is it only inventra dma that suffers from this ? If not, we could move
this check before even calling the dma routine.
Yes, it's only the integrated Inventra DMA that behaves like this.
Anyway, I don't think newer versions of the IP are being used by
anyone without the Inventra DMA. The older versions though are
sometimes used with external DMA controllers.
DA8xx/OMAP-L1x has MUSB version 1.800 and external, CPPI 4.1 DMA
controller.
