+ help
+ I2S controller on EP93xx seems to have undocumented HW issue.
+ Underflow of internal I2S controller FIFO could confuse the
+ state machine and the whole stream can be shifted by one byte
+ until I2S is disabled. This option enables IRQ based watchdog
+ which disables and re-enables I2S in case of underflow and
+ fills FIFO with zeroes.
+
+ If you are unsure how to answer this question, answer Y.
