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

If you dont have any comments, can you take this for 3.12?

That's not a very good name for a phy? It looks like a usb module.
The bindings specify only ti,omap-usb2 or ti,omap-usb3 for USB2 or USB3.
I guess it should be one of them and potentially the binding should be
updated with ti,omap-usb2-phy and ti,omap-usb3-phy names while we can
still do it.

Why do you need a different node name here? It should be a generic name
to identify the function, so usbphy or usb-phy seems good enough.

What is the purpose of the phy-names? Is it relevant to add the SoC name
in something that usually, at least for the clocks and IRQs, is IP specific?
The current documentation does not explain it and does not support phys
property either.
synopsys DWC3 CORE
DWC3- USB3 CONTROLLER
Required properties:
- compatible: must be "synopsys,dwc3"
- reg : Address and length of the register set for the device
- interrupts: Interrupts used by the dwc3 controller.
- usb-phy : array of phandle for the PHY device
Is there some binding update ongoing for 3.12?
