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
