ASoC: soc-core: remove card->dmi_longname

2026-06-04T10:23:46+00:00

Current Card has dmi_longname[80] (when CONFIG_DMI), but no need to have it in Card, we can alloc it. Tidyup it. This is prepare for Card capsuling Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87a4tk2weh.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: soc-card: add snd_soc_card_set_topology_name()

2026-05-28T11:18:29+00:00

Some drivers want to use topology name, but currently each drivers are setting it by own method. This patch adds new snd_soc_card_set_topology_name() and do it by same method. Almost all driver doesn't set topology name, let's remove fixed name array, and use devm_kasprintf() instead.

ASoC: soc-core: Add core support for ignoring suspend on selected DAPM widgets

2026-05-25T12:37:18+00:00

Chancel Liu says: Some audio systems require specific DAPM widgets to remain powered during system suspend. Introduce a generic and reusable mechanism in the ASoC core to mark selected DAPM widgets as ignore_suspend. The unified mechanism consists of two parts: 1. Parse and store the name list of widgets to ignore suspend in struct snd_soc_card The list of widgets can be provided either by the machine driver or parsed from Device Tree. Different machines have different routing and power requirements. Each machine can specify its own widgets to ignore suspend through DT property. It enables flexible policy without hard code. A new helper, snd_soc_of_parse_ignore_suspend_widgets() is added for this purpose. 2. Apply ignore_suspend flags during snd_soc_bind_card() After all components have been probed and all DAPM widgets have been registered, snd_soc_bind_card() performs a unified lookup of the configured widget names across all DAPM contexts of the card and marks the matching widgets with ignore_suspend = 1. Switch to use core ignore-suspend-widgets support for imx-rpmsg driver.

ASoC: move card->pop_time to soc-dapm

2026-05-20T12:36:51+00:00

Kuninori Morimoto says: This is v3 to move card->pop_time to soc-dapm. card->pop_time is used only on TI, and Janusz posted patch which will stop using it. It was posted at 12 Apr 2026, and [1/2] is it as-is. [2/2] will move card->pop_time to soc-dapm. We can use it via debugfs. I have added [RFC] on Subject.

ASoC: soc-dapm: move card->pop_time to soc-dapm.c

2026-05-20T12:36:50+00:00

Card has pop_time which have used only from TI, and it is now stop using it. This pop_time is used for debug, and can be access from debugfs. Let's move it from Card to soc-dapm.c local. This patch renames it as asoc/${card}/pop_time to asoc/dapm_pop_time. This patch moves it from Card to soc-dapm.c, tidyup soc-dapm.c accordingly, and remove card->pop_time from cx20442.c which is no longer needed.

ASoC: core: Move all users to deferrable card binding

2026-05-11T01:06:10+00:00

Commit a3375522bb5e2 ("ASoC: core: Complete support for card rebinding") completed the feature and at the same time divided ASoC users into two groups: 1) cards that fail to enumerate the moment one of the components is not available 2) cards that succeed to enumerate even if some of their components become available late Given the component-based nature of ASoC, approach 2) is preferred and can be used by all ASoC users. By dropping 1) the card binding code can also be simplified. Flatten code that is currently conditional based on ->devres_dev and convert snd_soc_rebind_card() to call_soc_bind_card(). The latter is a selector between managed and unmanaged card-binding behaviour to keep non-devm users happy. With rebinding being the default, devm_snd_soc_register_card() takes form of its deferrable friend - all the devm job is already done by devm_snd_soc_bind_card().
