1AM33XX 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.
