Dove Audio 0:
- I2S in
- I2S out
- No SPDIF

Dove Audio 1:
- I2S in
- I2S out
- SPDIF out only

Both these variants occur on the same SoC.

Kirkwood:
- I2S in
- SPDIF in
- I2S out
- SPDIF out

Preconditions:
1. Only one input can be used at any one time.
2. One output can be used or both if enabled simultaneously.
