commit 90adf98d9530054b8e665ba5a928de4307231d84 upstream.
Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail.

OTG has higher priority than wireless charging, we need to:
1. bypass wireless irq work when OTG is plugged
2. report wireless online = 0 when using wireless charging then
plugging OTG
or it will show charging icon even battery status is "Not Charging"

Average current drawn can be calculated by reading the coulomb
counter based charge before and after the usecase is run and
dividing the difference in the charge by the time it took to
run the usecase.
Use power supply property POWER_SUPPLY_PROP_CHARGE_NOW, to
expose the coulomb counter based charge.

During charging adjustment, the measurement of voltage is not accurate.
Since the measured voltage during charging adjustment is not OCV
(open circuit voltage), it cannot show real battery voltage at CC to CV
point. But current implementation use inaccurate voltage as a voltage of
CC to CV point. This inaccurate voltage of CC to CV point can cause
wrong SoC adjusting. For instance, the SoC could stick at fixed value
until end of charging.
This patch increase accuracy of voltage measurement by using battery
current and battery resister.

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.
