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