Yet another feature is DMA cache coherency management (primarily streaming DMA) and I have a patch but I want this driven via DT rather than drivers or SoC code calling set_dma_ops explicitly (the bindings definition is work in progress).

Is there the plan or the progress about this part (streaming DMA)? :)

You can grab a patch here:

https://git.kernel.org/cgit/linux/kernel/git/cmarinas/linux-aarch64.git/comm...

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.
