Thus, I specifiy the codec in machine driver directly. If the codec is changed, there will be a new sound card and binding file. In conclusion, the codec won't be updated via dts, and that's why I don't just replace ADDA_BE in this binding. Do you suggest me add some information in the commit message? Thanks, Trevor
