19	  I2S controller on EP93xx seems to have undocumented HW issue.
20	  Underflow of internal I2S controller FIFO could confuse the
21	  state machine and the whole stream can be shifted by one byte
22	  until I2S is disabled. This option enables IRQ based watchdog
23	  which disables and re-enables I2S in case of underflow and
24	  fills FIFO with zeroes.

26	  If you are unsure how to answer this question, answer Y.
