We observed that SoC suddenly increase from 98% or 99% to 100%
right after charger removal. This issue caused by charging adjusting
algorithm which adjust SoC to sync 100% with end of charging.
During charging adjustment, the adjusted SoC could be smaller than
original SoC. So when we remove charger, charging adjusting algorithm
stop adjusting SoC and then bms report original SoC which is larger
than before.
Previously, bms driver considered most of this case by using previous
SoC when SoC increase during discharging. But if SoC is 100%, previous
patch doesn't work.
So this patch add SoC 100% case by checking if charger is enabled.

With shared data channel architecture, SLIMBUS driver
only removes slimbus channel when all clients vote to
have channel removed. In case of subsystem restart,
client such as MDM can go down without withdrawing
vote. During CODEC path shutdown, CODEC driver will
receive slimbus slave interrupt in time indicating
port disconnection because slimbus channel has not
be been voted off. Then, CODEC driver blindly
shutdown rest of CODEC path. This results in

During UVLO events the charger hardware may lock up
if it is in hardware clock switching mode.
To fix this add a battery alarm with a lower threshold
that disables hardware clock switching.
When the system is awake the resume callback ensures
that the charger is running off of the 19.2 MhZ clock
which does not allow the charger to lock up. Therefore
if the battery alarm wakes up the device before hitting
UVLO the charger hardware will not be in hardware clock
switching mode.

It was observed that while charging the reported soc sometimes reaches
100% before end of charging happens. At other times it does not reach
100% at end of charge and a abrupt jump to 100% soc happens.
Fix this by linearly increasing soc based on battery charge current
after constant voltage phase is reached. Constant voltage phase is
reached when battery voltage reaches the max value.
Also once constant voltage phase is reached and the voltage or charge
current decreases keep reporting the earlier soc. This could be because
of a transient system load.

The "adjust_soc" algorithm where we change the open circuit voltage
(ocv) in steps so that the state of charge (soc) starts approaching
the estimated soc, causes nonlinearity in the soc curves if an incorrect
resistance value is fed to the algorithm.
As battery ages and temperature changes, it is hard to estimate the
exact battery resistance.
So to fix the nonlinearity, limit the amount by which the ocv is
changed. Make it proportional to the current, i.e. change ocv by
small amounts in light load and let it change by proportionally
large amounts in heavy load situations.
Also, make the point where the soc is adjusted configurable via platform
data instead of forcing it to 25%.

When a strong battery is removed, it was seen that the battery voltage
lines on the phone take about five to six seconds to go below 2.1volts
where the pmic resets all the battery backed registers.
If a new battery is plugged in within this time the driver will force
the shutdown soc on this battery which is incorrect.
Compare the shutdown soc with the calculated soc and if they are
different than a configurable limit, simply discard the shutdown soc
and use the calculated soc.

The dynamic UUC algorithm changes the UUC as load, state of charge and
temperature changes. This uncontrolled behaviour causes unacceptable
jumps in state of charge numbers.
Replace the dynamic UUC algorithm with a simple average current based
UUC. The average current is calculated by remembering the load for last
few (16) samples. Also to maintain a reasonable UUC while charging, a
load of 300mA is assumed.
Note that the first time UUC is calculated we don't have load samples
and in that case the instantaneous current is used.
Since we now don't change the UUC with respect to max possible load
(itest), the usage of this value is removed. Also instead of failure
voltage we introduce cutoff voltage which represents the loaded voltage
by which the battery should be reported 0%.

Currently the code does not have a mechanism to remember the soc
reported just before shutting down and upon restarting the new
soc reported is off from the previous soc value reported.
This change introduces
- a method to save soc in an unused coincell back register: ssbi address
0x107 is not used on 8921 and serves the purpose of storing the soc.
The driver reads this value and uses it to scale the reported soc.
- a method to detect that a battery was removed and perhaps replaced by a
different one. If the battery is found replaced the driver is notified
of the change and it disregards the soc value it read from the backup
register. The charger driver has a battery backed bit (force vref
therm) which it sets in its initialization sequence. Once set the
value remains between restarts, unless the battery is removed. The
default value of this bit is 0. Hence if a zero is detected before
writing to it, battery was removed between restarts - this mechanism
is used to notify the BMS to disregard the soc read from the backup
register.
Note that for this to work correctly the bootloader needs to be updated to
not overwrite register 0x107 upon restart.
