* 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";
