2020-02-24ASoC: soc-pcm: add snd_soc_dai_get_pcm_stream()Kuninori Morimoto
DAI driver has playback/capture stream. OTOH, we have SNDRV_PCM_STREAM_PLAYBACK/CAPTURE. Because of this kind of implementation, ALSA SoC needs to have many verbose code. To solve this issue, this patch adds snd_soc_dai_get_pcm_stream() macro to get playback/capture stream pointer from stream.

2020-02-11ASoC: soc-pcm: call snd_soc_dai_startup()/shutdown() onceKuninori Morimoto
Current soc_pcm_open() calls snd_soc_dai_startup() under loop. Thus, it needs to care about started/not-yet-started codec DAI. But, if soc-dai.c is handling it, soc-pcm.c don't need to care about it. This patch adds started flag to soc-dai.h, and simplify soc-pcm.c. This is one of prepare for cleanup soc-pcm-open() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/875zgfcey5.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
2020-01-21ASoC: soc-core: remove DAI suspend/resumeKuninori Morimoto
Historically, CPU and Codec were implemented different, but now it is merged as Component. ALSA SoC is supporting suspend/resume at DAI and Component level. The method is like below. 1) Suspend/Resume all CPU DAI if bus-control was 0 2) Suspend/Resume all Component 3) Suspend/Resume all CPU DAI if bus-control was 1 Historically 2) was Codec special operation. Because CPU and Codec were merged into Component, CPU suspend/resume has 3 chance to suspend(= 1/2/3), but Codec suspend/resume has 1 chance (= 2). Here, DAI side suspend/resume is caring bus-control, but no driver which is supporting suspend/resume is setting bus-control. This means 3) was never used. Here, used parameter for suspend/resume component->dev and dai->dev are same pointer. For that reason, we can merge DAI and Component suspend/resume. One note is that we should use 2), because it is caring BIAS level. This patch removes 1) and 3).

2019-07-23ASoC: soc-dai: move snd_soc_dai_stream_valid() to soc-dai.cKuninori Morimoto
snd_soc_dai_stream_valid() is function to check stream validity. But, some code is using it, some code are checking stream->channels_min directly. Doing samethings by different method is confusable. This patch uses same funcntion for same purpose.

Sometimes ALSA SoC naming is very random. Current soc_dai_hw_params() should use snd_soc_dai_xxx() style. And then, 1st parameter should be dai.

2019-07-23ASoC: add soc-dai.cKuninori Morimoto
Current ALSA SoC has many snd_soc_dai_xxx() function which is using dai->driver->ops->xxx. But, some of them are implemented as snd_soc_dai_xxx(), but others are directly using dai->driver->ops->xxx. Because of it, the code is not easy to read. This patch creats new soc-dai.c and moves snd_soc_dai_xxx() functions into it. One exception is snd_soc_dai_is_dummy() which is based on soc-utils local variable. We need to keep it as-is there. Others which is directly using dai->driver->ops->xxx will be implemented at soc-dai.c by incremental patches.
