Subject: [PATCH 0/3] ASoC: imx-audmix: Split capture device to be a new device

The transmitter and receiver part of the SAI interface need to be
configured with different master/slave mode, especially to work
with the audiomix module.

The SAI1 TX is in master mode, but SAI1 RX is in slave mode.
So add another two DAIs for TX and RX separately in fsl_sai driver.

There will be three devices for audiomix sound card, hw:x,0 is
the playback device for one SAI, hw:x,1 is the playback device
for another SAI, hw:x,2 is the capture device for audmix
output.

Shengjiu Wang (3):
  ASoC: fsl_sai: Add separate DAI for transmitter and receiver
  ASoC: fsl_audmix: Split playback and capture stream to different DAI
  ASoC: imx-audmix: Split capture device for audmix
