I second the first proposal. The TCON structure has not changed since the A10. Allwinner just removed the unused channels. Channel 1 is removed from the first TCON, and channel 0 is removed from the second TCON. So Allwinner is more or less committing to a static mapping for the display pipeline outputs.
