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.
+
+Required properties:
+- compatible: must be "maxim,ds2760-w1"

+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.

+Example:
+
+ onewire {

+ gpios = <&gpio 0 GPIO_ACTIVE_HIGH>;

+ w1_slave: slave@0 {
