This driver supports several chip variants which all share the same I2C

under conditions outside of software control (e.g. upon button press or

Hans de Goede f059b46e6f power: supply: ug3105_battery: Add driver for uPI uG3105 battery monitor
Add a new battery driver for the uPI uG3105 battery monitor.

Note the uG3105 is not a full-featured autonomous fuel-gauge. Instead it
is expected to be use in combination with some always on microcontroller
reading its coulomb-counter before it can wrap (must be read every 400
seconds!).

Since Linux does not monitor coulomb-counter changes while the device is
off or suspended, the coulomb counter is not used atm.

So far this driver is only used on x86/ACPI (non devicetree) devs
(also note there is no of_match table). Therefor there is no devicetree
bindings documentation for this driver's "upisemi,rsns-microohm" property
since this is not used in actual devicetree files and the dt bindings
maintainers have requested properties with no actual dt users to
_not_ be added to the dt bindings.

The property's name has been chosen so that it should not need to be
changed if/when devicetree enumeration support gets added later, as it
mirrors "maxim,rsns-microohm" from the "maxim,max17042" bindings.

Andrejus Basovas 394088f0b0 power: supply: axp288_fuel_gauge: Refresh all registers in one go
The I2C-bus to the XPower AXP288 is shared between the Linux kernel and
the SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock"
before it may use the bus and while the kernel holds the semaphore the CPU
and GPU power-states must not be changed otherwise the system will freeze.

This is a complex process, which is quite expensive. This is all done by
iosf_mbi_block_punit_i2c_access(). To ensure that no unguarded I2C-bus
accesses happen, iosf_mbi_block_punit_i2c_access() gets called by the
I2C-bus-driver for every I2C transfer. Because this is so expensive it
is allowed to call iosf_mbi_block_punit_i2c_access() in a nested
fashion, so that higher-level code which does multiple I2C-transfers can
call it once for a group of transfers, turning the calls done by the
I2C-bus-driver into no-ops.

Userspace power-supply API users typically will read all provided
properties in one go, refreshing the last read values when
power_supply_changed() is called by the driver and/or periodically
(e.g. every 2 minutes).

The reading of all properties in one go causes the P-Unit semaphore
to quickly be taken and released multiple times in a row. Certain
PMIC registers like AXP20X_FG_RES are even used in multiple properties
so they get read multiple times, leading to a P-Unit take + release
each time the register is read.

As already mentioned the taking of the P-Unit semaphore is a quite
expensive operation and it has also been reported that the
"hammering" of the P-Unit semaphore done by the axp288_fuel_gauge
driver can even cause stability issues with the system as a whole.

Switch over to a scheme where the axp288_fuel_gauge driver keeps
a local copy of all the registers which it uses for properties
and make it only refresh its copy of the registers if the values
are older then 1 minute; or when a fuel-gauge interrupt has
triggered since the last read.

This not only reduces the amount of reads, it also makes the code
do all the reads in one go, rather then reading specific registers
based on which property is being queried. This allows calling
iosf_mbi_block_punit_i2c_access() once before doing all the reads,
so that we now only take the P-Unit semaphore once per update.

Daisuke Nojiri 56d629af09 power: supply: PCHG: Peripheral device charger
This patch adds a driver for PCHG (Peripheral CHarGer). PCHG is a
framework managing power supplies for peripheral devices.

This driver creates a sysfs node for each peripheral charge port:

	/sys/class/power_supply/peripheral<n>

where <n> is the index of a charge port.

For example, when a stylus is connected to a NFC/WLC port, the node
returns:

	/sys/class/power_supply/peripheral0/
		capacity=50
		charge_type=Standard
		scope=Device
		status=Charging

Stephan Gerhold f3076cd8d1 power: supply: rt5033_battery: Fix device tree enumeration
The fuel gauge in the RT5033 PMIC has its own I2C bus and interrupt
line. Therefore, it is not actually part of the RT5033 MFD and needs
its own of_match_table to probe properly.

Also, given that it's independent of the MFD, there is actually
no need to make the Kconfig depend on MFD_RT5033. Although the driver
uses the shared <linux/mfd/rt5033.h> header, there is no compile
or runtime dependency on the RT5033 MFD driver.

Maximilian Luz e61ffb3445 power: supply: Add AC driver for Surface Aggregator Module
On newer Microsoft Surface models (specifically 7th-generation, i.e.
Surface Pro 7, Surface Book 3, Surface Laptop 3, and Surface Laptop Go),
battery and AC status/information is no longer handled via standard ACPI
devices, but instead directly via the Surface System Aggregator Module
(SSAM), i.e. the embedded controller on those devices.

While on previous generation models, AC status is also handled via SSAM,
an ACPI shim was present to translate the standard ACPI AC interface to
SSAM requests. The SSAM interface itself, which is modeled closely after
the ACPI interface, has not changed.

This commit introduces a new SSAM client device driver to support AC

Both chips have charger and a fuel gauge.

This adds basic support for displaying the state of the battery and the
input power, settings are not modified. There are some defaults set via
OTP.

Charging also starts after plugging USB.

Known issues of the fuel gauge: There are drivers in the wild which disable
the fuel gauge at shutdown. If a kernel is booted without fuel gauge
support, after such a driver has been used, the fuel gauge will stay off
and decalibrate.
If this driver is used after that, it might display wrong values for charge
level.

power: supply: cros-ec-usbpd-charger: Fix host events
There's a bug on ACPI platforms where host events from the ECPD ACPI
device never make their way to the cros-ec-usbpd-charger driver. This
makes it so the only time the charger driver updates its state is when
user space accesses its sysfs attributes.

Now that these events have been unified into a single notifier chain on
both ACPI and non-ACPI platforms, update the charger driver to use this
new notifier.
