This is awesome! Glad to see you have the superspeed phy working. I'm a 
bit confused though since the of_fixup code in mach-snapdragon 
configures all the usb controllers for high speed only and removes the 
reference to the superspeed phy, is there some missing commit to adjust 
this?

Kind regards,
