[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series consists of two patches to handle the below issues observed
when testing with slave mode:
  + The coalesced stop condition with the start conditions
  + Early ack'ed of Tx done (ACK and NAK) causing "Unexpected Ack on
  read request".

This series was verified with ast2500 and ast2600.
