   4 Subject: [PATCH] MLK-13609: ASoC: fsl_sai: fix for synchronize mode
   5
   6 TX synchronous with receiver: the RMR should not be changed and
   7 the RCSR.RE should be set in playback.
   8 RX synchronous with transmitter: the TMR should not be changed and
   9 the TCSR.TE should be set in recording.
