原J721EXCPXEVM扩展板中使用的芯片为PCM3168APAP，在设备树中，此芯片的驱动程序与mscap10共同组成了sound声卡驱动，映射到sound下的j721e-evm.c中，现在音频芯片更换成了TLV320AIC3109，在修改了设备树文件后，是否要修改j721e-evm.c文件来适配该芯片驱动？请问是否有TLV320AIC3109驱动设备树例程可供参考？

已转给e2e工程师，请看下面产品线工程师的回复。Typically dts changes with the corresponding config enabling should be good. I am not the audio expert. I am commenting more from the Linux angle.https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1273708/tda4vm-tlv320aic3109-sound-driver

麻烦请您将下面的dts设备节点代码转发给他浏览：

音频设备的供电是提前给上的，不需要在设备树中指明，I2C通讯正常，请问设备树DTS描述中有哪些错误，请指正
