-* 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>;
-};
