1Generic Bluetooth controller over USB (btusb driver)
2---------------------------------------------------

4Required properties:
5
6  - compatible : should comply with the format "usbVID,PID" specified in
7		 Documentation/devicetree/bindings/usb/usb-device.txt
8		 At the time of writing, the only OF supported devices
9		 (more may be added later) are:
10
11		  "usb1286,204e" (Marvell 8997)
12
13Also, vendors that use btusb may have device additional properties, e.g:
14Documentation/devicetree/bindings/net/marvell-bt-8xxx.txt
15
16Optional properties:
17
18  - interrupt-names: (see below)
19  - interrupts : The interrupt specified by the name "wakeup" is the interrupt
20		 that shall be used for out-of-band wake-on-bt. Driver will
21		 request this interrupt for wakeup. During system suspend, the
22		 irq will be enabled so that the bluetooth chip can wakeup host
23		 platform out of band. During system resume, the irq will be
24		 disabled to make sure unnecessary interrupt is not received.

26Example:
27
28Following example uses irq pin number 3 of gpio0 for out of band wake-on-bt:
29
30&usb_host1_ehci {
31    #address-cells = <1>;
32    #size-cells = <0>;
33
34    mvl_bt1: bt@1 {
35	compatible = "usb1286,204e";
36	reg = <1>;
37	interrupt-parent = <&gpio0>;
38	interrupt-name = "wakeup";
39	interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
40    };
41};
