This patch add a generic w1 bindings document that merely describes how
slave deviceses are grouped under master nodes. It also adds a specific
binding for the ds2760 battery monitor.

+Devicetree bindings for Maxim DS2760
+====================================
+
+The ds2760 is a w1 slave device and must hence have its sub-node in DT
+under a w1 bus master node.
+
+The device exposes a power supply, so the details described in
+Documentation/devicetree/bindings/power/supply/power_supply.txt apply.
+
+Required properties:
+- compatible: must be "maxim,ds2760"
+
+Optional properties:
+- power-supplies:      Refers to one or more power supplies connected to
+                       this battery.

+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, one
+one slave is allowed per bus master.
+
+
+Example:
+
+       onewire {
+               compatible = "w1-gpio";
+               gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;

+               battery {
+                       compatible = "maxim,ds2760";
