Sorry I was travelling so not realy on top of email for last few days...

Now I am not sure we can send this to -rc.
If it were just this one, we could have pushed but it also depends on a new API
which is sitting in my -next. I am not super comfortable to send that to Linus
for the -rcs. Sure, he would scream at me!

Also another point worth considering is the approach Russell suggested, I havent
gotten a chance to dig deeper but if I understood it correctly then programming
the device_dma_parameters should be the right thing to do. Again I need to look
deeper and esp wrt edma
