1 Generic Bluetooth controller over USB (btusb driver)
2 ---------------------------------------------------
3
4 Required 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
13 Also, vendors that use btusb may have device additional properties, e.g:
14 Documentation/devicetree/bindings/net/marvell-bt-8xxx.txt
15
16 Optional properties:
17
18   - interrupt-parent: phandle of the parent interrupt controller
19   - interrupt-names: (see below)
20   - interrupts : The interrupt specified by the name "wakeup" is the interrupt
21                  that shall be used for out-of-band wake-on-bt. Driver will
22                  request this interrupt for wakeup. During system suspend, the
23                  irq will be enabled so that the bluetooth chip can wakeup host
24                  platform out of band. During system resume, the irq will be
25                  disabled to make sure unnecessary interrupt is not received.

27 Example:
28
29 Following example uses irq pin number 3 of gpio0 for out of band wake-on-bt:
30
31 &usb_host1_ehci {
32     status = "okay";
33     #address-cells = <1>;
34     #size-cells = <0>;
35
36     mvl_bt1: bt@1 {
37         compatible = "usb1286,204e";
38         reg = <1>;
39         interrupt-parent = <&gpio0>;
40         interrupt-name = "wakeup";
41         interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
42     };
43 };
