+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.
+- maxim,pmod-enabled:  This boolean property enables the DS2760 to enter
+                       sleep mode when the DQ line goes low for greater
+                       than 2 seconds and leave sleep Mode when the DQ
+                       line goes high.
+- maxim,cache-time-ms: Time im milliseconds to cache the data for. When
+                       this time expires, the values are read again from
+                       the hardware. Defaults to 1000.
+- rated-capacity-microamp-hours:
+                       The rated capacity of the battery, in mAh.
+                       If not specified, the value stored in the
+                       non-volatile chip memory is used.
