1Generic Bluetooth controller over USB (btusb driver) 2--------------------------------------------------- 3 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-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. 26 27Example: 28 29Following 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}; 44
