Subject: [PATCH] ASoC: fsl-sai: set xCR4/xCR5/xMR for SAI master mode
|
|
|
|
For SAI master mode, when Tx(Rx) sync with Rx(Tx) clock, Rx(Tx) will
|
|
generate bclk and frame clock for Tx(Rx), we should set RCR4(TCR4),
|
|
RCR5(TCR5) and RMR(TMR) for playback(capture), or there will be sync
|
|
error sometimes.
