10- reg: should contain one register range i.e. start and length
11- interrupts: description of the interrupt line
12
13Optional properties:
14- clocks: should contain the IP block clock
15- clock-names: should be "PCLK" for the IP block clock
16
17Required properties for "cortina,gemini-usb" compatible:
