2024-10-16power: supply: initial support for TWL6030/32Andreas Kemnade
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.

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.

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.

2021-04-08power: supply: Add AC driver for Surface Aggregator ModuleMaximilian Luz
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.

2020-08-28power: supply: Add support for RN5T618/RC5T619 charger and fuel gaugeAndreas Kemnade
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.
