What's this SAI2_MCLK_DIR? Can you provide the description of it?

And why not put it inside:
 +	} else if (of_device_is_compatible(np, "fsl,imx-audio-wm8960")) {
 +		priv->card.set_bias_level = fsl_asoc_card_set_bias_level;

 +		priv->codec_priv.pll_id = WM8960_SYSCLK_AUTO;
 +		priv->dai_fmt |= SND_SOC_DAIFMT_CBM_CFM;

What happens to the codec_dev->name over here so that you need to
specify the name?
