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:
