dt-bindings: w1: document generic onewire bindings 



This patch adds a generic w1 bindings document that describes how w1
slave deviceses are grouped under master nodes. It also augments the
existing w1-gpio.txt document a bit.

Generic devicetree bindings for onewire (w1) busses

===================================================



Onewire busses are described through nodes of their master bus controller.

Slave devices are listed as sub-nodes of such master devices. For now, only

one slave is allowed per bus master.





Example:



	charger: charger {

		compatible = "gpio-charger";

		charger-type = "mains";

		gpios = <&gpio 1 GPIO_ACTIVE_LOW>;

	};



	onewire {

		compatible = "w1-gpio";

		gpios = <&gpio 100 0>, <&gpio 101 0>;



		battery {

			compatible = "maxim,ds2760";

			power-supplies = <&charger>;

		};

	};
