It’s informational, but not only for debugging.

For instance the beaglebone capemanager could put there the compatible and the resource declaration properties. But that’s going to come later. > Rob > — Regards — Pantelis -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
