Hi, This series adds support for OF and ACPI device graph parsing to the device connection API. Handling the graph is straightforward, but because I'm adding that fwnode member to struct device_connection, I had to make sure all the existing users consider it. The plan is to only support matching with fwnode in the future, so no more device name matching. The software fwnodes that we now have in kernel should make that possible, once we add support for references to them.
