~~~~~~~~~~~~~~~~~~~~~~~~

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
