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

2025-11-20T16:04:20+00:00

Add a macro SND_SOC_BYTES_E_ACC() to allow the access permission flags to be set. This is the same as SND_SOC_BYTES_E() but with an extra argument for the access flags. This will be used by the cs35l56.c driver to create a read-only volatile byte control. It's preferable to avoid custom control macros in codec drivers. Code maintenance is easier if all control macros are defined together in soc.h. This commit only creates this one macro that is actually going to be used. There's no point cluttering soc.h with unused macros - that just adds a maintenance burden. People can add equivalents for the other macros if they need them.

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

2025-11-20T16:04:19+00:00

Add a macro SOC_ENUM_EXT_ACC() to allow the access permission flags to be set. This is the same as SOC_ENUM_EXT() but with an extra argument for the access flags. This will be used by the cs35l56.c driver to create a read-only volatile enum. It's preferable to avoid custom control macros in codec drivers.

ASoC: SDCA: support Q7.8 volume format

The SDCA specification uses Q7.8 volume format. This patch adds a field to indicate whether it is SDCA volume control and supports the volume settings.

ASoC: soc.h: remove snd_soc_kcontrol_component()

All driver is now using snd_kcontrol_chip() instead of snd_soc_kcontrol_component() to get component. Remove snd_soc_kcontrol_component(). Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/87bjmam7jf.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: soc-card: add snd_soc_card_to_dapm()

2025-09-18T21:24:13+00:00

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. Current dapm of card/component are using "instance", but it will be "pointer" if snd_soc_dapm_context was removed from header. snd_soc_card_to_dapm() is needed to switch to the new style while maintaining compatibility Signed-off-by: Kuninori Morimoto Link: https://patch.msgid.link/877byex06i.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: soc-core: merge snd_soc_unregister_component() and snd_soc_unregister_component_by_driver()

2025-05-12T12:09:44+00:00

We have below 2 functions, but these are very similar (A) snd_soc_unregister_component_by_driver() (B) snd_soc_unregister_component() (A) void snd_soc_unregister_component_by_driver(...) { ... (a) mutex_lock(&client_mutex); ^ (X) component = snd_soc_lookup_component_nolocked(dev, component_driver->name); | if (!component) ^^^^^^^^^^^^^^^^^^^^^^ | goto out; (b) | snd_soc_del_component_unlocked(component); v out: (c) mutex_unlock(&client_mutex); } (B) void snd_soc_unregister_component_by_driver(...) { (a) mutex_lock(&client_mutex); ^ while (1) { | (X) struct snd_soc_component *component = snd_soc_lookup_component_nolocked(dev, NULL); | ^^^^ (b) if (!component) | break; | | snd_soc_del_component_unlocked(component); v } (c) mutex_unlock(&client_mutex); } Both are calling lock (a), find component and remove it (b), and unlock (c). The big diff is whether use driver name for lookup() or not (X). Merge these into snd_soc_unregister_component_by_driver() (B), and snd_soc_unregister_component_by_driver() (A) can be macro.
