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	}
