When the battery is removed and a strong charger is plugged in,
device will be kept powered. However, because of missing battery
SRAM access over IMA can fail leading to errors. Eventually, the
errors will go away when the battery is inserted again. However,
if the user tries to access SRAM registers or bms power supply
properties, it can cause further errors flooding logs. Handle
this gracefully by returning an error upon battery missing is
detected.

Open circuit voltage and predicted battery voltage are read from
16 bits. However, the real value is present only in 15 bits.
Mask the bit 16 to get the proper readings.

Add a module parameter "fg_restart" to restart the fuel gauge
without loading the battery profile. This will be useful in
geting a fresh SOC estimate whenever required.

Batteries age across the time. Capacity learning is a feature
which uses the hardware autonomous coulomb counter to determine
the actual battery capacity against the advertised full capacity.
This will be useful to determine how much degradation has
happened to the battery. Capacity learning algorithm will start
based on some pre-set conditions like start SOC, battery
temperature and ends when the charging cycle is complete.
Actual capacity will be exposed through charge_full property.

Currently, FG_GEN3 driver loads the battery profile if it finds
out the profile loaded earlier doesn't match with the available
profile. This will be done when the profile integrity bit is
set already. Make this force profile loading as a configurable
parameter through a device tree property.
While at it, add a module parameter to dump the profile contents
conditionally. This will be helpful in debugging.

msoc-full is not used to determine when the battery is full. The charger
will wakeup the device when it has terminated charging indicating that
the battery is full. Disable the msoc-full IRQ as a wakeup source.
The msoc-delta IRQ is used to wakeup the device when the SOC changes
therefore having the bsoc-delta IRQ as a wakeup source is unnecessary.
Disable the bsoc-delta IRQ as a wakeup source.

Currently, delta SOC threshold is written as a 8 bit value but
the encoding is in 11 bits. This will cause the delta SOC
threshold programmed to a lower value causing interrupts to fire
quickly. Change the numerator of delta SOC SRAM parameter so that
the delta SOC threshold will be set correctly. Maximum possible
threshold will be 12.45% (1/2048 * 255).

Based on the battery profile parameters, Vbatt greater than float
voltage and full voltage thresholds needs to be configured. Add
support for the same. Since this needs the battery profile
parameters to be read in advance before the hardware is
initialized, shuffle the code to get battery profile early.

Fix the following issues found in static analysis:
- missing blank lines after declarations
- unnecessary return in a void function
- exporting world writable files is usually an error
- block comments use * on subsequent and trailing lines
- Add DT binding description and vendor prefixe for the
driver.
- Add Linux Foundation copyright markings.
