-Generic USB Device Properties
-
-Usually, we only use device tree for hard wired USB device.
-The reference binding doc is from:
-http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
-
-Four types of device-tree nodes are defined: "host-controller nodes"
-representing USB host controllers, "device nodes" representing USB devices,
-"interface nodes" representing USB interfaces and "combined nodes"
-representing simple USB devices.
-
-A combined node shall be used instead of a device node and an interface node
-for devices of class 0 or 9 (hub) with a single configuration and a single
-interface.
-
-A "hub node" is a combined node or an interface node that represents a USB
-hub.
-
-
-Required properties for device nodes:
-- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
-  The textual representation of VID and PID shall be in lower case hexadecimal
-  with leading zeroes suppressed. The other compatible strings from the above
-  standard binding could also be used, but a device adhering to this binding
-  may leave out all except for "usbVID,PID".
-- reg: the number of the USB hub port or the USB host-controller port to which
-  this device is attached. The range is 1-255.
-
-
-Required properties for device nodes with interface nodes:
-- #address-cells: shall be 2
-- #size-cells: shall be 0
-
-
-Required properties for interface nodes:
-- compatible: "usbifVID,PID.configCN.IN", where VID is the vendor id, PID is
-  the product id, CN is the configuration value and IN is the interface
-  number. The textual representation of VID, PID, CN and IN shall be in lower
-  case hexadecimal with leading zeroes suppressed. The other compatible
-  strings from the above standard binding could also be used, but a device
-  adhering to this binding may leave out all except for
-  "usbifVID,PID.configCN.IN".
-- reg: the interface number and configuration value
-
-The configuration component is not included in the textual representation of
-an interface-node unit address for configuration 1.
-
-
-Required properties for combined nodes:
-- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
-  The textual representation of VID and PID shall be in lower case hexadecimal
-  with leading zeroes suppressed. The other compatible strings from the above
-  standard binding could also be used, but a device adhering to this binding
-  may leave out all except for "usbVID,PID".

+title: The device tree bindings for the Generic USB Device

+
+description: |
+  Usually, we only use device tree for hard wired USB device.
+  The reference binding doc is from:
+  http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
+
+  Four types of device-tree nodes are defined: "host-controller nodes"
+  representing USB host controllers, "device nodes" representing USB devices,
+  "interface nodes" representing USB interfaces and "combined nodes"
+  representing simple USB devices.
+
+  A combined node shall be used instead of a device node and an interface node
+  for devices of class 0 or 9 (hub) with a single configuration and a single
+  interface.
+
+  A "hub node" is a combined node or an interface node that represents a USB
+  hub.
+
+properties:
+  $nodename:
+    description: Usually includes "hub" or the standard node name for
+      USB class of device, for example, "ethernet" for the USB ethernet
+      adapter, "bt" for btusb, "camera" for the USB image sensor etc.
+    pattern: "^[a-f]+@[0-9a-f]+$"
+
+  compatible:
+    description: Device nodes or combined nodes.
+      "usbVID,PID", where VID is the vendor id and PID the product id.
+      The textual representation of VID and PID shall be in lower case
+      hexadecimal with leading zeroes suppressed. The other compatible
+      strings from the above standard binding could also be used,
+      but a device adhering to this binding may leave out all except
+      for "usbVID,PID".
+    items:
+      - pattern: "^usb[0-9a-f]+,[0-9a-f]+$"
+
+  reg:
+    description: the number of the USB hub port or the USB host-controller
+      port to which this device is attached. The range is 1-255.
+    maxItems: 1
+
+  "#address-cells":
+    description: should be 1 for hub nodes with device nodes,
+      should be 2 for device nodes with interface nodes.
+    enum: [1, 2]
+
+  "#size-cells":
+    const: 0
+
+patternProperties:
+  "^interface@[0-9]+(,[0-9]+)$":
+    type: object
+    description: USB interface nodes.
+      The configuration component is not included in the textual
+      representation of an interface-node unit address for configuration 1.
+
+    properties:
+      compatible:
+        description: |
+          "usbifVID,PID.configCN.IN", where VID is the vendor id, PID is
+          the product id, CN is the configuration value and IN is the interface
+          number. The textual representation of VID, PID, CN and IN shall be
+          in lower case hexadecimal with leading zeroes suppressed.
+          The other compatible strings from the above standard binding could
+          also be used, but a device adhering to this binding may leave out
+          all except for "usbifVID,PID.configCN.IN".
+        items:
+          - pattern: "^usbif[0-9a-f]+,[0-9a-f]+.config[0-9a-f]+.[0-9a-f]+$"
+
+      reg:
+        description: should be 2 cells long, the first cell represents
+          the interface number and the second cell represents the
+          configuration value.
