There are already nodes with 'usb' name:
	ehci: usb@...10000 {
		compatible = "samsung,exynos4210-ehci";
		...
	}
	ohci: usb@...20000 {
		compatible = "samsung,exynos4210-ohci";
	}
Having nodes with the same name but some with address some not, should
work (none should be overridden)... but looks a little bit weird.

Anyway I am fine with both.

Thanks for review and comments. I already spotted the 'memory' node
issue so I won't be replying to you with acknowledging comments. :)

BR,
