跨平台移植TLV320AIC3X 的音频，求高手进来指点！

硬件平台： 高通芯片mdm96x5  自带音频是wcd9304 和wcd9310   

软件平台： Linux内核3.4.91   yocoto-1.6     需要的是tlv320aic3104

需求： 现在我们需要把TLV320AIC3X 移植在高通上面（需要I2S 和I2C），因为高通的machine里面都是关于wcd9304 和wcd9310的内容。所以现在遇到了问题，以下是我的做法：

1. 找到snd_soc_dai_link 添加 tlv320aic3x的内容，这两行是高通原本的内容，我对应进行了修改（通过I2S控制的部分，但是它分读写的，而我们的snd_soc_dai_link都是一个）

{
.name = LPASS_BE_SEC_I2S_RX,
.stream_name = "Secondary I2S Playback",
.cpu_dai_name = "msm-dai-q6.4",
.platform_name = "msm-pcm-routing",
.codec_name = "tlv320aic3x-codec.0-0018",
.codec_dai_name = "tlv320aic3x-hifi",
.init = &mdm9615_ar7_sec_i2s_audrx_init,
.no_pcm = 1,
.be_id = MSM_BACKEND_DAI_SEC_I2S_RX,
.be_hw_params_fixup = msm9615_i2s_rx_be_hw_params_fixup,
.ops = &msm9615_i2s_be_ops,
},
{
.name = LPASS_BE_SEC_I2S_TX,
.stream_name = "Secondary I2S Capture",
.cpu_dai_name = "msm-dai-q6.5",
.platform_name = "msm-pcm-routing",
.codec_name = "tlv320aic3x-codec.0-0018",
.codec_dai_name = "tlv320aic3x-hifi",
.no_pcm = 1,
.be_id = MSM_BACKEND_DAI_SEC_I2S_TX,
.be_hw_params_fixup = msm9615_i2s_tx_be_hw_params_fixup,
.ops = &msm9615_i2s_be_ops,
},

2. 除了machine 里的修改  还有就是在arch/arm/mach-msm里进行I2C 的硬件配置。

红色两个successful是我自己加的，I2C 没问题，可以看到进去了 aic3x_probe里了 但是出错了，是就卡在这里了，板子就没有起来。

想问问高手们对于machine来说 我只需要改codec_name 和codec_dai_name 就可以了吗？ 因为它这里面有别的音频的配置，那些我是不是就不需要管了呢？

板子会启用这个snd_soc_dai_link ：
