1 # SPDX-License-Identifier: GPL-2.0 2 # 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. 6 # 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 # - of-fullname-regex: regular expression to match against the OF_FULLNAME 15 # property. Useful when the controller's address is not unique across other 16 # sibling controllers. In this case, dt-mmio can't be used, and this property 17 # allows the matching to include parent nodes as well to make it unique. 18 # - usb-version: for USB controllers to differentiate between USB3 and USB2 19 # buses sharing the same controller. 20 # - acpi-uid: _UID property of the controller as supplied by the ACPI. Useful to 21 # distinguish between multiple PCI host controllers. 22 # 23 # The 'devices' key defines a list of devices that are accessible under that 24 # controller. A device might be a leaf device or another controller (see 25 # 'Dell Inc.,XPS 13 9300.yaml'). 26 # 27 # The 'path' key is needed for every child device (that is, not top-level) to 28 # define how to reach this device from the parent controller. For USB devices it 29 # follows the format \d(.\d)* and denotes the port in the hub at each level in 30 # the USB topology. For PCI devices it follows the format \d.\d(/\d.\d)* 31 # denoting the device (identified by device-function pair) at each level in the 32 # PCI topology. 33 # 34 # The 'name' key is used in the leaf devices to name the device for clarity in 35 # the test output. 36 # 37 # For USB leaf devices, the 'interfaces' key should contain a list of the 38 # interfaces in that device that should be bound to a driver. 39 # 40 - type: usb-controller 41 dt-mmio: 11200000 42 usb-version: 2 43 devices: 44 - path: 1.4.1 45 interfaces: [0, 1] 46 name: camera 47 - path: 1.4.2 48 interfaces: [0, 1] 49 name: bluetooth 50 - type: pci-controller 51 dt-mmio: 11230000 52 devices: 53 - path: 0.0/0.0 54 name: wifi
