I am only saying that this "hot-plug a device at a non hot-plugagle bus at runtime" is not limited to DT but this solution is. X86 + ACPI is not the only limitation. ARM is (forced) going to ACPI as well as far I know. And this solution is limited to DT. This is what I am pointing out. > His use case is not uncommon, believe it or not, and x86 would benefit from > something this flexible. I *think* a more flexible solution would be something like bus_type which is exposed via configfs. It would be attached behind a certain device/bus where the "physical" hotplug interface is. The user would then be able to read the configuration based on whatever information he has and could then create devices he likes at runtime. This wouldn't depend much on the firmware that is used but would require a little more work I think. > Regards > > -- Pantelis Sebastian -- 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
