This sounds interesting. We are currently finding the omap serial driver awefully slow at handling serial traffic with ti's 3.12.y kernel branch, while the 3.8.y was seemingly a bit better (on the dra7xx eval board). Haven't had time to really investigate that yet though.

I would certainly love to see ttyS instead of ttyO. But of course I am working on a new system that isn't released yet so changing things is a complete non issue for me. :)
I should give this driver a try and see how it compares so far.
