Hello all,
We are working on a custom board based on tda2sx.We are trying to interface tlv320aic34 through mscap4 and mcasp7.The codec is being deteced as i2c device but I'm getting the followig log:
asoc-simple-card sound@0: tlv320adc3101-hifi <-> 48474000.mcasp mapping ok
tlv320aic3x-codec 2-001a: ASoC: Failed to set DAI format: -22
asoc-simple-card sound@1: tlv320aic3x-hifi <-> 48478000.mcasp mapping ok
tlv320aic3x-codec 2-001b: ASoC: Failed to set DAI format: -22
asoc-simple-card sound@2: tlv320aic3x-hifi <-> 4846c000.mcasp mapping ok
Why is its failing to set DAI format?I made the following modification in davinci-evm.c
static struct snd_soc_dai_link evm_dai_tlv320aic3x = {
.name = "TLV320AIC3X",
.stream_name = "AIC3X",
.codec_dai_name = "tlv320aic3x-hifi",
.ops = &evm_ops,
.init = evm_aic3x_init,
/*.dai_fmt = SND_SOC_DAIFMT_DSP_B | SND_SOC_DAIFMT_CBM_CFM |
SND_SOC_DAIFMT_IB_NF,*//*commented by murugan.s@fossilshale.com*/
/* .dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBM_CFM |
SND_SOC_DAIFMT_IB_NF,*/
.dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBS_CFS | SND_SOC_DAIFMT_NB_NF,
};
