Just pass it the page and offset rather than the address.
Wait a minute ... dma_map_single() should still work, it will just call dma_map_page() underneath. All dma_ops should have a ->map page callback. Do you have any dma_ops set for your device at all ? I wonder how we set the dma_ops for platform devices nowadays ... We use to have this fallback to direct ops when the dma_ops are NULL but that is gone and I see no suitable replacement to set them on platform devices for embedded archs ... oops... Kumar, Becky, what's the situation there ?
