3# This is the device definition for the Google Spherion Chromebook.
4# The filename "google,spherion" comes from the Devicetree compatible, so this
5# file will be automatically used when the test is run on that machine.

7# The top-level is a list of controllers, either for USB or PCI(e).
8# Every controller needs to have a 'type' key set to either 'usb-controller' or
9# 'pci-controller'.
10# Every controller needs to be uniquely identified on the platform. To achieve
11# this, several optional keys can be used:
12# - dt-mmio: identify the MMIO address of the controller as defined in the
13# Devicetree.
14# - usb-version: for USB controllers to differentiate between USB3 and USB2
15# buses sharing the same controller.
16# - acpi-uid: _UID property of the controller as supplied by the ACPI. Useful to
17# distinguish between multiple PCI host controllers.
18#
19# The 'devices' key defines a list of devices that are accessible under that
20# controller. A device might be a leaf device or another controller (see
21# 'Dell Inc.,XPS 13 9300.yaml').
22#
23# The 'path' key is needed for every child device (that is, not top-level) to
24# define how to reach this device from the parent controller. For USB devices it
25# follows the format \d(.\d)* and denotes the port in the hub at each level in
26# the USB topology. For PCI devices it follows the format \d.\d(/\d.\d)*
27# denoting the device (identified by device-function pair) at each level in the
28# PCI topology.
29#
30# The 'name' key is used in the leaf devices to name the device for clarity in
31# the test output.
32#
33# For USB leaf devices, the 'interfaces' key should contain a list of the
34# interfaces in that device that should be bound to a driver.
