Battery driver also can use this attribute just to inform userspace
88
about maximal and minimal voltage thresholds of a given battery.
89
90
+
VOLTAGE_MAX, VOLTAGE_MIN - same as _DESIGN voltage values except that
91
+
these ones should be used if hardware could only guess (measure and
92
+
retain) the thresholds of a given power supply.
93
+
94
CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when
95
battery considered full/empty.
