# SPDX-License-Identifier: GPL-2.0 # # 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. # - type: usb-controller dt-mmio: 11200000 usb-version: 2 devices: - path: 1.4.1 interfaces: [0, 1] name: camera - path: 1.4.2 interfaces: [0, 1] name: bluetooth - type: pci-controller dt-mmio: 11230000 devices: - path: 0.0/0.0 name: wifi
