35:04+00:00

Merge series from Bard Liao : Currently, we set a predefined codec component name in a DAI link. But the codec name may contain an index which is not fixed. This series suggest using partial match the codec name to fix the issue.

SDCA Improvements

2026-02-27T01:13:41+00:00

Merge series from Charles Keepax : Another fairly mixed bag of small SDCA fixes/improvements. Fix one DisCo property that was treated as mandatory but is actually not present in the first version of the specification. Fix the counting of routes for SU/GE DAPM widgets, this currently makes assumptions that are not guaranteed to be true which can result in too many/few DAPM routes. Then finally a couple improvements to the volume controls, simplify the mapping between ALSA and SDCA volumes and pull the volume stuff back into the SDCA code. It just wasn't sitting right with me that it was being handled in the ASoC core given it is unlikely to ever see any reuse outside of SDCA.

ASoC: SDCA: Pull the Q7.8 volume helpers out of soc-ops

2026-02-26T19:16:48+00:00

It is cleaner to keep the SDCA code contained and not update the core code for things that are unlikely to see reuse outside of SDCA. Move the Q7.8 volume helpers back into the SDCA core code.
