+* 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";

+
+Required properties:
+
+ - compatible: "w1-gpio"
+ - gpios: one or two GPIO specs:
+		- the first one is used as data I/O pin
+		- the second one is optional. If specified, it is used as
+		  enable pin for an external pin pullup.
+
+Optional properties:
+
+ - linux,open-drain: if specified, the data pin is considered in
+		     open-drain mode.
+
+Examples:
+
+	onewire@0 {
+		compatible = "w1-gpio";
+		gpios = <&gpio 126 0>, <&gpio 105 0>;
+	};
