We have the charge voltage wrong, it should be 4.35V instead of 4.2V.
This will cause the battery to never get fully charged.
I noticed this when looking at the Andoid kernel battery and charger
status for a fully charged battery:
POWER_SUPPLY_VOLTAGE_NOW=4351000
Also the battery on droid 4 says "4.35, 1735/1785mAh (min/typ),
6.6/6.8 Wh (min/typ)". Presumably the 4.35 on the battery is the
charge voltage.
And finally, on Android the CPCAP CRM register is set to 0x03b5 where
the b is the charge voltage.
Let's fix the charge voltage define and update the charge configuration
to use the 4.35V setting.

It is sensible to assume that the hardware actually always has a
way of charging the battery so when power_supply_am_i_supplied does not
find any suppliers, that does not mean that there are none, but simply
that no power_supply-drivers are registered / bound for any suppliers for
the supply calling power_supply_am_i_supplied.
At which point a fuel-gauge driver calling power_supply_am_i_supplied()
cannot determine whether the battery is being charged or not.
Allow a caller of power_supply_am_i_supplied to differentiate between
there not being any suppliers, vs no suppliers being online by returning
-ENODEV if there are no suppliers matching supplied_to / supplied_from,
which allows fuel-gauge drivers to return POWER_SUPPLY_STATUS_UNKNOWN
rather then POWER_SUPPLY_STATUS_DISCHARGING if there are no suppliers.

On some devices (e.g. GTA04 or OpenPanodra) it can be removed
and even be hot swapped by the user while device continues to operate
through external AC or USB power (as long as system power consumption
remains below ca. 500mA as provided by USB). Under certain conditions
it is possible to boot without battery.
So it makes no sense to check for this situation during probe and make

the battery can be inserted later.

Allow platform-code to disable the reset on probe and suspend/resume
by setting a "disable-reset" boolean device property on the device.
There are several reasons why the platform-code may want to disable
the reset on probe and suspend/resume:
1) Resetting the charger should never be necessary it should always have
sane values programmed. If it is running with invalid values while we
are not running (system turned off or suspended) there is a big problem
as that may lead to overcharging the battery.
2) The reset in suspend() is meant to put the charger back into default
mode, but this is not necessary and not a good idea. If the charger has
been programmed with a higher max charge_current / charge_voltage then
putting it back in default-mode will reset those to the safe power-on
defaults, leading to slower charging, or charging to a lower voltage
(and thus not using the full capacity) while suspended which is
undesirable. Reprogramming the max charge_current / charge_voltage
after the reset will not help here as that will put the charger back
in host mode and start the i2c watchdog if the host then does not do
anything for 40s (iow if we're suspended for more then 40s) the watchdog
expires resetting the device to default-mode, including resetting all
the registers to there safe power-on defaults. So the only way to keep
using custom charge settings while suspending is to keep the charger in
its normal running state with the i2c watchdog disabled. This is fine
as the charger will still automatically switch from constant current
to constant voltage and stop charging when the battery is full.
3) Besides never being necessary resetting the charger also causes
problems on systems where the charge voltage limit is set higher then the
reset value, if this is the case and the charger is reset while charging
and the battery voltage is between the 2 voltages, then about half the
time the charger gets confused and claims to be charging (REG08 contains
0x64) but in reality the charger has decoupled itself from VBUS (Q1 off)
and is drawing 0A from VBUS, leaving the system running from the battery.
This last problem is happening on a GPD-win mini PC with a bq24292i
charger chip combined with a max17047 fuel-gauge and a LiHV battery.
I've checked and TI does not list any errata for the bq24292i which
could explain this (there are no errata at all).

where as the the bq24192[i] has a gpio which should be driven high/low
externally depending on the type of charger connected, from a register
level access pov there is no difference.
The differences between the bq24192 and bq24192i are:
1) Lower default charge rate on the bq24192i
2) Pre-charge-current can be max 640 mA on the bq24192i
On x86/ACPI systems the code which instantiates the i2c client may not
know the exact variant being used, so instead of coding the model-id
in the i2c_id struct and bailing if it does not match, check the reported
model-id matches one of the supported variants.
