So since the use of dma_request_slave_channel() is not upstream, I guess this will break DMA use (i.e slow down transfers!) on all device tree boots?
I'd be happy to apply it once the MMCI patch is in linux-next indicating there may just be a window in the merge period where it falls back to IRQ mode, but I don't want to disable DMA on DT boots for an entire kernel cycle just like that.
Not applied as of yet.
Yours, Linus Walleij
