The recently merged DT kselftest [3] detects probe issues for all devices described statically in the DT. That leaves out devices discovered at run-time from discoverable buses. This is where this test comes in. All of the devices that are connected through discoverable buses (ie USB and PCI), and which are internal and therefore always present, can be described based on their position in the system topology in a per-platform YAML file so they can be checked for. The test will check that the device has been instantiated and bound to a driver. Patch 1 introduces the test. Patch 2 and 3 add the device definitions for the google,spherion machine (Acer Chromebook 514) and XPS 13 as examples.
