Required properties:
 - compatible : Should be "stericsson,db8500-musb"
 - reg        : Offset and length of registers
 - interrupts : Interrupt; mode, number and trigger
 - dr_mode    : Dual-role; either host mode "host", peripheral mode "peripheral"
                or both "otg"

Optional properties:
 - dmas       : A list of dma channels;
                dma-controller, event-line, fixed-channel, flags
 - dma-names  : An ordered list of channel names affiliated to the above

Example:

	compatible = "stericsson,db8500-musb";
	reg = <0xa03e0000 0x10000>;
	interrupts = <0 23 0x4>;
	interrupt-names = "mc";

	dr_mode = "otg";
