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