+ - ti,hwmods : must be "am35x_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"
+ - interface-type : Should be set to "1". (The AM35xx SOCs feature an

+ - mode : Should be "3" to represent OTG. "1" signifies HOST and "2"
+ represents PERIPHERAL.
+ - power : Should be "50". This signifies the controller can supply up to
