+Summit smb358 battery charger
+
+SMB358 is a single-cell battery charger. It can charge
+the battery and power the system via the USB/AC adapter input.

+
+Required Properties:
+- compatible Must be "qcom,smb358-charger".
+- reg The device 7-bit I2C address.
+- interrupt-parent parent of interrupt.
+- interrupts This indicates the IRQ number of the GPIO
+ connected to the STAT pin.
+- qcom,irq-gpio GPIO which receives interrupts from STAT output.
+- qcom,bms-psy-name This is a string and it points to the bms
+ power supply name.
+- qcom,float-voltage-mv Float Voltage in mV - the maximum voltage up to which
+ the battery is charged. Supported range 3500mV to 4500mV
+- qcom,vcc-i2c-supply Power source required to power up i2c bus.
+- qcom,chg-vadc Corresponding VADC device's phandle.
+

+- qcom,fastchg-current-max-ma Fast Charging current in mA. Supported range is
+ from 200mA to 2000mA.
+- qcom,chg-valid-gpio GPIO which indicates the charger presence.
+ This GPIO is connected to the SYSOK pin.
+- qcom,chg-autonomous-mode This is a bool property and it indicates that the
+ charger is configured for autonomous operation and
+ does not require any software configuration.
+- qcom,disable-apsd This is a bool property which disables automatic
+ power source detection (APSD). If this is set
+ charger detection is done by DCIN UV irq.
+- qcom,charger-disabled This is a bool property which disables charging.
+- qcom,using-pmic-therm This property indicates thermal pin connected to pmic or smb.
+- qcom,iterm-ma Specifies the termination current to indicate end-of-charge.
+ Possible values in mA - 30, 40, 60, 80, 100, 125, 150, 200.
+- qcom,iterm-disabled Disables the termination current feature. This is a bool

+- qcom,recharge-mv Recharge threshold in mV - the offset from the float-volatge
+ as which the charger restarts charging. Possible
+ values are 50mV to 300mV.
+- qcom,recharge-disabled Boolean value which disables the auto-recharge.
+- qcom,chg-adc_tm phandle to the corresponding VADC device to read the ADC channels.
+- qcom,cold-bat-decidegc Cold battery temperature in decidegC.
+- qcom,hot-bat-decidegc Hot battery temperature in decidegC.
+- qcom,bat-present-decidegc This is a property indicating battery present temperature, if
