power: supply: Add AC driver for Surface Aggregator Module

2021-04-08T12:30:35+00:00

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
status/information via the aforementioned interface on said Surface
models.

power: supply: Add support for RN5T618/RC5T619 charger and fuel gauge

2020-08-28T15:34:38+00:00

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.
