NAK -- interpretation of the MODE parameter is correct
(though it's not clear to me that the callers set it right),
but this won't apply to current GIT since the code differs.
I don't know what this is *against* but it's not mainline
or the OMAP tree...
csr |= (musb_channel->epnum << MUSB_HSDMA_ENDPOINT_SHIFT)
| (1 << MUSB_HSDMA_ENABLE_SHIFT)
| (1 << MUSB_HSDMA_IRQENABLE_SHIFT)
| (musb_channel->transmit
? (1 << MUSB_HSDMA_TRANSMIT_SHIFT)
: 0);
Ajay, if this needs to merge to mainline (e.g. so it can be
pulled down to omap-git and fix DMA there) please re-issue.
