Oh, dear - this means we don't actually have a generic API at all. Is there any effort being made to make this generally available?
Yes there is, and in fact in next/master there is generic dma_mmap_writecombine. I'm not quite sure how it behaves on non ARM archs though. But in theory it should fallback to a normal coherent mapping. Marek did a lot of work on this, I've put him on Cc.
OK, that's not so bad. Where is this code, can we merge it into ALSA? If not it's probably best to punt until after the merge window.
