power: supply: add support for MAX1720x standalone fuel gauge

2024-07-04T08:25:04+00:00

The MAX17201 monitors a single cell pack. The MAX17205 monitors and balances a 2S or 3S pack or monitors a multiple-series cell pack. Both devices use a I2C interface.

power: supply: add ChromeOS EC based charge control driver

2024-07-01T13:22:19+00:00

The ChromeOS Embedded Controller implements a command to control charge thresholds and behaviour. Use it to implement the standard Linux charge_control_start_threshold, charge_control_end_threshold and charge_behaviour sysfs UAPIs. The driver is designed to be probed via the cros_ec mfd device.

power: supply: Add driver for pm8916 lbc

2023-09-15T19:52:00+00:00

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.

power: supply: Add pm8916 VM-BMS support

2023-09-15T19:52:00+00:00

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. This driver implements basic value readout from this block.

Add a driver for the Mitsumi MM8013 fuel gauge. The driver is a vastly cleaned up and improved version of the one that shipped in some obscure Lenovo downstream kernel [1], with some register definitions borrowed from ChromeOS EC platform code [2].

power: supply: add Qualcomm PMI8998 SMB2 Charger driver

2023-06-08T23:20:14+00:00

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.

This patch adds device driver of Richtek RT5033 PMIC. The driver supports switching charger. rt5033 charger provides three charging modes. The charging modes are pre-charge mode, fast charge mode and constant voltage mode. They vary in charge rate, the charge parameters can be controlled by i2c interface.
