Compiling a new kernel including audio codec tlv320aic32x4

Hi all.
I’m new in Linux Embedded.
I need to include the firmware, from kernel, linux/sound/soc/codecs/tlv320aic32x4.c to configure a new release, for this audio codec(tlv320aic3204).

Someone, can help me?

Best regards,
Francesco.

It should be already included in the recent Debian distros here:

If you build using these instructions, it's included by default:
