To support multiple cpu DAIs, add cpu_dai and num_cpu_dai in snd_soc_dai_link and snd_soc_pcm_runtime structures similar to support for codec_dai. Inline with multiple codec DAI approach, add support to allocate, init, bind and probe multiple cpu_dai on init if driver specifies that. Also add support to loop over multiple cpu_dai during suspend and resume Signed-off-by: Shreyas NC Signed-off-by: Vinod Koul --- include/sound/soc.h | 6 ++ sound/soc/soc-core.c | 283 +++++++++++++++++++++++++++++++++++---------------- 2 files changed, 201 insertions(+), 88 deletions(-) -- 2.7.4 _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel diff --git a/include/sound/soc.h b/include/sound/soc.h index ad266d7e9553..f7ce7ec44396 100644 --- a/include/sound/soc.h +++ b/include/sound/soc.h @@ -1060,6 +1060,9 @@ struct snd_soc_dai_link { struct snd_soc_dai_link_component *codecs; unsigned int num_codecs; + struct snd_soc_dai_link_component *cpu_dai; + unsigned int num_cpu_dai; + /* * You MAY specify the link's platform/PCM/DMA driver, either by * device name, or by DT/OF node, but not both.
