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.
The smb358 interface is via I2C bus.
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
Optional Properties:
- 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,vcc-i2c-supply           Power source required to power up i2c bus.
- qcom,bms-controlled-charging This property indicates integrating with VMBMS, charger driver and BMS communicates with each other via power_supply
framework. Property "qcom,iterm-disabled" also needs defined
if using this feature to make sure that the charger doesn't terminate charging on its own.
- 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 property.
- 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-inhibit-disabled This is a bool property which disables charger inhibit. Charger inhibit option prevents battery charging upon insertion
of the charger when battery voltage is above the programmed inhibit threshold.
- 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 higher than it, battery should exist. Default value is negative,
if this property is 200, it stands for -200 decidegC.
- qcom,warm-bat-decidegc: Warm battery temperature in decidegC. After hitting this threshold, "qcom,warm-bat-ma" defines maximum charging current and
"qcom,warm-bat-mv" defines maximum target voltage.
- qcom,cool-bat-decidegc:       Cool battery temperature in decidegC. After hitting this threshold, "qcom,cool-bat-ma" defines maximum charging current and
"qcom,cool-bat-mv" defines maximum target voltage.
- qcom,warm-bat-ma: Maximum warm battery charge current in milli-amps.
- qcom,cool-bat-ma: Maximum cool battery charge current in milli-amps.
- qcom,warm-bat-mv: Maximum warm battery target voltage in milli-volts.
- qcom,cool-bat-mv: Maximum cool battery target voltage in milli-volts.
- qcom,chg-vadc Corresponding VADC device's phandle.
- qcom,skip-usb-suspend-for-fake-battery: A boolean property to skip suspending USB path for fake battery. If this property is not present then 'qcom,batt-id-vref-uv' and 'qcom,batt-id-rpullup-kohm' should be present.
- qcom,batt-id-vref-uv The reference voltage on the battery-ID line specified in micro-volts.
- qcom,batt-id-rpullup-kohm The pull-up resistor connected on the battery-ID (vref) line.
- qcom,using-vbat-sns Bool property to indicate that VBAT sense can be done by PMIC.
