6*eb917497SSebastian Reichel
7*eb917497SSebastian Reichelthermistor-on-batctrl:
8*eb917497SSebastian Reichel	A boolean value indicating thermistor interface	to battery
9*eb917497SSebastian Reichel
10*eb917497SSebastian Reichel	Note:
11*eb917497SSebastian Reichel	'btemp' and 'batctrl' are the pins interfaced for battery temperature
12*eb917497SSebastian Reichel	measurement, 'btemp' signal is used when NTC(negative temperature
13*eb917497SSebastian Reichel	coefficient) resister is interfaced external to battery whereas
14*eb917497SSebastian Reichel	'batctrl' pin is used when NTC resister is internal to battery.
15*eb917497SSebastian Reichel
16*eb917497SSebastian Reichel	Example:
17*eb917497SSebastian Reichel	ab8500_battery: ab8500_battery {
18*eb917497SSebastian Reichel		thermistor-on-batctrl;
19*eb917497SSebastian Reichel	};
20*eb917497SSebastian Reichel	indicates: NTC resister is internal to battery, 'batctrl' is used
21*eb917497SSebastian Reichel		for thermal measurement.
22*eb917497SSebastian Reichel
23*eb917497SSebastian Reichel	The absence of property 'thermal-on-batctrl' indicates
24*eb917497SSebastian Reichel	NTC resister is external to battery and  'btemp' signal is used
25*eb917497SSebastian Reichel	for thermal measurement.

27*eb917497SSebastian Reichelbattery-type:
28*eb917497SSebastian Reichel	This shall be the battery manufacturing technology type,
29*eb917497SSebastian Reichel	allowed types are:
30*eb917497SSebastian Reichel		"UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn"
31*eb917497SSebastian Reichel	Example:
32*eb917497SSebastian Reichel	ab8500_battery: ab8500_battery {
33*eb917497SSebastian Reichel		stericsson,battery-type = "LIPO";
