| 3 | OMAP MUSB GLUE |
| 4 | - compatible : Should be "ti,omap4-musb" or "ti,omap3-musb" |
| 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 | - interface_type : This is a board specific setting to describe the type of |
| 12 | interface between the controller and the phy. It should be "0" or "1" |
| 13 | specifying ULPI and UTMI respectively. |
| 14 | - mode : Should be "3" to represent OTG. "1" signifies HOST and "2" |
| 15 | represents PERIPHERAL. |
| 16 | - power : Should be "50". This signifies the controller can supply upto |
| 17 | 100mA when operating in host mode. |
