Interfacing TLV320AIC3254 Audio codec driver

Other Parts Discussed in Thread: TWL6032, TWL6030, TLV320AIC3256

Hi all, 

Based on the e2e forum suggestion from this link --- http://e2e.ti.com/support/data_converters/audio_converters/f/64/t/266169.aspx

we are trying to bring up audio codec in a OMAP4460 board. But during kernel bootup we are getting this error:

[ 2.659423] soc-audio soc-audio: binding Legacy McBSP2 at idx 0
[ 2.659423] soc-audio soc-audio: CPU DAI omap-mcbsp.2 not registered
[ 2.661529] soc-audio soc-audio: CODEC tlv320aic325x-codec not registered
[ 2.661560] soc-audio soc-audio: Registered card 'Tablet44xx'

The way we had initialized the audio machine driver in the kernel is:

/* Digital audio interface glue - connects codec <--> CPU */
static struct snd_soc_dai_link sdp44xx_aic3256_dai[] = {
{
.name = "Legacy McBSP2",
.stream_name = "tlv320aic325x-codec",
.cpu_dai_name ="omap-mcbsp.2", // Mcbsp 2
.codec_dai_name = "tlv320aic325x-MM_EXT",
.platform_name = "omap-pcm-audio",
.codec_name = "tlv320aic325x-codec",
.init = sdp44xx_aic3256_init,
.ops = &sdp44xx_aic3256_ops,
},
};

/* Audio machine driver */
static struct snd_soc_card snd_soc_sdp44xx_aic3256 = {
.name = "Tablet44xx",
.dai_link = sdp44xx_aic3256_dai,
.num_links = ARRAY_SIZE(sdp44xx_aic3256_dai),
.codec_conf = sdp44xx_codec_conf,
.num_configs = ARRAY_SIZE(sdp44xx_codec_conf),
};

Can someone help us on what is being missed in getting through with the registration of the codec and MCBSP interfaces?

Thanks and regards

    Hi, Rajam,

    I hope someone in the community has some tips for you. We do not have experience with this devices and the OMAP4460.

    You may want to investigate approaching one of our Third Parties for help with this issue. You can find a list of OMAP4460 Third parties here.

    Hi 

    After some struggle, we could compile kernel with driver code for the board which initializes the codec and mcbsp interface, However the kernel hangs while booting during the initialization of MMC interface. 

    In the board design, the audio codec is connected to I2C-1 bus in which the PMIC chip TWL6032 is also connected. 

    Here is the snapshot of kernel log where it stops:

    Can we get some help on where the issue might be and suggestions on how to initialize the codec so that the registration and interface of driver with ALSA module gets through for playing the audio? 

    Thanks and regards
