It was recently discussed with TI, and various people raised concerns
about it. I don't remember the exact details, and I wish they'd raise
them with the patch author directly. It may have been that it's
inventing its own API rather than using something like the DMA engine
API.
Adding linux-omap to try to get a response there.
