PMM8654AU is a distinct PMIC variant from PMM8650AU despite sharing the
same PMIC subtype. PMM8654AU implements additional registers added to
the "hlos" register address spaces, so add qcom,pmm8654au-pon as a
fallback to qcom,pmk8350-pon to distinguish it from the baseline
PMK8350 PON implementation.

The MAX17042 family binding references the generic power-supply schema,
but additionalProperties only recognizes properties declared directly by
this schema.
Use unevaluatedProperties so generic properties such as monitored-battery
are accepted while unknown properties remain rejected. Remove the local
power-supplies declaration because it is already inherited from
power-supply.yaml.

current-limit controls
Add three optional properties to the MAX8903 charger binding to
describe board-level GPIO control of the DC and USB input current
limits:
DC input (TA / DOK pin):
- dc-current-limit-gpios (1..4 GPIOs): mux control lines feeding
the MAX8903 IDC resistor mux;
- dc-current-limit-mapping (uint32-matrix of {microamps,
gpio_bit_pattern} pairs): the available current levels and the
GPIO bit pattern that selects each level.
USB input (USB / UOK pin):
- usb-current-limit-gpios: a single GPIO driving the IUSB pin.
The IUSB pin is silicon-fixed by the MAX8903 datasheet (Pin
Description): low selects 100 mA, high selects 500 mA. Only
the GPIO mapping is board-specific; the current values are
not exposed in DT.
A dependentRequired block ties dc-current-limit-gpios and
dc-current-limit-mapping together so an incomplete DT cannot pass
validation with only one half of the pair.
These let userspace clamp the input draw via the standard
POWER_SUPPLY_PROP_INPUT_CURRENT_LIMIT power_supply attribute. The HP
TouchPad uses both: two TLMM lines select between 0.5 A, 1.0 A,
1.5 A and 2.0 A DC input current limits behind the MAX8903B
charger, and a third TLMM line picks the IUSB 100 mA / 500 mA
limit.
These are purely additive; existing platforms remain unaffected.

The max17042 binding described "maxim,cold-temp" and
"maxim,over-heat-temp" as unsigned values, but in-tree DTS examples
use negative temperatures such as a cold threshold below zero degrees.
Document the temperature properties as signed int32 values so the
schema matches existing DTS data and the driver can use signed helpers.

There is no use of double colon '::' in YAML. OTOH, the literal style
block, e.g. using '|' treats all characters as content [1] therefore
single use of ':' in descriptions is perfectly fine, whenever '|' is
used.
Cleanup existing code, so the confusing style won't be re-used in new
contributions.

Controller
The A733 PCK600, similar to A523 PCK600, is likely a customized version
of ARM PCK-600 power controller. They share the same BSP drivers in the
package provided by Radxa, with the only difference being the lack of
resets.
Therefore, document A733 compatible and make resets required only for
the other models, as well as prepare the PD definitions for future
device trees.

Allow this standard property here, while also deprecating the existing

The Maxim MAX77759 is a companion PMIC intended for use in mobile
phones and tablets. It is used on Google Pixel 6 and 6 Pro (oriole and
raven). Amongst others, it contains a fuel gauge that is similar to the
ones supported by this binding.
The fuel gauge can measure battery charge and discharge current,
battery voltage, battery temperature, and the Type C connector's
temperature.

On the MediaTek MT8196 SoC, the Mali GPU's "shader_present" hardware
register may also include a non-functional shader core, along with the
present shader cores. An efuse elsewhere in the SoC provides the
shader_present mask with the fused off core omitted.
However, the efuse address is not publicly disclosed. What is known
though is that the GPUEB MCU reads this efuse, and exposes its contents
in the memory it shares with the application processor.
We can therefore describe the mediatek,mt8196-gpufreq device as being an
nvmem provider for this purpose, as it does provide nvmem access in an
indirect way.
The shader-present child node is left out of the list of required
properties as we may one day be able to describe the actual efuse region
this value comes from, so the gpufreq device isn't necessarily the only
device that can provide this cell, and implementations shouldn't need to
implement this functionality once this is the case.

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.
