1	AM33XX MUSB GLUE
2	 - compatible : Should be "ti,musb-am33xx"
3	 - reg : offset and length of register sets, first usbss, then for musb instances
4	 - interrupts : usbss, musb instance interrupts in order
5	 - ti,hwmods : must be "usb_otg_hs"
6	 - multipoint : Should be "1" indicating the musb controller supports
7	   multipoint. This is a MUSB configuration-specific setting.
8	 - num-eps : Specifies the number of endpoints. This is also a
9	   MUSB configuration-specific setting. Should be set to "16"
10	 - ram-bits : Specifies the ram address size. Should be set to "12"
11	 - port0-mode : Should be "3" to represent OTG. "1" signifies HOST and "2"
12	   represents PERIPHERAL.
13	 - port1-mode : Should be "1" to represent HOST. "3" signifies OTG and "2"
14	   represents PERIPHERAL.
15	 - power : Should be "250". This signifies the controller can supply upto
16	   500mA when operating in host mode.
