+OHCI
+Required properties:
+ - compatible: should be "samsung,exynos4210-ohci" for USB 2.0
+ OHCI companion controller in host mode.
+ - reg: physical base address of the controller and length of memory mapped
+ region.
+ - interrupts: interrupt number to the cpu.

+ compatible = "samsung,exynos4210-ohci";
+ reg = <0x12120000 0x100>;
+ interrupts = <0 71 0>;
