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

| interrupts = <17 /* usbss */ |

| port0-mode = <3>; |
| port1-mode = <3>; |
| power = <250>; |
