Subject: [PATCH] ASoC: fsl_sai: handle slave mode per TX/RX direction
|
||
|
|
|
||
|
|
The SAI interface can be a clock supplier or consummer
|
||
|
|
as function of stream direction, ie when interacting
|
||
|
|
with I2S XTOR. Removed FSL_SAI_RFR define as it is now
|
||
|
|
referred as FSL_SAI_RFR0.
|
