1AB85000 PMIC contains a node, which contains shared 2information about the battery connected to the PMIC. 3The node has no compatible property. 4 5Properties of this node are: 6 7thermistor-on-batctrl: 8 A boolean value indicating thermistor interface to battery 9 10 Note: 11 'btemp' and 'batctrl' are the pins interfaced for battery temperature 12 measurement, 'btemp' signal is used when NTC(negative temperature 13 coefficient) resister is interfaced external to battery whereas 14 'batctrl' pin is used when NTC resister is internal to battery. 15 16 Example: 17 ab8500_battery: ab8500_battery { 18 thermistor-on-batctrl; 19 }; 20 indicates: NTC resister is internal to battery, 'batctrl' is used 21 for thermal measurement. 22 23 The absence of property 'thermal-on-batctrl' indicates 24 NTC resister is external to battery and 'btemp' signal is used 25 for thermal measurement. 26 27battery-type: 28 This shall be the battery manufacturing technology type, 29 allowed types are: 30 "UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn" 31 Example: 32 ab8500_battery: ab8500_battery { 33 stericsson,battery-type = "LIPO"; 34 }
