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 55
