ROHM has developed a so called "zero-correction" -algorithm to improve
the fuel-gauging accuracy close to the point where battery is depleted.
This relies on battery specific "VDR" (voltage drop rate) tables, which
are measured from the battery, and which describe the voltage drop rate.
More thorough explanation about the "zero correction" and "VDR"
parameters is here:
https://lore.kernel.org/all/676253b9-ff69-7891-1f26-a8b5bb5a421b@fi.rohmeurope.com/
Document the VDR zero-correction specific battery properties used by the
BD71815, BD71828, BD72720 and some other ROHM chargers. (Note, charger
drivers aren't upstream yet).

Some of the chargers for lithium-ion batteries use a trickle-charging as
a first charging phase for very empty batteries, to "wake-up" the battery.
Trickle-charging is a low current, constant current phase. After the
voltage of the very empty battery has reached an upper limit for
trickle charging, the pre-charge phase is started with a higher current.
Allow defining the upper limit for trickle charging voltage, after which
the charging should be changed to the pre-charging.

The term 'trickle-charging' is used to describe a very slow charging
phase, where electrons "trickle-in" the battery.
There are two different use-cases for this type of charging. At least
some Li-Ion batteries can benefit from very slow, constant current,
pre-pre phase 'trickle-charging', if a battery is very empty.
Some other batteries use top-off phase 'trickle-charging', which is
different from the above case.
The battery bindings use the term 'trickle-charge' without specifying
which of the use-cases properties are addressing. This has already
caused some confusion.
Clarify that the 'trickle-charge-current-microamp' refers to the first
one, the "pre-pre" -charging use-case.

Add the vendor specific boolean property of x-powers,no-thermistor.
This property optionally describes hardware where no thermistor is
present on the battery and is specific to the AXP717. In rare
circumstances this value can be set incorrectly in the efuse of the
PMIC, and if it is not hard-coded the device will fail to charge.

current limit
With DT properties charge-current-limit-gpios and
charge-current-limit-mapping one can define charge current limits in uA
using up to 32 GPIOs. Add property charge-current-limit-default-microamp
which selects a default charge current limit that must be listed in
charge-current-limit-mapping.
This is helpful when the smallest possible charge current limit is 0uA. The
driver defaults to the smallest possible value at the moment, which
disables charging on probe. With the default its possible to setup a safe
charge current limit.

The BQ24297 is identical to the BQ24296 except that it uses USB D+ / D-
data-lines for charger-type (max. input-current) detection instead of
a PSEL input pin.
This is the same difference as between the already supported BQ24190
(D+ / D-) and the BQ24192 (PSEL).

Add LTC4162-F/S and LTC4015 to the supported devices of LTC4162-L.
They share a common set of registers. The only differences lie in the
resolution value of the scaling factor for battery voltage and battery
current measurement, input voltage, and input current for different
battery chemistries. The differences also include the calculation of
setting and getting the actual voltage applied to the charge voltage,
as well as getting the die temperature.
This add compatible entries for ltc4162-f/s and ltc4015 and include
datasheets for new devices.

Convert the Spreadtrum SC27xx PMIC bindings to DT schema. Adjust the
filename to match the compatible of the only in-tree user, SC2731.
Change #interrupt-cells value to 1, as according to [1] that is the
correct value.
Move partial examples of child nodes in the child node schemas to this new
MFD schema to have one complete example.

"#interrupt-cells" from example
Enabling dtc interrupt_provider check reveals the example is missing
the "interrupt-controller" property as it is a dependency of
"#interrupt-cells". However, the PMIC parent node is not an interrupt
controller at all, so the "#interrupt-cells" is erroneous.

The SC27XX fuel gauge supports a low voltage alarm IRQ, which is used
for more accurate battery capacity measurements with lower voltages.
This was unfortunately never documented in bindings, do so now.
The only in-tree user (sc2731.dtsi) has had interrupts specified
since its initial fuel-gauge submission and the current kernel
driver returns an error when no interrupt is specified, so also
add it to the required list.

The BQ24296 is most similar to the BQ24196, but the:
1. OTG config is split from CHG config (REG01)
2. ICHG (Fast Charge Current limit) range is smaller (<=3008mA)
3. NTC fault is simplified to 2 bits
