2024-06-12power: sequencing: implement the pwrseq coreBartosz Golaszewski1-0/+1
Implement the power sequencing subsystem allowing devices to share complex powering-up and down procedures. It's split into the consumer and provider parts but does not implement any new DT bindings so that the actual power sequencing is never revealed in the DT representation.

2015-12-08power: Fix unmet dependency on POWER_SUPPLY by POWER_RESET by uncoupling themKrzysztof Kozlowski1-2/+1
Currently the reset/power off handlers (POWER_RESET) and Adaptive Voltage Scaling class (POWER_AVS) are not built when POWER_SUPPLY is disabled. The POWER_RESET is also not visible in drivers main section of config. However they do not really depend on power supply so they can be built always. The objects for power supply drivers already depend on particular Kconfig symbols so there is no need for any changes in drivers/power/Makefile. This allows selecting POWER_RESET from main drivers config section and fixes following build warning (encountered on ARM exynos defconfig when POWER_SUPPLY is disabled manually): warning: (ARCH_HISI && ARCH_INTEGRATOR && ARCH_EXYNOS && ARCH_VEXPRESS && REALVIEW_DT) selects POWER_RESET which has unmet direct dependencies (POWER_SUPPLY) warning: (ARCH_EXYNOS) selects POWER_RESET_SYSCON which has unmet direct dependencies (POWER_SUPPLY && POWER_RESET && OF) warning: (ARCH_EXYNOS) selects POWER_RESET_SYSCON_POWEROFF which has unmet direct dependencies (POWER_SUPPLY && POWER_RESET && OF) Reported-by: Pavel Fedin <p.fedin@samsung.com> Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>

This adds a driver for the usb power_supply bits of the axp20x PMICs. I initially started writing my own driver, before coming aware of Bruno Prémont's excellent earlier RFC with a driver for this. My driver was lacking CURRENT_MAX and VOLTAGE_MIN support Bruno's drvier has, so I've copied the code for those from his driver. Note that the AC-power-supply and battery charger bits will need separate drivers. Each one needs its own devictree child-node so that other devicetree nodes can reference the right power-supply, and thus each one will get its own mfd-cell / platform_device and platform-driver.

2013-08-28bq24190_charger: Add support for TI BQ24190 Battery ChargerMark A. Greer1-0/+6
Add driver support for the Texas Instruments BQ24190 battery charger. Some of the information provided by the device is about the charger and other information is about the battery so create two power_supply objects (one for each) and provide the appropriate information for each one. The device has many fields that go beyond what is reasonable to report or modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver exports the register fields via sysfs. They are prefixed by 'f_' (for 'field') to make it easier to distinguish between a register field and a "normal" sysfs file exported by the power_supply infrastructure. Signed-off-by: Mark A.

2013-08-10power_supply: Make goldfish_battery depend on GOLDFISH || COMPILE_TESTPaul Gortmaker1-1/+1
Nearly all the other goldfish peripherals (mtd, keyboard, etc) have a dependency on the main platform's GOLDFISH Kconfig item, but this one got skipped. Even with consistency as a justification, there was initial resistance[1] from some people to adding it however, as they wanted the extra compile coverage. Now, with CONFIG_COMPILE_TEST, we have the middle ground that will give people the coverage who want it, and let those who don't want it to skip ever seeing the option presented.

Pull battery updates from Anton Vorontsov: "Highlights: - OpenFirmware/DeviceTree support for the Power Supply core: the core now automatically populates supplied_from hierarchy from the device tree. With these patches chargers and batteries can now lookup each other without the board files support shim. Rhyland Klein at NVIDIA did the work - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the AB85xx core and depends on some recent changes to it, so that is why the driver comes through the battery tree. It has an appropriate ack from the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored the driver - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes touch mfd parts, but these were acked by the appropriate MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of the work and lead the submission process.

This patch adds support for the tps65090 charger driver. This driver is responsible for controlling the charger aspect of the tps65090 mfd. Currently, this mainly consists of turning on and off the charger, but some features of the charger can be supported through this driver including: - Enable Auto Recharge based on Battery voltage - Fast Charge Safety Timer - Maximum battery discharge current - Maximum battery adapter current - Enable External Charge - Disable charging termination based on low charger current (supported) Once the driver is accepted, later patches can add support for the features above which are not yet supported.
