Im aware of that but the OHCI core doesnt do that, it uses the DMA API, which is entirely reasonable, given its tring to access a DMA-able chunk of memory.
I *could* write a new driver ohci-ioremapped for all these chips but its needless duplication which is going to result in bugs bveing fixed in one ohci driver and not the other.
why not simply expand the DMA API to allow DMA to these easily DMA-able chips ? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
