Well, again it depends on your kernel version. If you are using V3.8, you add the audio cape in your uEnv.txt file and you enable the TLV320AIC3x driver in your kernel config. When your kernel boots, it runs the audio codec init which will eventually call the probe function and that will read in the audio cape device tree overlay and configure the audio codec. If you are using a kernel version later than V3.8, you have to manually add the audio cape device tree to your board device tree.
