+Generic Bluetooth controller over USB (btusb driver)
+---------------------------------------------------
+
+Required properties:
+
+ - compatible : should comply with the format "usbVID,PID" specified in
+ Documentation/devicetree/bindings/usb/usb-device.txt
+ At the time of writing, the only OF supported devices
+ (more may be added later) are:
+
+ "usb1286,204e" (Marvell 8997)
+
+Also, vendors that use btusb may have device additional properties, e.g:
+Documentation/devicetree/bindings/net/marvell-bt-8xxx.txt
+
+Optional properties:
+
+ - interrupt-parent: phandle of the parent interrupt controller
+ - interrupt-names: (see below)
+ - interrupts : The interrupt specified by the name "wakeup" is the interrupt
+ that shall be used for out-of-band wake-on-bt. Driver will
+ request this interrupt for wakeup. During system suspend, the
+ irq will be enabled so that the bluetooth chip can wakeup host
+ platform out of band. During system resume, the irq will be
+ disabled to make sure unnecessary interrupt is not received.
+
+Example:
+
+Following example uses irq pin number 3 of gpio0 for out of band wake-on-bt:
+
+&usb_host1_ehci {
+ status = "okay";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ mvl_bt1: bt@1 {
+ compatible = "usb1286,204e";
+ reg = <1>;
+ interrupt-parent = <&gpio0>;
+ interrupt-name = "wakeup";
+ interrupts = <3 IRQ_TYPE_LEVEL_LOW>;
+ };
+};
