Isn't that possible? I saw that of_node_get|put is used in .probe > on few places in drivers. So far we aren't selecting that config on ARM. If you look at of_device_alloc() you'll see dev->dev.of_node = of_node_get(np); so any platform devices created from of_platform_populate won't have their of_node go away. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation -- 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
