This is the result of a combined effort by Chip Coldwell, Remy Bohmer and me. The patches should apply cleanly onto Linus' latest git tree. It all seems to behave both with and without DMA enabled, but I'll do some more testing tomorrow. Note that break and error handling doesn't work too well with DMA enabled. This is a common problem with all the efforts I've seen adding DMA support to this driver (including my own). I'm tempted to just ignore the problem for now and hopefully come up with a solution later. Everyone, please give it a try and/or review the code. PS: Andrew, I'm sending it to you because I believe you're the maintainer of this driver, although MAINTAINERS doesn't say anything about it. Please let me know if this isn't how you want it.
