ASoC: soc-dapm: add snd_soc_dapm_set_idle_bias()

2025-09-18T21:24:18Z

Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Many drivers are directly setting dapm->idle_bias, but it will be impossible soon. adds snd_soc_dapm_set_idle_bias() for them.

ASoC: soc-dapm: add snd_soc_dapm_get_bias_level()

2025-09-18T21:24:17Z

Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Many drivers are directly using dapm->idle_bias, but it should get it via get_idle_bias() function. Makes it as global function.

ASoC: soc-dapm: tidyup idle_bias handling - step1

2025-09-18T21:24:15Z

Current soc-dapm is using "idle_bias_off", and its default settings came from snd_soc_component "idle_bias_on". It is complicated/confusable. Let's handling it as "idle_bias".

ASoC: soc-dapm: remove suspend_bias_off from snd_soc_dapm_context

2025-09-18T21:24:14Z

We can directly use suspend_bias_off via snd_soc_component, no need to keep it on dapm. Remove it. Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/875xdyx06e.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: soc-dapm: use dapm->component instead of container_of()

2025-09-18T21:24:11Z

Because struct snd_soc_dapm_context is soc-dapm framework specific, user driver don't need to access its member directly, we would like to hide them. struct snd_soc_dapm_context will be removed from header in the future. Now, snd_soc_dapm_to_component() (A) will convert dapm to component by container_of() (a). (A) static inline struct snd_soc_component *snd_soc_dapm_to_component( struct snd_soc_dapm_context *dapm) { (a) return container_of(dapm, struct snd_soc_component, dapm); } dapm of component works, but dapm of card will be "unknown" pointer (= not NULL), because (a) is using "container_of()". OTOH, ASoC will call snd_soc_dapm_init() (X) to initialize dapm, and it will be called from snd_soc_bind_card() (p) (for card) or soc_probe_component() (q) (for component) with component pointer. (p) static int snd_soc_bind_card(...) { ... (X) snd_soc_dapm_init(..., NULL); ... ^^^^ } (q) static int soc_probe_component(...) { ... (X) snd_soc_dapm_init(..., component); ... ^^^^^^^^^ } And snd_soc_dapm_init() (X) will fill dapm->component (x) (X) void snd_soc_dapm_init(..., component, ...) { ... (x) dapm->component = component; ... } We can simply use dapm->component in snd_soc_dapm_to_component() (A). In this case, dapm of card (p) will be just NULL. Use dapm->component instead of container_of(). The picky note can be removed by this patch.

ASoC: soc-dapm: rename snd_soc_kcontrol_component() to snd_soc_kcontrol_to_component()

2025-09-01T12:37:59Z

We have 2 similar functions, both converts date from snd_kcontrol to snd_soc_component. (A) snd_soc_kcontrol_component() (B) snd_soc_dapm_kcontrol_component() (A) is just wrapper for snd_kcontrol_chip(). (B) is for more complex conversion. Having similar functions is confusable. So (A) will be replaced to original snd_kcontrol_chip(). (B) will be stay, but the function name should be xx_to_xx(). And it is defined at soc-component.h. It should be implemented at soc-dapm.c. This patch renames it to snd_soc_dapm_kcontrol_to_component(), and move to soc-dapm.c. This patch keeps compatible by using define, but old name will be replaced on each drivers and removed from ASoC in the future.

2025-09-01T12:37:57Z

snd_soc_dapm_kcontrol_dapm() is unclear naming, rename it to snd_soc_dapm_kcontrol_to_dapm(). This is prepare for dapm cleanup.
