Add LPG and PWM parameters to blink the red LED. This is controlled by
userspace during charging.
Disable the battery-charging LED triggers to avoid conflicting LED control
by userspace and kernel battery-charging events.

sdm660 CPU CPR controllers support full hardware closed-loop CPR
operation also known as CPR hardening. Extend the cprh-kbss-regulator
driver to handle CPU subsystem specific power requirements of
the sdm660 chip.

As per the hardware documentation, add support for configuring
ESR tight and broad filters for normal and low temperature. This
is needed as the low temperature ESR filter coefficients are not
functional in the hardware.
All the filter values (in terms of percentage) can be configured
through the device tree. When the battery temperature goes below
10 C or user configured temperature threshold, ESR filter values
of room temperature will be applied to ESR low temperature
filters. Once the battery temperature goes above 10 C, original
values will be applied back to ESR low temperature filters.

Battery missing detection interrupt fires prematurely for higher
battery ID values than the desired range. Fix this by disabling
BMD when battery is re-inserted and enable it after obtaining the
battery ID.
While at it, update the battery type shown in particular when a
battery profile is not available.

In certain cases like battery hotswap where a strong charger is
connected and battery is re-inserted, the expectation from the
user is to reload the battery profile. This cannot happen unless
a dVdd reset happens and wipes out FG SRAM. To help with the
aforementioned scenario, clear the profile integrity bit every
time when the battery is re-inserted. This way, FG driver will
reload the profile everytime upon battery insertion.
When the battery is missing, cycle counters cannot be cleared as
the access to FG SRAM might not succeed. Hence remove it from the
battery removal path. It will be cleared anyways when the profile
is loaded after the battery is inserted.
While at it, show the cached value of battery_id instead of
reading it every time from RR_ADC peripheral. When the battery is
re-inserted, battery id is obtained from RR_ADC driver anyways
which is sufficient.

Add support to dump FG SRAM periodically based on the module
parameters. This will be useful for debugging purpose.
To enable FG SRAM dump,
echo 1 > /sys/module/qpnp_fg_gen3/parameters/sram_dump_en
To disable FG SRAM dump,
echo 0 > /sys/module/qpnp_fg_gen3/parameters/sram_dump_en
To set FG SRAM dump period,
echo 15000 > /sys/module/qpnp_fg_gen3/parameters/sram_dump_period_ms
