Some platforms do not support HVDCP charging. Provide means to
disable them.
Provide a votable for disabling HVDCP in preparation to handle
VBUS and CC line shorted situation.
Note that when hvdcp is disabled, we only disable voltage
negotiations i.e. qc 2.0 detection remains enabled since it
does not need voltage to change.

When a float charger is detected by APSD there are configuration options
that change the behavior of the charger. These options should be
configurable from the device tree. Add a DT parameter "qcom,float-option"
and configure it as follows:
1 - Treat as a DCP
2 - Treat as a SDP
3 - Disable charging
4 - Suspend USB input

Support incoming VCONN Swap requests by accepting and turning
off/on VCONN.
Due to HW board limitations, if VCONN is being sourced from the
VBUS input we cannot support enabling VCONN while as a sink and
greater than 5V has been negotiated on VBUS. In that case, reject
the request. Add a device tree property that indicates whether
the board is configured for separate VCONN supply.

During medium and high discharging scenario, voltage mode
correction needs to be applied so that the battery SOC can
follow closely with the battery voltage. Add support for this
by configuring the ki coefficients for medium and high discharge
current during discharging.

There is a requirement to show battery SOC at 100 when charging
status reaches full as long as the charger is connected and SOC
doesn't drop below automatic recharge threshold. Add support for
this through a device tree property "qcom,hold-soc-while-full".
Also, when charging status reaches full, recharge SOC threshold
need to be adjusted depending on the SOC where termination
happens. This will be more prominent in jeita conditions. Add
support for it.

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.

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).
