There are a number of users, but most of them are bogus since they can just as easily be expressed via a compatible value. There are a few cases where they are required. PCI bus nodes, memory nodes, and cpus for example. General rule here is avoid device_type entirely unless some core infrastructure of the kernel requires it. g. -- 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
