+OMAP GLUE AND OTHER OMAP SPECIFIC COMPONENTS
+
+OMAP MUSB GLUE
+ - compatible : Should be "ti,omap4-musb" or "ti,omap3-musb"
+ - ti,hwmods : must be "usb_otg_hs"
+ - ti,has-mailbox : to specify that omap uses an external mailbox
+   (in control module) to communicate with the musb core during device connect
+   and disconnect.
+ - 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.
+
+Optional properties:
+ - ctrl-module : phandle of the control module this glue uses to write to
+   mailbox
+
+SOC specific device node entry

+
+OMAP CONTROL USB
+
+Required properties:
+ - compatible: Should be "ti,omap-control-usb"
+ - reg : Address and length of the register set for the device. It contains
+   the address of "control_dev_conf" and "otghs_control" or "phy_power_usb"
+   depending upon omap4 or omap5.
+ - reg-names: The names of the register addresses corresponding to the registers
+   filled in "reg".
+ - ti,type: This is used to differentiate whether the control module has
+   usb mailbox or usb3 phy power. omap4 has usb mailbox in control module to
+   notify events to the musb core and omap5 has usb3 phy power register to
+   power on usb3 phy. Should be "1" if it has mailbox and "2" if it has usb3
+   phy power.
