Just remember that we're moving stuff to DMA engine, and that means the sDMA device has DMA masks, but none of the peripherals which make use of sDMA should have DMA masks set. The reason for this is because the device responsible for accessing memory is sDMA, not the peripheral device, and therefore any memory properties for DMA should come from the sDMA device, not the peripheral device. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
