+charger-manager bindings
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Required properties :
+ - compatible : "charger-manager"
+ - <>-supply : for regulator consumer
+ - cm-num-chargers : number of chargers
+ - cm-chargers : name of chargers
+ - cm-fuel-gauge : name of battery fuel gauge
+ - subnode <regulator> :
+ - cm-regulator-name : name of charger regulator
+ - subnode <cable> :
+ - cm-cable-name : name of charger cable
+ - cm-cable-extcon : name of extcon dev
+(optional) - cm-cable-min : minimum current of cable
+(optional) - cm-cable-max : maximum current of cable
+
+Optional properties :
+ - cm-name : charger manager's name (default : "battery")
+ - cm-poll-mode : polling mode (enum polling_modes)
+ - cm-poll-interval : polling interval
+ - cm-battery-stat : battery status (enum data_source)
+ - cm-fullbatt-* : data for full battery checking
+ - cm-thermal-zone : name of external thermometer's thermal zone
+ - cm-battery-* : threshold battery temperature for charging
+ -cold : critical cold temperature of battery for charging
+ -cold-in-minus : flag that cold temperature is in minus degrees
+ -hot : critical hot temperature of battery for charging
+ -temp-diff : temperature difference to allow recharging
+ - cm-dis/charging-max = limits of charging duration
+
