charger-manager bindings
~~~~~~~~~~~~~~~~~~~~~~~~
Required properties :
- compatible : "charger-manager"
- <>-supply : for regulator consumer, named according to cm-regulator-name
- 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 - one of USB, USB-HOST,
SDP, DCP, CDP, ACA, FAST-CHARGER, SLOW-CHARGER, WPT,
PD, DOCK, JIG, or MECHANICAL
- 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 - 0 for disabled, 1 for always, 2 for when
external power is connected, or 3 for when charging. If not present,
then polling is disabled
- cm-poll-interval : polling interval (in ms)
- cm-battery-stat : battery status - 0 for battery always present, 1 for no
battery, 2 to check presence via fuel gauge, or 3 to check presence
via charger
- cm-fullbatt-vchkdrop-volt : voltage drop (in uV) before restarting charging
- cm-fullbatt-voltage : voltage (in uV) of full battery
- cm-fullbatt-soc : state of charge to consider as full battery
- cm-fullbatt-capacity : capcity (in uAh) to consider as full battery
- 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
Deprecated properties:
- cm-num-chargers
- cm-fullbatt-vchkdrop-ms
