Then we'd still have a dependency of common code on OF and ACPI. On the other hand we'd get free OF and ACPI dma ranges parsing for everyone, which might be handy. And which would really help mitigating the risk that we missed some bus that gets dma configuration from OF, so maybe it actually is a good idea. I'd just rename it to dma_default_configure or similar in that case. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
