21
22	When compatible with the generic version, nodes must list the
23	SoC-specific version corresponding to the platform first followed
24	by the generic version.
25
26  - reg: Base address and length of the register for the USBHS
27  - interrupts: Interrupt specifier for the USBHS
28  - clocks: A list of phandle + clock specifier pairs
29
30Optional properties:
31  - renesas,buswait: Integer to use BUSWAIT register
32  - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
33			 function should be enabled
34  - phys: phandle + phy specifier pair
35  - phy-names: must be "usb"
36  - dmas: Must contain a list of references to DMA specifiers.
37  - dma-names : named "ch%d", where %d is the channel number ranging from zero
38                to the number of channels (DnFIFOs) minus one.
