It is device_type for PCIe right now, I'm afraid. This was what we agreed 
upon. Here a code sniplet from the patch:

	/* Check if device_type property is set to "pci" or "pci-endpoint".
	 * Resulting from this setup this PCIe port will be configured
	 * as root-complex or as endpoint.
	 */
	val = of_get_property(port->node, "device_type", NULL);
	if (!strcmp(val, "pci-endpoint")) {
		port->endpoint = 1;
	} else if (!strcmp(val, "pci")) {
		port->endpoint = 0;
	} else {
		printk(KERN_ERR "PCIE: missing or incorrect device_type for %s\n",
		       np->full_name);
		return;
	}
