1# SPDX-License-Identifier: GPL-2.02#3# This is the device definition for the Google Spherion Chromebook.4# The filename "google,spherion" comes from the Devicetree compatible, so this5# 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' or9# 'pci-controller'.10# Every controller needs to be uniquely identified on the platform. To achieve11# this, several optional keys can be used:12# - dt-mmio: identify the MMIO address of the controller as defined in the13# Devicetree.14# - of-fullname-regex: regular expression to match against the OF_FULLNAME15# property. Useful when the controller's address is not unique across other16# sibling controllers. In this case, dt-mmio can't be used, and this property17# allows the matching to include parent nodes as well to make it unique.18# - usb-version: for USB controllers to differentiate between USB3 and USB219# buses sharing the same controller.20# - acpi-uid: _UID property of the controller as supplied by the ACPI. Useful to21# distinguish between multiple PCI host controllers.22#23# The 'devices' key defines a list of devices that are accessible under that24# controller. A device might be a leaf device or another controller (see25# 'Dell Inc.,XPS 13 9300.yaml').26#27# The 'path' key is needed for every child device (that is, not top-level) to28# define how to reach this device from the parent controller. For USB devices it29# follows the format \d(.\d)* and denotes the port in the hub at each level in30# 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 the32# PCI topology.33#34# The 'name' key is used in the leaf devices to name the device for clarity in35# the test output.36#37# For USB leaf devices, the 'interfaces' key should contain a list of the38# interfaces in that device that should be bound to a driver.39#40- type: usb-controller41 dt-mmio: 1120000042 usb-version: 243 devices:44 - path: 1.4.145 interfaces: [0, 1]46 name: camera47 - path: 1.4.248 interfaces: [0, 1]49 name: bluetooth50- type: pci-controller51 dt-mmio: 1123000052 devices:53 - path: 0.0/0.054 name: wifi55
