power: supply: add Qualcomm PMI8998 SMB2 Charger driver

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.

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.

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

On newer Microsoft Surface models (specifically 7th-generation, i.e.

devices, but instead directly via the Surface System Aggregator Module

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.
