[PATCHv4 4/9] ASoC: fsl-asoc-card: add new compatible for a generic codec use case
by Elinor Montmasson 15 May '24

15 May '24

Add the new compatible "fsl,imx-audio-generic" for a generic codec use case. It allows using the fsl-asoc-card driver with the spdif_receiver and spdif_transmitter codec drivers used as dummy codecs. It can be used for cases where there is no real codec or codecs which do not require declaring controls.

[PATCHv4 3/9] ASoC: fsl-asoc-card: add compatibility to use 2 codecs in dai-links
by Elinor Montmasson 15 May '24

15 May '24

Adapt the driver to work with configurations using two codecs or more. Modify fsl_asoc_card_probe() to handle use cases where 2 codecs are given in the device tree. This will be needed for the generic codec case. Use cases using one codec will ignore any given codecs other than the first.

[PATCHv4 2/9] ASoC: fsl-asoc-card: add second dai link component for codecs
by Elinor Montmasson 15 May '24

15 May '24

Add a second dai link component for codecs that will be used for the generic codec use case. It will use spdif_receiver and spdif_transmitter drivers as dummy codec drivers, needing 2 codecs slots for the links. To prevent deferring in use cases using only one codec, also set by default the number of codecs to 1 for the relevant dai links.

[PATCH v2 0/3] ASoC: grace time for DPCM cleanup
by Kuninori Morimoto 15 May '24

15 May '24

Hi Mark, Pierre-Louis, Jerome Cc each ASoC driver maintainer As we discussed in [1], we don't need to use dpcm_playback/capture flag, so we remove it. But we have been using it for 10 years, some driver might get damage. The most likely case is that the device/driver can use both playback/capture, but have only one flag, and not using xxx_only flag. [1/3] patch indicates warning in such case. And because of its history, DPCM has been checking CPU side only. But it should check Codec side too same as non-DPCM. Some device/driver has been bypassed this check. It should be error. [2/3] patch indicates warning in such case. Because dpcm_xxx flag is no longer used by [1/3] patch, snd_soc_dai_link_set_capabilities() is no longer needed. [3/3] patch remove it. These adds grace time for DPCM cleanup. I'm not sure when dpcm_xxx will be removed, and Codec check bypass will be error, but maybe v6.11 or v6.12 ? Please check each driver by that time.

[PATCH] ASoC: rt711-sdca: add GE selected mode control
by shumingf＠realtek.com 15 May '24

15 May '24

From: Shuming Fan <shumingf(a)realtek.com> The SDCA spec defines a 'selected_mode' control which can override the 'detected_mode' reported by hardware. This is useful for platform integration as well as in cases where the hardware is not able to accurately detect the jack type.

Then change one of the controls, I tried the "Z Test Volume" that gets numid 4: `amixer -D hw:0 cset numid=4 5` This generates and event, which runs the callback function.
