On SMB, battery termination status updates even when we disable
charging termination. Handle this case by updating the battery status
only if required.

Use power_supply_set_supply_type to notify the charger type
to the USB driver. The charger detection is done by SMB358
instead of the USB driver.

Add an hysteresis offset to prevent irq storm when battery temperature
around JEITA thresholds.

Automatic power source detection is a feature of SMB which can
detect charger type automatically. Fix the register mask to correctly
detect the charger type.

Support JEITA based on PMIC therm. The SMB358 also supports JEITA
configuration in hardware, however in some designs the battery
thermistor is only connected to the PMIC's THERM pin. For such
condition, add the JEITA support using PMIC VADC for thermal reading.
Add some properties to support this feature:
qcom,warm-bat-decidegc
qcom,cool-bat-decidegc
qcom,warm-bat-ma
qcom,cool-bat-ma
qcom,warm-bat-mv
qcom,cool-bat-mv
JEITA only supported when all of these properties are defined.

BMS based termination/recharge allows BMS/FG to control charging.
This is useful in cooperation with voltage mode BMS, where due to
a hardware limitation it's required that the EOC and recharge is
always controlled by BMS module.
The BMS module can independently start/stop charging by writing
the STATUS property of battery power-supply. To enable this feature,
following DT params need to be defined:
qcom,bms-controlled-charging
qcom,iterm-disabled

When battery voltage(Vbatt) is higher than around 4.2v, and
charging is disabled, Charger stops switching. In such a
case, system load is provided by battery rather than input,
even though input is still connected. As a workaround, we need
make reg09[0:3] to be a non-zero value which keeps the switcher
active.

The charger inhibit option prevents battery charging upon
insertion of charger when battery voltage is above the
programmed inhibit threshold.

Call charging enable/disable function explicitly during boot.
It makes sure charging is enabled correctly regardless of the default
setting.

Uninitialized cfg structure may cause random crash when calling
regulator_register() function. Fix this by initializing it to 0
by default.
While at it, fix another minor typo issue.

SMB chip only has a 20-30mV accuracy for VDDMAX. Since it never
meets the 10mV accuracy that BMS expects, taper charging detection
will fail. Fix this by implementing the notification from SMB
driver to BMS driver.

This driver supports external smb358 switch mode charger,
can reach up to 2A charging current. This driver instead of
original qpnp-charger, will co-work with PMIC internal BMS
(Battery Monitor System).
