+What:		/sys/class/power_supply/ltc4162-l/charge_status
+Date:		Januari 2021
+KernelVersion:	5.11
+Description:
+		Detailed charge status information as reported by the chip.
+
+		Access: Read
+
+		Valid values:
+			ilim_reg_active
+			thermal_reg_active
+			vin_uvcl_active
+			iin_limit_active
+			constant_current
+			constant_voltage
+			charger_off
+
+What:		/sys/class/power_supply/ltc4162-l/ibat
+Date:		Januari 2021
+KernelVersion:	5.11
+Description:
+		Battery input current as measured by the charger. Negative value
+		means that the battery is discharging.
+
+		Access: Read
+
+		Valid values: Signed value in microamps
+
+What:		/sys/class/power_supply/ltc4162-l/vbat
+Date:		Januari 2021
+KernelVersion:	5.11
+Description:
+		Battery voltage as measured by the charger.
+
+		Access: Read
+
+		Valid values: In microvolts
+
+What:		/sys/class/power_supply/ltc4162-l/vbat_avg
+Date:		Januari 2021
+KernelVersion:	5.11
+Description:
+		Battery voltage, averaged over time, as measured by the charger.
+
+		Access: Read
+
+		Valid values: In microvolts
+
+What:		/sys/class/power_supply/ltc4162-l/force_telemetry
+Date:		Januari 2021
+KernelVersion:	5.11
+Description:
+		To save battery current, the measurement system is disabled if
+		the battery is the only source of power. This affects all
+		voltage, current and temperature measurements.
+		Write a "1" to this to keep performing telemetry once every few
+		seconds, even when running on battery (as reported by the online
+		property, which is "1" when external power is available and "0"
+		when the system runs on battery).
+
+		Access: Read, Write
+
+		Valid values: 0 (disabled) or 1 (enabled)
+
+What:		/sys/class/power_supply/ltc4162-l/arm_ship_mode
+Date:		Januari 2021
+KernelVersion:	5.11
+Description:
+		The charger will normally drain the battery while inactive,
+		typically drawing about 54 microamps. Write a "1" to this
+		property to arm a special "ship" mode that extends shelf life
+		by reducing the leakage to about 2.8 microamps. The chip will
+		remain in this mode (and no longer respond to I2C commands)
+		until some external power-supply is attached raising the input
+		voltage above 1V. It will then automatically revert to "0".
+		Writing a "0" to the property cancels the "ship" mode request.
+		The ship mode, when armed, activates once the input voltage
+		drops below 1V.

+		Access: Read, Write

+		Valid values: 0 (disable) or 1 (enable)
