Initially, the main purpose of this change was to make the platform optional in the dai_link, instead of inserting the dummy platform driver. This particular case had just been solved by Kuninori Morimoto with commit 1d7689892878 ("ASoC: soc-core: allow no Platform on dai_link"). However, this change may still be useful for those who need multiple platform components on a single dai_link (it solves one of the FIXME note in soc-core) Cc: Kuninori Morimoto Signed-off-by: Jerome Brunet Acked-by: Kuninori Morimoto --- include/sound/soc.h | 6 ++++ sound/soc/soc-core.c | 66 +++++++++++++++++++------------------------- 2 files changed, 34 insertions(+), 38 deletions(-) diff --git a/include/sound/soc.h b/include/sound/soc.h index 64405cdab8bb..4e8071269639 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -997,6 +997,12 @@ struct snd_soc_dai_link { ((i) < link->num_codecs) && ((codec) = &link->codecs[i]); \ (i)++) +#define for_each_link_platforms(link, i, platform) \ + for ((i) = 0; \ + ((i) < link->num_platforms) && \ + ((platform) = &link->platforms[i]); \ + (i)++) + /* * Sample 1 : Single CPU/Codec/Platform * diff --git a/sound/soc/soc-core.c b/sound/soc/soc-core.c index 002ddbf4e5a3..3053a4a461b3 100644 --- a/sound/soc/soc-core.c +++ b/sound/soc/soc-core.c @@ -887,7 +887,7 @@ static int soc_bind_dai_link(struct snd_soc_card *card, struct snd_soc_dai_link *dai_link) { struct snd_soc_pcm_runtime *rtd; - struct snd_soc_dai_link_component *codecs; + struct snd_soc_dai_link_component *dlc; struct snd_soc_component *component; int i; @@ -917,13 +917,14 @@ static int soc_bind_dai_link(struct snd_soc_card *card, /* Find CODEC from registered CODECs */ rtd->num_codecs = dai_link->num_codecs; - for_each_link_codecs(dai_link, i, codecs) { - rtd->codec_dais[i] = snd_soc_find_dai(codecs); + for_each_link_codecs(dai_link, i, dlc) { + rtd->codec_dais[i] = snd_soc_find_dai(dlc); if (!rtd->codec_dais[i]) { dev_info(card->dev, "ASoC: CODEC DAI %s not registered\n", - codecs->dai_name); + dlc->dai_name); goto _err_defer; } + snd_soc_rtdcom_add(rtd, rtd->codec_dais[i]->component); } @@ -931,12 +932,13 @@ static int soc_bind_dai_link(struct snd_soc_card *card, rtd->codec_dai = rtd->codec_dais[0]; /* Find PLATFORM from registered PLATFORMs */ - for_each_component(component) { - if (!snd_soc_is_matching_component(dai_link->platforms, - component)) - continue; + for_each_link_platforms(dai_link, i, dlc) { + for_each_component(component) { + if (!snd_soc_is_matching_component(dlc, component)) + continue; - snd_soc_rtdcom_add(rtd, component); + snd_soc_rtdcom_add(rtd, component); + } } soc_add_pcm_runtime(card, rtd); @@ -1051,22 +1053,22 @@ static int soc_init_dai_link(struct snd_soc_card *card, struct snd_soc_dai_link *link) { int i; - struct snd_soc_dai_link_component *codec; + struct snd_soc_dai_link_component *dlc; - for_each_link_codecs(link, i, codec) { + for_each_link_codecs(link, i, dlc) { /* * Codec must be specified by 1 of name or OF node, * not both or neither. */ - if (!!codec->name == - !!codec->of_node) { + if (!!dlc->name == + !!dlc->of_node) { dev_err(card->dev, "ASoC: Neither/both codec name/of_node are set for %s\n", link->name); return -EINVAL; } /* Codec DAI name must be specified */ - if (!codec->dai_name) { + if (!dlc->dai_name) { dev_err(card->dev, "ASoC: codec_dai_name not set for %s\n", link->name); return -EINVAL; @@ -1076,40 +1078,28 @@ static int soc_init_dai_link(struct snd_soc_card *card, * Defer card registartion if codec component is not added to * component list. */ - if (!soc_find_component(codec)) + if (!soc_find_component(dlc)) return -EPROBE_DEFER; } - /* - * Platform may be specified by either name or OF node, - * or no Platform. - * - * FIXME - * - * We need multi-platform support - */ - if (link->num_platforms > 0) { - - if (link->num_platforms > 1) { - dev_err(card->dev, - "ASoC: multi platform is not yet supported %s\n", - link->name); - return -EINVAL; - } - - if (link->platforms->name && link->platforms->of_node) { + for_each_link_platforms(link, i, dlc) { + /* + * Platform may be specified by either name or OF node, but it + * can be left unspecified, then no components will be inserted + * in the rtdcom list + */ + if (!!dlc->name == !!dlc->of_node) { dev_err(card->dev, - "ASoC: Both platform name/of_node are set for %s\n", + "ASoC: Neither/both platform name/of_node are set for %s\n", link->name); return -EINVAL; } /* - * Defer card registartion if platform dai component is not - * added to component list. + * Defer card registartion if platform component is not added to + * component list. */ - if ((link->platforms->of_node || link->platforms->name) && - !soc_find_component(link->platforms)) + if (!soc_find_component(dlc)) return -EPROBE_DEFER; }
