Qualcomm Techonologies, Inc. QPNP PMIC Fuel Gauge Gen3 Device

QPNP PMIC FG Gen3 device provides interface to the clients to read properties

related to the battery. Its main function is to retrieve the State of Charge

(SOC), in percentage scale representing the amount of charge left in the

battery.

=======================

Required Node Structure

=======================

FG Gen3 device must be described in two levels of device nodes.  The first

level describes the FG Gen3 device.  The second level describes one or more

peripherals managed by FG Gen3 driver. All the peripheral specific parameters

such as base address, interrupts etc., should be under second level node.

====================================

First Level Node - FG Gen3 device

====================================

- compatible

	Usage:      required

	Value type: <string>

	Definition: Should be "qcom,fg-gen3".

- qcom,pmic-revid

	Usage:      required

	Value type: <phandle>

	Definition: Should specify the phandle of PMIC revid module. This is

- qcom,fg-cutoff-voltage

	Usage:      optional

	Value type: <u32>

	Definition: The voltage (in mV) where the fuel gauge will steer the SOC

		    to be zero. For example, if the cutoff voltage is set to

	Value type: <u32>

	Definition: The voltage threshold (in mV) based on which the empty soc

		    interrupt will be triggered. When the empty soc interrupt

		    fires, battery soc will be set to 0 and the userspace will

		    be notified via the power supply framework. The userspace

		    will read 0% soc and immediately shutdown. If this property

		    is not specified, then the default value used will be

- qcom,fg-vbatt-low-thr

	Usage:      optional

	Value type: <u32>

		    the SOC should be at 100%. If this property is not

		    specified, then the default value used will be 125mA.

- qcom,fg-delta-soc-thr

	Usage:      optional

	Value type: <u32>

	Definition: Percentage of monotonic SOC increase upon which the delta

		    SOC interrupt will be triggered. If this property is not

	Value type: <u32>

	Definition: Percentage of monotonic SOC upon which the charging will

		    will be resumed once the charging is complete. If this

		    property is not specified, then the default value will be

	Usage:      optional

	Value type: <u32>

	Definition: Specifies the source of sense resistor.

		    Allowed values are:

	Usage:      optional

	Value type: <prop-encoded-array>

	Definition: A list of integers which holds the jeita thresholds (degC)

		    in the following order. Allowed size is 4.

		    Element 0 - JEITA cold threshold

		    Element 1 - JEITA cool threshold

		    Element 2 - JEITA warm threshold

		    Element 3 - JEITA hot threshold

		    If these parameters are not specified, then the default

		    values used will be 0, 5, 45, 50.
