Nack.
#1. Same comment as before on spdifout B and SPDIF HDMI input.
#2. the u200 is a special reference device with 2 onboards codecs,
external connector for audio daugther boards and internal codec.
I don't see another board using that configuration, which would make
them incompatible
#3. TDM B is a bad choice on this board as it connected to one of the
i2s codecs of the board, which won't take 4 lines ine.
