Add support for RT9756 smart cap divider charger.
The RT9759 is a high efficiency and high charge current charger. The
maximum charge current is up to 8A. It integrates a dual-phase charge
pump core with ADC monitoring.

Add charger driver for ROHM BD718(15/28/78) PMIC charger block.
It is a stripped down version of the driver here:
https://lore.kernel.org/lkml/dbd97c1b0d715aa35a8b4d79741e433d97c562aa.1637061794.git.matti.vaittinen@fi.rohmeurope.com/
For the ease of review and to do a step-by-step approach remove all the
coloumb counter related stuff and do not sneak in BD71827 support. That
also avoids non-trivial rebasing of the above series.
Changes besides that:
Replace the custom property by a standard one and do not use megaohms
for the current sense resistor.

Intel has 2 completely different "Dollar Cove" PMICs for its Bay Trail /
Cherry Trail SoCs. One is made by X-Powers and is called the AXP288.
The AXP288's builtin charger and fuel-gauge functions are already
supported by the axp288_charger / axp288_fuel_gauge drivers.
The other "Dollar Cove" PMIC is made by TI and does not have any clear TI
denomination, its MFD driver calls it the "Intel Dollar Cove TI PMIC".
The Intel Dollar Cove TI PMIC comes with a coulomb-counters with limited
functionality which is intended to work together with an always on
micro-controller monitoring it for fuel-gauge functionality.
Most devices with the Dollar Cove TI PMIC have full-featured fuel-gauge
functionality exposed through ACPI with the information coming from either
the embedded-controller or a separate full-featured fuel-gauge IC.
But some designs lack this, add a battery-monitoring driver using the
PMIC's coulomb-counter combined with the adc-battery-helper for capacity
estimation for these designs.
Register definitions were taken from kernel/drivers/platform/x86/dc_ti_cc.c
from the Acer A1-840 Android kernel source-code archive named:
"App. Guide_Acer_20151221_A_A.zip"
which is distributed by Acer from the Acer A1-840 support page:

Switch ug3105_battery to using the new adc-battery-helper, since the

The TI PMIC used on some Intel Bay/Cherry Trail systems has some builtin
fuel-gauge functionality which just like the UG3105 fuel-gauge is not
a full featured autonomous fuel-gauge.
These fuel-gauges offer accurate current and voltage measurements but
their coulomb-counters are intended to work together with an always on
micro-controller monitoring the fuel-gauge.
Add an adc-battery-helper offering open-circuit-voltage (ocv) and through
that capacity estimation for devices where such limited functionality
fuel-gauges are exposed directly to Linux.
This is a copy of the existing UG3105 estimating code, generalized so that
it can be re-used in other drivers.
The next commit will replace the UG3105 driver's version of this code with
using the adc-battery-helper.
The API has been designed for easy integration into existing power-supply
drivers. For example this functionality might also be a useful addition
to the generic-adc-battery driver.
The requirement of needing the adc_battery_helper struct to be the first
member of a battery driver's data struct is not ideal. This is a compromise
which is necessary to allow directly using the helper's get_property(),
external_power_changed() and suspend()/resume() functions as power-supply /
suspend-resume callbacks.

Add a driver for the charger in the TWL6030/32. For now it does not report
much in sysfs but parameters are set up for USB, charging is enabled with
the specified parameters. It stops charging when full and also restarts
charging.
This prevents ending up in a system setup where you run out of battery
although a charger is plugged in after precharge completed.
Battery voltage behavior was checked via the GPADC.

pm8916 LBC is a Linear Battery Charger hardware block in pm8916 PMIC.
This block implements simple CC/CV charging for Li-Po batteries.
The hardware has internal state machine to switch between modes and
works mostly autonomously, only needing the limits and targets to be
set to operate.
This driver allows setting limits and enabling the LBC block, monitoring
it's state.

Add a driver for the SMB2 charger block found in the Qualcomm PMI8998
and PM660.
This driver is capable of utilising Qualcomm's Automatic Power Source
Detection (APSD) BC1.2 implementation, as well as Automatic Input
Current Limiting (AICL) to configure the maximum input current
limit of DCP (wall) chargers.
Quick Charge is not currently supported.
Most devices using the smb2 charger have a secondary dedicated charger
chip which is used in parallel to enable faster charger without
overheating. However, not all do, as a result to ensure safety until
these are supported, the maximum current is limited to ~1A via the
FAST_CHARGE_CURRENT_CFG register.

This patch adds device driver of Richtek RT5033 PMIC. The driver supports
switching charger. rt5033 charger provides three charging modes. The charging
modes are pre-charge mode, fast charge mode and constant voltage mode. They
vary in charge rate, the charge parameters can be controlled by i2c interface.

The PMIC GLINK service, running on a coprocessor of modern Qualcomm
platforms, deals with battery charging and fuel gauging, as well as
reporting status of AC and wireless power supplies.
As this is just one of the functionalities provided by the PMIC GLINK
service, this power supply driver is implemented as an auxilirary bus
driver, spawned by the main "pmic glink" driver when the PMIC GLINK
service is detected.

RT9467 is a switch-mode single cell Li-Ion/Li-Polymer battery charger
for portable applications.
It integrates a synchronous PWM controller, power MOSFETs,
input current sensing and regulation, high-accuracy voltage regulation,
and charge termination. The charge current is regulated through
integrated sensing resistors.
The RT9467 also features USB On-The-Go (OTG) support. It also integrates
D+/D- pin for USB host/charging port detection.

This driver supports several chip variants which all share the same I2C
register interface. Since the chip will turn off and become inaccessible
under conditions outside of software control (e.g. upon button press or
input voltage removal), some special handling is needed to delay the
initialization of the IC until it is accessible.
