From 2dc0f16b83b43fd1f86a2358d46f46488230c6c8 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 21 Apr 2015 07:02:34 +0000 Subject: ASoC: soc.h: tidyup struct snd_soc_dai_link definition order Current struct snd_soc_dai_link has many members, but definition order was random. Especially, bool / bit field are defined randomly. This patch tidyups these definition order to calculate data alignment easy.

FE: S16_LE/S24_LE BE: S16_LE DPCM can rewrite the format, so basically we don't want to constrain with the BE constraints. But sometimes it will be trouble. This patch adds new .dpcm_merged_format on struct snd_soc_dai_link. DPCM will use FE / BE merged format if .struct snd_soc_dai_link has it. We can have other .dpcm_merged_xxx in the future .dpcm_merged_foramt .dpcm_merged_rate .dpcm_merged_chan Signed-off-by: Kuninori Morimoto Tested-by: Keita Kobayashi Signed-off-by: Mark Brown --- include/sound/soc.h | 3 +++ sound/soc/soc-pcm.c | 47 ++++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 45 insertions(+), 5 deletions(-) (limited to 'include/sound') diff --git a/include/sound/soc.h b/include/sound/soc.h index 38757fe7a3d8..cf63ac1c8968 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -985,6 +985,9 @@ struct snd_soc_dai_link { unsigned int dpcm_capture:1; unsigned int dpcm_playback:1; + /* DPCM used FE & BE merged format */ + unsigned int dpcm_merged_format:1; + /* pmdown_time is ignored at stop */ unsigned int ignore_pmdown_time:1; }; diff --git a/sound/soc/soc-pcm.c b/sound/soc/soc-pcm.c index 35fe58f4fa86..256b9c91aa94 100644 --- a/sound/soc/soc-pcm.c +++ b/sound/soc/soc-pcm.c @@ -1485,30 +1485,67 @@ unwind: } static void dpcm_init_runtime_hw(struct snd_pcm_runtime *runtime, - struct snd_soc_pcm_stream *stream) + struct snd_soc_pcm_stream *stream, + u64 formats) { runtime->hw.rate_min = stream->rate_min; runtime->hw.rate_max = stream->rate_max; runtime->hw.channels_min = stream->channels_min; runtime->hw.channels_max = stream->channels_max; if (runtime->hw.formats) - runtime->hw.formats &= stream->formats; + runtime->hw.formats &= formats & stream->formats; else - runtime->hw.formats = stream->formats; + runtime->hw.formats = formats & stream->formats; runtime->hw.rates = stream->rates; } +static u64 dpcm_runtime_base_format(struct snd_pcm_substream *substream) +{ + struct snd_soc_pcm_runtime *fe = substream->private_data; + struct snd_soc_dpcm *dpcm; + u64 formats = ULLONG_MAX; + int stream = substream->stream; + + if (!fe->dai_link->dpcm_merged_format) + return formats; + + /* + * It returns merged BE codec format + * if FE want to use it (= dpcm_merged_format) + */ + + list_for_each_entry(dpcm, &fe->dpcm[stream].be_clients, list_be) { + struct snd_soc_pcm_runtime *be = dpcm->be; + struct snd_soc_dai_driver *codec_dai_drv; + struct snd_soc_pcm_stream *codec_stream; + int i; + + for (i = 0; i < be->num_codecs; i++) { + codec_dai_drv = be->codec_dais[i]->driver; + if (stream == SNDRV_PCM_STREAM_PLAYBACK) + codec_stream = &codec_dai_drv->playback; + else + codec_stream = &codec_dai_drv->capture; + + formats &= codec_stream->formats; + } + } + + return formats; +} + static void dpcm_set_fe_runtime(struct snd_pcm_substream *substream) { struct snd_pcm_runtime *runtime = substream->runtime; struct snd_soc_pcm_runtime *rtd = substream->private_data; struct snd_soc_dai *cpu_dai = rtd->cpu_dai; struct snd_soc_dai_driver *cpu_dai_drv = cpu_dai->driver; + u64 format = dpcm_runtime_base_format(substream); if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK) - dpcm_init_runtime_hw(runtime, &cpu_dai_drv->playback); + dpcm_init_runtime_hw(runtime, &cpu_dai_drv->playback, format); else - dpcm_init_runtime_hw(runtime, &cpu_dai_drv->capture); + dpcm_init_runtime_hw(runtime, &cpu_dai_drv->capture, format); } static int dpcm_fe_dai_do_trigger(struct snd_pcm_substream *substream, int cmd); -- cgit v1.2.3
