dtc should complain here - you need:
	dwc3@15400000
In the same time I think the address node does not have to be put after
parent's usb.

No, it didn't complain. Anyway, I will update as it's already taken care
in other Exynos SoC DTSi files.

It only complains if you run dtc with warnings enabled, i.e: make W=1
exynos7-espresso.dtb
