Yes, I agree I will check if it's really needed.
I think this was explained before. Anyway, this is needed to force width to 32, no matter actual sample width. That's a requirement of HDMI codec. I believe Marcus Cooper have another codec which also needs fixed width.
There is no similar property for I2S, so TDM one is used here.
Best regards, Jernej
