2023-09-15power: supply: Add driver for pm8916 lbcNikita Travkin1-0/+1
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.

This driver adds basic support for VM-BMS found in pm8916. VM-BMS is a very basic fuel-gauge hardware block that is, sadly, incapable of any gauging. The hardware supports measuring OCV in sleep mode, where the battery is not in use, or measuring average voltage over time when the device is active.

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.

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.

2020-08-28power: supply: Add support for RN5T618/RC5T619 charger and fuel gaugeAndreas Kemnade1-0/+1
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. Signed-off-by: Andreas Kemnade <[email protected]> Signed-off-by: Sebastian Reichel <[email protected]>
