+ Roger Hi George, Yes, I had some comment about the "ti'type" in Roger's series that will be applicable here as well.

There are 2 instances of usb controllers and these instances for those 2 phys, which essentially dont have any reg property.

The phy part, especially was added with the generic phy framework in mind. The generic phy framework uses phys and phy-names instead of usb-phy.

Is there any already bindings that defined phys and phy-names in the kernel? I couldn't find them in 3.11-rc5. And anyway the current bindings for dwc3 is not aligned with what you are doing here. So you have to change the binding before using it in this DTS.
