Florent's work *was* on mainline.
and then they took it off because it was unmantained? You've spoken about Thomas(in CC) not ready, maybe I could help on that if it's public to accelerate. If I'm able to of course, this is my primary concern.
Otherwise, in which way can I help improving it to make it accept to linux-sunxi? Starting from Florent's work and porting it to sunxi-next to begin? And after that adding all features you've listed? Tell me what I can do(I repeat, if I'm able to).
