just add your ds2482 as child node to the i2c controller like this:


	I2C0: i2c@860 {
		compatible = "fsl,mpc823-i2c",
			     "fsl,cpm1-i2c";
		reg = <0x860 0x20 0x3c80 0x30>;
		interrupts = <16>;
		interrupt-parent = <&CPM_PIC>;
		fsl,cpm-command = <0x10>;
		bus-frequency = <100000>;

		w1@aa {
			reg = <0xaa>;
			compatible = "dallas,ds2482";
		};
	};


Of course you'll have to replace "aa" with the real i2c address of the device.

Thanks,
Jochen
