Sorry, I simply wasn't aware that this is what I'm being asked for. Is the device a MFD? - Yes it is. In this case the child node would be a 'ti,syscon-reset' which doesn't have YAML bindings. Should I include it as object without $ref or do I need to convert ti,syscon-reset.txt to yaml first, and then reference it as child node in the MFD?
