Hi Flavio,
This can be added by yourself. Please read and understand the 'Audio Device Definition Files' segment in the Configurator Help menu. The CC85XX User Guide will come handy when doing this and so does the PCM5310 datasheet with all the register information. When adding support for a new device you will need to understand the volume control portion on the 'Audio Device Definition Files' as well as the state sequences for the audio device (section 3.5.3 in the CC85XX User Guide).
Hope this gets you going and allow you to support this codec.
Regards,
Kjetil
