Hi Morimoto-san,
+void snd_soc_stream_stop(struct snd_soc_pcm_runtime *rtd, int stream);
+void snd_soc_stream_stop(struct snd_soc_pcm_runtime *rtd, int stream)
+{
+ if (stream == SNDRV_PCM_STREAM_PLAYBACK) {
+ if (snd_soc_runtime_ignore_pmdown_time(rtd)) {
+ /* powered down playback stream now */
+ snd_soc_dapm_stream_event(rtd,
+ SNDRV_PCM_STREAM_PLAYBACK,
+ SND_SOC_DAPM_STREAM_STOP);
+ } else {
+ /* start delayed pop wq here for playback streams */
+ rtd->pop_wait = 1;
+ queue_delayed_work(system_power_efficient_wq,
+ &rtd->delayed_work,
+ msecs_to_jiffies(rtd->pmdown_time));
+ }
+ } else {
+ /* capture streams can be powered down now */
+ snd_soc_dapm_stream_event(rtd, SNDRV_PCM_STREAM_CAPTURE,
+ SND_SOC_DAPM_STREAM_STOP);
+ }
+}
+EXPORT_SYMBOL_GPL(snd_soc_stream_stop);
I am not a big fan of naming conventions for the new helper. We don't
have any other snd_soc_stream function, but we have a concept of stream
for SoundWire. we also have snd_soc_dapm_stream_ functions..
snd_soc_dapm_stream_stop() maybe?
thanks
-Pierre
