At this moment, only the DMA controller and queue manager are supported. Support for the buffer manager is lacking but these chips don't have it anyway.quoted
Signed-off-by: Sergei Shtylyov<redacted> Signed-off-by: Sekhar Nori<redacted>Russell, you have recently discarded this patch from your patch system. Can we know the reason?
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.
