Could you add more details about the omap-usb2?

You must update the Documentation binding with that compatible name.
Is it already part of the driver serie? The MUSB driver is referring to
"ti,musb-omap2430" only.

There is no ocp2scp_usb_phy in the current omap4.dtsi?
What base did you used?

You have to use lo/devel-dt branch as a base. All the latest DTS patches
an in there for 3.7.
