2023-09-15power: supply: Add driver for pm8916 lbcNikita Travkin
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. This driver implements basic value readout from this block.

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.

2022-02-11power: supply: ug3105_battery: Add driver for uPI uG3105 battery monitorHans de Goede
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.

Add "depends on IOSF_MBI" to CONFIG_AXP288_CHARGER as the changes from commit ed229454856e ("power: supply: axp288-charger: Optimize register reading method") use symbols which are only defined when IOSF_MBI support is enabled.

2021-08-05power: supply: axp288_fuel_gauge: Refresh all registers in one goAndrejus Basovas
The I2C-bus to the XPower AXP288 is shared between the Linux kernel and the SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock" before it may use the bus and while the kernel holds the semaphore the CPU and GPU power-states must not be changed otherwise the system will freeze. This is a complex process, which is quite expensive. This is all done by iosf_mbi_block_punit_i2c_access(). To ensure that no unguarded I2C-bus accesses happen, iosf_mbi_block_punit_i2c_access() gets called by the I2C-bus-driver for every I2C transfer. Because this is so expensive it is allowed to call iosf_mbi_block_punit_i2c_access() in a nested fashion, so that higher-level code which does multiple I2C-transfers can call it once for a group of transfers, turning the calls done by the I2C-bus-driver into no-ops. Userspace power-supply API users typically will read all provided properties in one go, refreshing the last read values when power_supply_changed() is called by the driver and/or periodically (e.g. every 2 minutes). The reading of all properties in one go causes the P-Unit semaphore to quickly be taken and released multiple times in a row. Certain PMIC registers like AXP20X_FG_RES are even used in multiple properties so they get read multiple times, leading to a P-Unit take + release each time the register is read. As already mentioned the taking of the P-Unit semaphore is a quite expensive operation and it has also been reported that the "hammering" of the P-Unit semaphore done by the axp288_fuel_gauge driver can even cause stability issues with the system as a whole. Switch over to a scheme where the axp288_fuel_gauge driver keeps a local copy of all the registers which it uses for properties and make it only refresh its copy of the registers if the values are older then 1 minute; or when a fuel-gauge interrupt has triggered since the last read. This not only reduces the amount of reads, it also makes the code do all the reads in one go, rather then reading specific registers based on which property is being queried. This allows calling iosf_mbi_block_punit_i2c_access() once before doing all the reads, so that we now only take the P-Unit semaphore once per update.

2021-07-16power: supply: PCHG: Peripheral device chargerDaisuke Nojiri
This patch adds a driver for PCHG (Peripheral CHarGer). PCHG is a framework managing power supplies for peripheral devices. This driver creates a sysfs node for each peripheral charge port: /sys/class/power_supply/peripheral<n> where <n> is the index of a charge port. For example, when a stylus is connected to a NFC/WLC port, the node returns: /sys/class/power_supply/peripheral0/ capacity=50 charge_type=Standard scope=Device status=Charging type=Battery Signed-off-by: Daisuke Nojiri <dnojiri@chromium.org> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
2021-06-04power: supply: rt5033_battery: Fix device tree enumerationStephan Gerhold
The fuel gauge in the RT5033 PMIC has its own I2C bus and interrupt line. Therefore, it is not actually part of the RT5033 MFD and needs its own of_match_table to probe properly. Also, given that it's independent of the MFD, there is actually no need to make the Kconfig depend on MFD_RT5033. Although the driver uses the shared <linux/mfd/rt5033.h> header, there is no compile or runtime dependency on the RT5033 MFD driver.

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.
