This patch creates unique DMA channels for the second USB
interface, otherwise the second USB interface is not usable
at all.
MUSB_DMA_NUM_CHANNELS is 15, so if you pass any dma-names > 15 (>
rx15/tx15),
the dma_controller_create in musb_core.c fails and it falls back to PIO
mode.
What's the proper fix for the DMA issue?
I could not understand what issue you are referring to.
In my setup I use both BBB and BBW (Beagle Bone Black/White)with one USB
in host (USB1)
and one USB in gadget (USB0). I dont see any issues with DMA.
Can you be more specific?
