+QTI's QPNP PMIC Fuel Gauge Device
+
+QPNP PMIC FG provides interface to clients to read properties related
+to the battery. Its main function is to retrieve the State of Charge (SOC),
+a 0-100 percentage representing the amount of charge left in the battery.
+
+There are two required peripherals in the FG driver, both implemented as
+subnodes in the example. These peripherals must not be disabled if the FG
+device is to enabled:
+
+- qcom,fg-soc : The main FG device. Supports battery fuel gauge controls and
+ sensors.
+- qcom,fg-batt : The FG battery device supports interrupts and controls with
+ respect to the state of the connected battery.For example: the
+ peripheral informs the driver if the battery has been identified
+ by the fuel gauge based on a given battery resistance range.
+
+Optionally ADC nodes can be added
+- qcom,revid-tp-rev: A subnode with a register address for the TP_REV register
+ in the REVID peripheral. This is used to apply workarounds that
+ may depend on the trim program.
+- qcom,fg-adc-vbat : A subnode with a register address for the FG_ADC_USR
+ peripheral which is used mainly for battery current limiting (BCL).
+ This node maps out the VBAT reading register which allows to have
+ a +/- 32 mV accurate reading of VBAT.
+- qcom,fg-adc-ibat : A subnode with a register address for the FG_ADC_USR
+ peripheral which is used mainly for battery current limiting (BCL).
+ This node maps out the IBAT current reading register which allows
+ to have a +/- 32 mA accurate reading of IBAT.
+
+Parent node required properties:
+- compatible : should be "qcom,qpnp-fg" for the FG driver.
+- qcom,pmic-revid : Should specify the phandle of PMIC
+ revid module. This is used to identify
+ the PMIC subtype.
+
+Parent node optional properties:
+- qcom,warm-bat-decidegc: Warm battery temperature in decidegC.
+- qcom,cool-bat-decidegc: Cool battery temperature in decidegC.
+- qcom,hot-bat-decidegc: Hot battery temperature in decidegC.
+- qcom,cold-bat-decidegc: Cold battery temperature in decidegC.
+- qcom,cold-hot-jeita-hysteresis: A tuple of 2. Index[0] is cold
+ hysteresis and index[1] is hot
+ hysterisis(in decidegC).
+- qcom,ext-sense-type: Current sense channel used by the FG.
+ Set this to use external rsense.
+- qcom,thermal-coefficients: Byte array of thermal coefficients for
+ reading battery thermistor. This should
+ be exactly 6 bytes in length.
+ Example: [01 02 03 04 05 06]
+- qcom,resume-soc: soc to resume charging in percentage.
+- qcom,resume-soc-raw: soc to resume charging in the scale of
+ [0-255]. This overrides qcom,resume-soc
+ if defined.
+- qcom,hold-soc-while-full: A boolean property that when defined
+ holds SOC at 100% when the battery is
+ full.
+- qcom,bcl-lm-threshold-ma: BCL LPM to MPM mode transition threshold
+ in milliAmpere.
+- qcom,bcl-mh-threshold-ma: BCL MPM to HPM mode transition threshold
+ in milliAmpere.
+- qcom,use-otp-profile: Specify this flag to avoid RAM loading
+ any battery profile.
+- qcom,sw-rbias-control: Boolean property which defines whether
+ the Rbias needs to be controlled by
+ software. If this is not set, it will
+ be controlled by hardware (default).
+- qcom,fg-iterm-ma: Battery current at which the fuel gauge
+ will try to scale 100% towards. When
+ the charge current goes above this, the
+ SoC should be at 100%.
+- qcom,fg-chg-iterm-ma: Battery current at which the fuel gauge
+ will issue end of charge if the charger
+ is configured to use the fuel gauge
+ ADCs for end of charge detection. This
+ property is in milliamps and should be
+ positive (e.g. 100mA to terminate at
+ -100mA).
+- qcom,irq-volt-empty-mv: The voltage threshold that the empty
+ soc interrupt will be triggered. When
+ the empty soc interrupt fires, battery
+ soc will be pulled to 0 and the
+ userspace will be notified via the
+ power supply framework. The userspace
+ will read 0% soc and immediately
+ shutdown.
+- qcom,fg-cutoff-voltage-mv: The voltage where the fuel gauge will
+ steer the SOC to be zero. For example,
+ if the cutoff voltage is set to 3400mv,
+ the fuel gauge will try to count SoC so
+ that the battery SoC will be 0 when it
+ is 3400mV.
+- qcom,fg-vbat-estimate-diff-mv: If the estimated voltage based on SoC
+ and battery current/resistance differs
+ from the actual voltage by more than
+ this amount, the fuel gauge will
+ redo the first SoC estimate when the
+ driver probes.
+- qcom,fg-delta-soc: How many percent the monotonic SoC must
+ change before a new delta_soc interrupt
+ is asserted. If this value is raised
+ above 3-4, some period workarounds may
+ not function well, so it's best to
+ leave this at 1 or 2%.
+- qcom,fg-vbatt-low-threshold: Voltage (in mV) which upon set will be
+ used for configuring the low battery
+ voltage threshold. Interrupt will be
+ asserted and handled based upon
+ this. If this property is not specified,
+ low battery voltage threshold will be
+ configured to 4200 mV.
+- qcom,cycle-counter-en: Boolean property which enables the cycle
+ counter feature. If this property is
+ present, then the following properties
+ to specify low and high soc thresholds
+ should be defined.
+- qcom,capacity-learning-on: A boolean property to have the fuel
+ gauge driver attempt to learn the
+ battery capacity when charging. Takes
+ precedence over capacity-estimation-on.
+- qcom,capacity-learning-feedback: A boolean property to have the fuel
+ gauge driver to feedback the learned
+ capacity into the capacity learning
+ algorithm. This has to be used only if
+ the property "qcom,capacity-learning-on"
+ is specified.
+- qcom,cl-max-increment-deciperc: The maximum percent that the capacity
+ can rise as the result of a single
+ charge cycle. This property corresponds
+ to .1% increments.
+- qcom,cl-max-decrement-deciperc: The maximum percent that the capacity
+ can fall as the result of a single
+ charge cycle. This property corresponds
+ to .1% decrements.
+- qcom,cl-max-temp-decidegc: Above this temperature, capacity
+ learning will be canceled.
+- qcom,cl-mix-temp-decidegc: Below this temperature, capacity
+ learning will be canceled.
+- qcom,cl-max-start-soc: The battery soc has to be below this
+ value at the start of a charge cycle
+ for capacity learning to be run.
+- qcom,cl-vbat-est-thr-uv: The maximum difference between the
+ battery voltage shadow and the current
+ predicted voltage in uV to initiate
+ capacity learning.
+- qcom,capacity-estimation-on: A boolean property to have the fuel
+ gauge driver attempt to estimate the
+ battery capacity using battery
+ resistance.
+- qcom,aging-eval-current-ma: Current used to evaluate battery aging.
+ This value should be around the steady
+ state current drawn from the battery
+ when the phone is low on battery.
+- qcom,fg-cc-cv-threshold-mv: Voltage threshold in mV for configuring
+ constant charge (CC) to constant
+ voltage (CV) setpoint in FG upon
+ which the battery EOC status will
+ be determined. This value should be
+ 10 mV less than the float voltage
+ configured in the charger.
+ This property should only be specified
+ if "qcom,autoadjust-vfloat" property is
+ specified in the charger driver to
+ ensure a proper operation.
+- qcom,bad-battery-detection-enable: A boolean property to enable the fuel
+ gauge driver to detect the damaged battery
+ when the safety-timer expires by using the
+ coulomb count.
+- qcom,fg-therm-delay-us: The time in microseconds to delay battery
+ thermistor biasing.
+- qcom,esr-pulse-tuning-en: A boolean property to enable ESR pulse
+ tuning feature. If this is enabled,
+ ESR pulse extraction will be disabled
+ when state of charge (SOC) is less than
+ 2%. It will be enabled back when SOC
+ gets above 2%. In addition, for SOC
+ between 2% and 5%, ESR pulse timing
+ settings will be different from default.
+ Once SOC crosses 5%, ESR pulse timings
+ will be restored back to default.
+
+qcom,fg-soc node required properties:

+ means that no charge cycle timeout is used and
+ charging can continue indefinitely.
+- qcom,precharging-timeout-mins Maximum duration in minutes that a single
+ precharge cycle may last. Supported values
+ are: 0, 24, 48, 96, 192. A value of 0 means

+ draw for Wipower.
+- qcom,wipower-div2-ilim-map
+- qcom,wipower-pt-ilim-map
+- qcom,wipower-default-ilim-map
+ Array of 5 elements to indicate the voltage ranges and their corresponding
+ current limits. The 5 elements with index [0..4] are:
+ [0] => voltage_low in uV
+ [1] => voltage_high in uV
+ [2] => current limit for pass through in mA
+ [3] => current limit for div2 mode dcin low voltage in mA
+ [4] => current limit for div2 mode dcin high voltage in mA
+ The div2 and pt tables indicate the current limits
+ to use when Wipower is operating in divide_by_2 mode
+ and pass through mode respectively.
+ The default table is used when the voltage ranges
+ are beyond the ones specified in the mapping table.
+ Note that if dcin-vadc or any of these mapping
+ tables are not specified, dynamic dcin input
+ is disabled.
+- qcom,charging-disabled Set this if charging should be disabled in the
+ build by default.
+- qcom,resume-delta-mv Specifies the minimum voltage drop in
+ millivolts below the float voltage that is
+ required in order to initiate a new charging
+ cycle. Supported values are: 50, 100, 200 and
+ 300mV.
+- qcom,chg-inhibit-en Boolean that indicates whether the charge inhibit
+ feature needs to be enabled. If this is not set,
+ charge inhibit feature is disabled by default.
+- qcom,chg-inhibit-fg Indicates if the recharge threshold source has
+ to be Fuel gauge ADC. If this is not set, it
+ will be analog sensor by default.
+- qcom,bmd-algo-disabled Indicates if the battery missing detection
+ algorithm is disabled. If this node is present
+ SMB uses the THERM pin for battery missing
+ detection.
+- qcom,charge-unknown-battery Boolean that indicates whether an unknown
+ battery without a matching profile will be
+ charged. If this is not set, if the fuel gauge
+ does not recognize the battery based on its
+ battery ID, the charger will not start
+ charging.
+- qcom,bmd-pin-src A string that indicates the source pin for the
+ battery missind detection. This can be either:
+ - "bpd_none"
+ battery is considered always present
+ - "bpd_id"
+ battery id pin is used
+ - "bpd_thm"
+ battery therm pin is used
+ - "bpd_thm_id"
+ both pins are used (battery is
+ considered missing if either pin is
+ floating).
+- qcom,iterm-ma Specifies the termination current to indicate
+ end-of-charge. Possible values in mA:
+ 50, 100, 150, 200, 250, 300, 500, 600.
+- qcom,iterm-disabled Disables the termination current feature. This
+ is a boolean property.
+- otg-parent-supply A phandle to an external boost regulator for
+ OTG if it exists.
+- qcom,thermal-mitigation: Array of input current limit values for
+ different system thermal mitigation levels.
+ This should be a flat array that denotates the
+ maximum charge current in mA for each thermal
+ level.
+- qcom,rparasitics-uohm: The parasitic resistance of the board following
+ the line from the battery connectors through
+ vph_power. This is used to calculate maximum
+ available current of the battery.
+- qcom,vled-max-uv: The maximum input voltage of the flash leds.
+ This is used to calculate maximum available
+ current of the battery.
+- qcom,autoadjust-vfloat A boolean property that when set, makes the
+ driver automatically readjust vfloat using the
+ fuel gauge ADC readings to make charging more
+ accurate.
+- qcom,jeita-temp-hard-limit property when present will enable or disable
+ the jeita temperature hard limit based on the
+ value 1 or 0. Specify 0 if the jeita temp hard
+ limit needs to be disabled. If it is not present,
+ jeita temperature hard limit will be based on what
+ the bootloader had set earlier.
+- qcom,low-volt-dcin: A boolean property which upon set will enable the
+ AICL deglitch configuration dynamically. This needs
+ to be set if the DCIN supply is going to be less
+ than or equal to 5V.
+- qcom,force-aicl-rerun: A boolean property which upon set will enable the
+ AICL rerun by default along with the deglitch time
+ configured to long interval (20 ms). Also, specifying
+ this property will not adjust the AICL deglitch time
+ dynamically for handling the battery over-voltage
+ oscillations when the charger is headroom limited.
+- qcom,aicl-rerun-period-s If force-aicl-rerun is on, this property dictates
+ how often aicl is reran in seconds. Possible values
+ are 45, 90, 180, and 360.
+- qcom,ibat-ocp-threshold-ua Maximum current before the battery will trigger
+ overcurrent protection. Use the recommended
+ battery pack value minus some margin.
+- qcom,soft-vfloat-comp-disabled Set this property when the battery is
+ powered via external source and could
+ go above the float voltage.
+- qcom,parallel-usb-min-current-ma Minimum current drawn by the primary
+ charger before enabling the parallel
+ charger if one exists. Do not define
+ this property if no parallel chargers
+ exist.
+- qcom,parallel-usb-9v-min-current-ma Minimum current drawn by the primary
+ charger before enabling the parallel
+ charger if one exists. This property
+ applies only for 9V chargers.
+- qcom,parallel-allowed-lowering-ma Acceptable current drop from the initial limit
+ to keep parallel charger activated. If the
+ charger current reduces beyond this threshold
+ parallel charger is disabled. Must be specified
+ if parallel charger is used.
+- qcom,parallel-main-chg-fcc-percent Percentage of the fast charge current allotted to the
+ main charger when parallel charging is enabled and
+ operational. If this property is not defined, the
+ driver defaults to a 50%/50% split between the main
+ and parallel charger.
+- qcom,parallel-main-chg-icl-percent Percentage of the input current allotted to the
+ main charger when parallel charging is enabled and
+ operational. If this property is not defined, the
+ driver defaults to a 60%/40% split between the main
+ and parallel charger.
+- qcom,battery-data Points to the phandle of node which
+ contains the battery-profiles supported
+ by the charger/FG.
+- qcom,chg-led-support A bool property to support the charger led feature.
+- qcom,chg-led-sw-controls A bool property to allow the software to control
+ the charger led without a valid charger.
+- qcom,skip-usb-notification A boolean property to be used when usb gets present
+ and type from other means. Especially true on
+ liquid hardware, where usb presence is detected based on GPIO.
+- qcom,skip-usb-suspend-for-fake-battery A boolean property to skip
+ suspending USB path for fake
+ battery.
+- qcom,vchg_sns-vadc Phandle of the VADC node.
+- qcom,vchg-adc-channel-id The ADC channel to which the VCHG is routed.
