+/* 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.
