HI Jon,
In my machine driver , i am not able to create sound card.
/* Digital audio interface glue - connects codec <--> CPU */
static struct snd_soc_dai_link rx51_dai[] = {
{
/* .name = "I2S",
.stream_name = "SUN7I-I2S",
.cpu_dai_name = "sun7i-i2s.0",
.codec_dai_name = "sndi2s",
.init = rx51_aic34_init,
.platform_name = "sun7i-i2s-pcm-audio.0",
.codec_name = "sun7i-i2s-codec.0",
//.dai_fmt = SND_SOC_DAIFMT_DSP_A | SND_SOC_DAIFMT_IB_NF |
// SND_SOC_DAIFMT_CBM_CFM,
.ops = &rx51_ops, */
.name = "TLV320AIC34",
.stream_name = "AIC34",
.cpu_dai_name = "tlv320aic3x-hifi",
.codec_dai_name = "sndi2s",
.init = rx51_aic34_init,
.platform_name = "sun7i-i2s-pcm-audio.0",
.codec_name = "tlv320aic3x-codec.1-0018",
//.dai_fmt = SND_SOC_DAIFMT_DSP_A | SND_SOC_DAIFMT_IB_NF |
// SND_SOC_DAIFMT_CBM_CFM,
.ops = &rx51_ops,
},
};
With first set of configuration i am able to get node file but with second
set of configuration i am not able to get sound card.
if i change tlv320aic3x-hifi and tlv320aic3x-codec.1-0018 by sun7i-i2s.0
and sun7i-i2s-codec.0 respectively then sound card is created.
it means i am passing wrong name, and rx51_aic34_init function also not
calling.
my codec i2c address is 0x18.
i tried writing some bytes into my codec with i2ctools which is fine.
Can you say what i am missing in structure snd_soc_dai_link .
Regards
Punith
