+AB8500 Battery Termperature Monitor Driver
+
+AB8500 is a mixed signal multimedia and power management
+device comprising: power and energy management module,
+WalliCharger and USB charger interface, audio, general
+purpose ADC TVOut, clock management and SIM card Interface.
+
+Battery temperature monitoring support is part of 'energy
+management module', the other components of this module
+are: 'main and USB Combo charger' and fuel guage.
+
+The properties below describes the node for battery
+temperature monitor driver.
+
+Required Properties:
+- compatible = "stericsson,ab8500-btemp"
+
+interrupts:
+ Four battery temperature ranges are be defined
+ which results in interrupt events as:
+ - Btemp
+ - BtempLow
+ - BtempMedium
+ - BtempHigh
+
+
+Supplied-to:
+ This shall be power supply class dependency where in the runtime battery
+ properties will be shared across fuel guage and charging algorithm driver.
+
+Thermister-interface:
+ 'btemp' and 'batctrl' are the pins interfaced for battery temperature
+ measurement, btemp is used when NTC(Negative Termperature coefficient)
+ resister is interfaced external to battery and batctrl is used when
+ NTC resister is internal to battery.
+
+example:
+ab8500-btemp {
+ compatible = "stericsson,ab8500-btemp";
+
+ interrupt-names =
+ "BAT_CTRL_INDB", /* battery removal indicator */
+ "BTEMP_LOW", /* Btemp < BtempLow, if battery temperature is lower than -10°C */
+ "BTEMP_HIGH", /* BtempLow < Btemp < BtempMedium,
+ if battery temperature is between -10 and 0°C */
+ "BTEMP_LOW_MEDIUM", /* BtempMedium < Btemp < BtempHigh,
+ if battery temperature is between 0°C and “MaxTemp”.*/
+ "BTEMP_MEDIUM_HIGH";/* Btemp > BtempHigh,
+ if battery temperature is higher than “MaxTemp”. */
