In the datasheet I see the I2S_SPDIF_MAP_INV control, but it looks like this pairwise inverts all I2S pairs. Is there a control to invert only one pair(such as pair 2, ch 3/4) only?
The actual pinout is determined by I2S_SPDIF_MAP_ROT[1:0]. What pinout are you needing?
Looks like I won't be needing to do this anymore, but the pinout I was looking for was:
AP2: I2S1, L & R inverted
