* Freescale i.MX One wire bus master controller



Required properties:

- compatible : should be "fsl,imx21-owire"

- reg : Address and length of the register set for the device



Optional properties:

- clocks : phandle of clock that supplies the module (required if platform

		clock bindings use device tree)



Example:



- From imx53.dtsi:

owire: owire@63fa4000 {

	compatible = "fsl,imx53-owire", "fsl,imx21-owire";

	reg = <0x63fa4000 0x4000>;

	clocks = <&clks 159>;

	status = "disabled";

};
