+SMB135x battery charger
+
+SMB135x is a single-cell switching mode battery charger. It can charge

+
+The smb135x interface is via I2C bus.
+
+Required Properties:
+- compatible: Must be "qcom,smb1356-charger", "qcom,smb1357-charger",
+ "qcom,smb1358-charger" or "qcom,smb1359-charger".

+
+Optional Properties:
+
+- interrupts This indicates the IRQ number of the GPIO
+ connected to the STAT pin.
+- qcom,bms-psy-name the psy name to use for reporting battery capacity. If left
+ unspecified it uses a preprogrammed default value.
+- qcom,float-voltage-mv Float Voltage in mV - the maximum voltage up to which
+ the battery is charged. Supported range 3600mV to 4500mV
+- qcom,charging-timeout Maximum duration in minutes that a single charge
+ cycle may last. Supported values are: 0, 192, 384,
+ 768, and 1536. A value of 0 means that no
+ charge cycle timeout is used and charging can
+ continue indefinitely.
+- qcom,dc-psy-type The type of charger connected to the DC path.
+ Can be "Mains" or "Wireless"
+- qcom,dc-psy-ma The current in mA dc path can support. Must be specified if
+ dc-psy-type is specified. Valid range 300mA to 2000mA.

+ by default. Useful in usecases where battery current
+ needs to be profiled even when USB is present.
+- qcom,recharge-thresh-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.

+ property.
+- qcom,soft-vfloat-comp-disabled Set this property when the battery is powered via external

+ that reverse boost.

+ if battery temperature exceeds soft JEITA thresholds.
+- qcom,gamma-setting Array of gamma values for JEITA. The sequence is
+ <"Cold Hard" "Hot Hard" "Cold Soft" "Hot Soft">. Gamma value
+ indicates the ratio of the pull up resistors and NTC
+ resistor in battery pack. There are 4 options referring to

+- qcom,parallel-charger: A flag to indicate if the charger merely assists for USB
+ charging. In this case the input current from USB is split

+ of high current charging from USB path.
+- qcom,inhibit-disabled: Disables the charger-inhibit function.
+- qcom,bms-controlled-charging: This property enables BMS to control EOC and

+ SMB135X is a dual path switching mode charger capable of charging
+ the battery with 3Amps of current.
+ The driver supports charger enable/disable.
+ The driver reports the charger status via the power supply framework.
+ A charger status change triggers an IRQ via the device STAT pin.

+ The driver supports charging control (enable/disable) and
+ charge-current limiting. It also provides USB VBUS detection and
+ notification support. The driver controls SMB1351 via I2C and
+ supports device-tree interface.

+ The QPNP SMB2 charger driver supports the charger peripheral
+ present in the PMICOBALT chip.
+ The power supply framework is used to communicate battery and
+ usb properties to userspace and other driver consumers such
+ as fuel gauge, USB, and USB-PD.
+ VBUS and VCONN regulators are registered for supporting OTG,
+ and powered Type-C cables respectively.

+ The driver supports charger enable/disable.
+ The driver reports the charger status via the power supply framework.
+ A charger status change triggers an IRQ via the device STAT pin.
