-=== AB8500 Fuel Gauge Driver ===
-
-AB8500 is a mixed signal multimedia and power management
-device comprising: power and energy-management-module,
-wall-charger, usb-charger, audio codec, general purpose adc,
-tvout, clock management and sim card interface.
-
-Fuelgauge support is part of energy-management-modules, other
-components of this module are:
-main-charger, usb-combo-charger and battery-temperature-monitoring.
-
-The properties below describes the node for fuelgauge driver.
-
-Required Properties:
-- compatible = This shall be: "stericsson,ab8500-fg"
-- battery = Shall be battery specific information
- Example:
- ab8500_fg {
- compatible = "stericsson,ab8500-fg";
- battery = <&ab8500_battery>;
- };
-
-dependent node:
- ab8500_battery: ab8500_battery {
- };
- This node will provide information on 'thermistor interface' and
- 'battery technology type' used.
-
-Properties of this node are:
-thermistor-on-batctrl:
- A boolean value indicating thermistor interface to battery
-
- Note:
- 'btemp' and 'batctrl' are the pins interfaced for battery temperature
- measurement, 'btemp' signal is used when NTC(negative temperature
- coefficient) resister is interfaced external to battery whereas
- 'batctrl' pin is used when NTC resister is internal to battery.
-
- Example:
- ab8500_battery: ab8500_battery {
- thermistor-on-batctrl;
- };
- indicates: NTC resister is internal to battery, 'batctrl' is used
- for thermal measurement.
-
- The absence of property 'thermal-on-batctrl' indicates
- NTC resister is external to battery and 'btemp' signal is used
- for thermal measurement.
-
-battery-type:
- This shall be the battery manufacturing technology type,
- allowed types are:
- "UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn"
- Example:
- ab8500_battery: ab8500_battery {
- stericsson,battery-type = "LIPO";
- }
