Most platforms define the interrupt parent somewhere in the top-level node and have it inherited for child devices instead of having to repeat it for each device. But I guess it's also okay to make it explicit. [...]

+ interrupt-parent;I /think/ in this case you can leave this out. At least there doesn't seem to be any other such usage in the tree. Thierry
