ASoC: use snd_kcontrol_chip() instead of

2025-10-21T18:05:28Z

Merge series from Kuninori Morimoto : We would like to hide struct snd_soc_dapm_context from driver. So we need cleanup code first. Current ASoC have very similar functions (A)(B). (A) snd_soc_kcontrol_component() (B) snd_soc_dapm_kcontrol_component() (B) is using very picky way to get component but using it is necessary in ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly using it without wrapper is very common way on ALSA. This patch-set doesn't merge patches for each vender etc, because it makes backport difficult.

ASoC: codecs: aw88399: use snd_kcontrol_chip() instead of snd_soc_kcontrol_component()

2025-10-20T01:42:28Z

We have very similar name functions (A)(B). Both gets component from snd_kcontrol, but (A) is used in callback functions which is registered through snd_soc_add_component_controls(), (B) is used through snd_soc_dapm_new_widgets(). (A) snd_soc_kcontrol_component() (B) snd_soc_dapm_kcontrol_component() (B) is using very picky way to get component but using it is necessary in ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly using it without wrapper is very common way on ALSA. To reduce confusions of similar function, let's use common way on (A).

ASoC: replace use of system_wq with system_dfl_wq

2025-10-15T09:47:31Z

Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. system_wq is a per-CPU worqueue, replaced by system_percpu_wq. Despite that, system_wq in this change has been replaced by system_dfl_wq, because there aren't per-cpu variables. The old wq will be kept for a few release cylces.

ASoC: codecs: Call strscpy() with correct size argument

2025-08-12T11:05:56Z

In aw8xxxx_profile_info(), strscpy() is called with the length of the source string "null" rather than the size of the destination buffer. This is fine as long as the destination buffer is larger than the source string, but we should still use the destination buffer size instead to call strscpy() as intended. And since 'name' points to the fixed-size buffer 'uinfo->value.enumerated.name', we can safely omit the size argument and let strscpy() infer it using sizeof() and remove 'name'.

ASoC: codecs: Add calibration function to aw88399 chip

2025-06-29T21:12:12Z

Add calibration functionality to the aw88399 chip. When the chip is in calibration condition, calibration can be achieved by configuring the chip's internal DSP and save the calibration values in cali_re.
