+cw2015_battery
+~~~~~~~~~~~~~~~~
+
+The cellwise CW2015 is a shuntless single/multi-cell battery fuel gauge.
+
+Required properties :
+ - compatible : "cellwise,cw2015"
+ - cellwise,bat-config-info : Binary battery info blob
+
+Optional properties :
+ - cellwise,monitor-interval : Measurement interval in seconds
+ - cellwise,voltage-divider : Voltage divider for multi-cell packs,
+ specified as two integer values <high side>, <low side> in ohms.
+ - cellwise,virtual-power : Default to disconnected battery state (gauge in pack mode)
+ - cellwise,design-capacity : Design capacity of the battery cell in milliampere hours
+ - cellwise,alert-level : Low battery alarm level in percent
+
+Example:
+ cw2015@62 {
+ status = "okay";
+ compatible = "cellwise,cw201x";
+ reg = <0x62>;
+ cellwise,bat-config-info = <
