Without knowing what the previous discussion was it's hard to comment,
it sounds like some prior review comments are just being ignored here
but since I'm not turning up anything with this subject line I've no
idea what that might have been (and that's very concerning in itself
given that this is apparently v7...).  I'm also concerned that there
isn't a version of this for sun6i, it's going to make all the
cut'n'pasting between the two drivers harder if we make changes in one
and not the other.

If the concern from the previous reviews to do with not using DMA is
there some reason it's hard to do DMA?
