What is the proper way to know this information?
Or how do I tell that each DAI is unidirectional?
If it's not got any playback or capture capabilities.
On mx28evk there are two DAIs connected to a single sgtl5000:
- One corresponds to the serial audio interface 0 (SAIF0) and it is playback only
- The other corresponds to the serial audio interface 1 (SAIF1) and it is capture only.
Should I create and pass device tree bindings like "playback-only" and "capture-only", so that we can avoid having both playback and capture capabilities for SAIF0 and SAIF1?
Or is there already a mechanism in place that I can use to configure a DAI as unidirectional?
Thanks,
