The audio card uses loongson I2S controller present in
7axxx/2kxxx chips to transfer audio data.

On loongson platform, the chip has only one I2S controller.

Generic compatible does not allow you to add any quirks or differences
if one board is a bit different.


Yeah, i know. It's okay to use a generic compatible.
