| # This is the device definition for the Google Spherion Chromebook. |
| # The filename "google,spherion" comes from the Devicetree compatible, so this |
| # file will be automatically used when the test is run on that machine. |
| # |
| # The top-level is a list of controllers, either for USB or PCI(e). |
| # Every controller needs to have a 'type' key set to either 'usb-controller' or |
| # 'pci-controller'. |
| # Every controller needs to be uniquely identified on the platform. To achieve |
| # this, several optional keys can be used: |
| # - dt-mmio: identify the MMIO address of the controller as defined in the |
| # Devicetree. |
| # - usb-version: for USB controllers to differentiate between USB3 and USB2 |
| # buses sharing the same controller. |
| # - acpi-uid: _UID property of the controller as supplied by the ACPI. Useful to |
| # distinguish between multiple PCI host controllers. |
| # |
| # The 'devices' key defines a list of devices that are accessible under that |
| # controller. A device might be a leaf device or another controller (see |
| # 'Dell Inc.,XPS 13 9300.yaml'). |
| # |
| # The 'path' key is needed for every child device (that is, not top-level) to |
| # define how to reach this device from the parent controller. For USB devices it |
| # follows the format \d(.\d)* and denotes the port in the hub at each level in |
| # the USB topology. For PCI devices it follows the format \d.\d(/\d.\d)* |
| # denoting the device (identified by device-function pair) at each level in the |
| # PCI topology. |
| # |
| # The 'name' key is used in the leaf devices to name the device for clarity in |
| # the test output. |
| # |
| # For USB leaf devices, the 'interfaces' key should contain a list of the |
| # interfaces in that device that should be bound to a driver. |
