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.

   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.

Sergei,
This issue was discussed recently at TI and proposal was to place it to
drivers/dma folder. Moreover, even Felipe also seems to move other musb
DMAs (Inventra, CPPI3.0, TUSB) to drivers/dma.

Regards,
Ajay
