You can grab a patch here:
https://git.kernel.org/cgit/linux/kernel/git/cmarinas/linux-aarch64.git/commit/?h=devel&id=96f083d416c0d01687ed5b37074831f461838455
However, I'd like to see some progress on defining the system topology
via DT rather than driver manually setting the dma ops. Dave Martin is
looking at this but I don't have an ETA yet.
