Do you have the related dts patches picked from next?
fdd192037fce ("ARM: dts: omap4-droid4: Fix USB PHY port naming")
e5b9fd7bdeb5 ("ARM: dts: omap4-droid4: Configure MDM6600 USB PHY")
But yeah all you need to do is have phy-mapphone-mdm6600 and
ohci-platform loaded and then ifconfig should show four wwan
interfaces being added.

Tony
