+Qualcomm's QPNP PMIC Battery Management System driver
+
+QPNP PMIC BMS provides interface to clients to read properties related
+to the battery. It's main function is to calculate 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 BMS driver, both implemented as
+subnodes in the example. These peripherals must not be disabled if the BMS
+device is to enabled:
+- qcom,bms-bms : The main BMS device. Supports battery monitoring controls and
+		sensors.
+- qcom,bms-iadc : The BMS IADC peripheral in the IADC device. This is required
+		to determine whether the BMS is using an internal or external
+		rsense to accumulate the Coulomb Counter and read current.
+
+Parent node required properties:
+- compatible : should be "qcom,qpnp-bms" for the BM driver.
+- qcom,r-sense-uohm : sensor resistance in in micro-ohms.
+- qcom,v-cutoff-uv : cutoff voltage where the battery is considered dead in
+			micro-volts.
+- qcom,max-voltage-uv : maximum voltage for the battery in micro-volts.
+- qcom,r-conn-mohm : connector resistance in milli-ohms.
+- qcom,shutdown-soc-valid-limit : If the ocv upon restart is within this
+			distance of the shutdown ocv, the BMS will try to force
+			the new SoC to the old one to provide charge continuity.
+			That is to say,
+				if (abs(shutdown-soc - current-soc) < limit)
+				then use old SoC.
+- qcom,adjust-soc-low-threshold : The low threshold for when the BMS algorithm
+			starts adjusting. If the estimated SoC is not below
+			this percentage, do not adjust.
+- qcom,ocv-voltage-low-threshold-uv : The low voltage threshold for the
+			"flat portion" of the discharge curve. The bms will not
+			accept new ocvs between these thresholds.
+- qcom,ocv-voltage-high-threshold-uv : The high voltage threshold for
+			the "flat portion" of the discharge curve.
+			The bms will not accept new ocvs between these
+			thresholds.
+- qcom,low-soc-calculate-soc-threshold : The SoC threshold for when
+			the periodic calculate_soc work speeds up. This ensures
+			SoC is updated in userspace constantly when we are near
+			shutdown.
+- qcom,low-voltage-threshold : The battery voltage threshold in micro-volts for
+			when the BMS tries to wake up and hold a wakelock to
+			ensure a clean shutdown.
+- qcom,low-soc-calculate-soc-ms : The time period between subsequent
+			SoC recalculations when the current SoC is below
+			qcom,low-soc-calculate-soc-threshold or when battery
+			voltage is below qcom,low-voltage-threshold.
+- qcom,calculate-soc-ms : The time period between subsequent SoC
+			recalculations when the current SoC is above or equal
+			qcom,low-soc-calculate-soc-threshold.
+- qcom,chg-term-ua : current in micro-amps when charging is considered done.
+			As soon as current passes this point, charging is
+			stopped.
+- qcom,batt-type: Type of battery used. This is an integer that corresponds
+			to the enum defined in
+			include/linux/mfd/pm8xxx/batterydata-lib.h
+- qcom,high-ocv-correction-limit-uv: how much the bms will correct OCV when
+			voltage is above the flat portion of the discharge
+			curve.
+- qcom,low-ocv-correction-limit-uv: how much the bms will correct OCV when
+			voltage is below the flat portion of the discharge
+			curve.
+- qcom,hold-soc-est: if the voltage-based estimated SoC is above this percent,
+			the BMS will clamp SoC to be at least 1.
+- qcom,tm-temp-margin: if the pmic die temperature changes by more than this
+			value, recalibrate the ADCs. The unit of this property
+			is in millidegrees celsius.
+
+Parent node optional properties:
+- qcom,ignore-shutdown-soc: A boolean that controls whether BMS will
+			try to force the startup SoC to be the same as the
+			shutdown SoC. Defining it will make BMS ignore the
+			shutdown SoC.
+- qcom,use-voltage-soc : A boolean that controls whether BMS will use
+			voltage-based SoC instead of a coulomb counter based
+			one. Voltage-based SoC will not guarantee linearity.
+- qcom,use-external-rsense : A boolean that controls whether BMS will use
+			an external sensor resistor instead of the default
+			RDS of the batfet.
+- qcom,use-ocv-thresholds : A boolean that controls whether BMS will take
+			new OCVs only between the defined thresholds.
+
+All sub node required properties:
+- reg : offset and length of the PMIC peripheral register map.
+
+qcom,bms-bms node required properties:
+- interrupts : the interrupt mappings.
+		The format should be
+		<slave-id peripheral-id interrupt-number>.
+- interrupt-names : names for the mapped bms interrupt
+		The following interrupts are required:

+- summit,stat-gpio		gpio which smb350 STAT pin connects to.
+- summit,chg-en-n-gpio		gpio which control charging enable.
+- summit,chg-susp-n-gpio	gpio which control device shutdown
+- summit,chg-current-ma		charging current in milliamps.
+- summit,term-current-ma	charging termination current in milliamps.
+				valid values are 200/300/400/500/600/700.
+				A value of zero means no termination current.
