DT is based on the actual HW construction, not how a particular OS wants to expose that HW through its APIs. If there is a single HW block, there should be a single DT node, even if that HW block supports multiple channels. In some circumstances, it might make sense for the single top-level node that represents the HW-block to have child nodes that represent the channels, depending on what exactly the HW is doing and whether this level of detail is useful in DT. I would qualify this as rare though. -- 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
