Have you read that document I posted link to?


It was decided by
Linaro that CSRT will not be supported for ARM64.

Interesting, ARM64 platforms are not going to have more than one DMAC
per system?

I cannot imagine that being true, and I don't see why Linaro would
decide such a thing.

See this.

It does appear that it's not relevant to this device and driver, given
the lack of clients, unless I've misunderstood?

Yeah, just a side note.
