Hi,
Before I look any further into this, could you please explain why this is made to be entirely separate from what we have in drivers/tty/serial/8250/8250_aspeed_vuart.c ?
I quickly went through some functions and they've significant parts in common with no variations at all in many functions and you're defines are 1:1 too (except for the DMA buf sizes). It would seem much better to add the missing functionality into 8250_aspeed_vuart.c rather than creating something from scratch with large overlap with existing code.
If you intend to keep it as a separate one, you should have a rather good justification for it.
