+/* Anomaly notes:
+ * 05000250 - AD1980 is running in TDM mode and RFS/TFS are generated by SPORT
+ * contrtoller. But, RFSDIV and TFSDIV are always set to 16*16-1,
+ * while the max AC97 data size is 13*16. The DIV is always larger
+ * than data size. AD73311 and ad2602 are not running in TDM mode.
+ * AD1836 and AD73322 depend on external RFS/TFS only. So, this
+ * anomaly does not affect blackfin sound drivers.
