[v4,2/3] kselftest: devices: Add sample board file for google,spherion
Commit Message
Add a sample board file describing the file's format and with the list
of devices expected to be probed on the google,spherion machine as an
example.
Test output:
TAP version 13
Using board file: boards/google,spherion.yaml

+# 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.
