+Samsung S3C2410 and compatible SoC USB controller
+
+OHCI
+
+Required properties:
+ - compatible: should be "samsung,s3c2410-ohci" for USB host controller
+ - reg: address and lenght of the controller memory mapped region
+ - interrupts: interrupt number for the USB OHCI controller
+ - clocks: Should reference the bus and host clocks
+ - clock-names: Should contain two strings
+ "usb-bus-host" for the USB bus clock
+ "usb-host" for the USB host clock
+
+Example:
+
+usb0: ohci@49000000 {
+ compatible = "samsung,s3c2410-ohci";
+ reg = <0x49000000 0x100>;
+ interrupts = <0 0 26 3>;
+ clocks = <&clocks UCLK>, <&clocks HCLK_USBH>;
+ clock-names = "usb-bus-host", "usb-host";
+};
