I have one top level driver node and multiple instance of subnodes - 4 MC, 4 L2/L1, 1 L3C, and 1 SoC EDAC for now. The L3C many be multiple instance in the future. Just a note, the way EDAC looks up instance is by pointer of struct device. It doesn't need anything more than that. -Loc -- 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
