-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.
