8c5795fe55278fa6a656bf4a0398fb22d5079298 - power: supply: Add new Intel Dollar Cove TI battery driver

Sun, 31 Aug 2025 14:29:41 +0200

power: supply: Add new Intel Dollar Cove TI battery driverIntel has 2 completely different "Dollar Cove" PMICs for its Bay Trail /Cherry Trail SoCs. One is made by X-Powers and is called the AXP288.The AXP288's builtin charger and fuel-gauge functions are alreadysupported by the axp288_charger / axp288_fuel_gauge drivers.The other "Dollar Cove" PMIC is made by TI and does not have any clear TIdenomination, its MFD driver calls it the "Intel Dollar Cove TI PMIC".The Intel Dollar Cove TI PMIC comes with a coulomb-counters with limitedfunctionality which is intended to work together with an always onmicro-controller monitoring it for fuel-gauge functionality.Most devices with the Dollar Cove TI PMIC have full-featured fuel-gaugefunctionality exposed through ACPI with the information coming from eitherthe embedded-controller or a separate full-featured fuel-gauge IC.But some designs lack this, add a battery-monitoring driver using thePMIC's coulomb-counter combined with the adc-battery-helper for capacityestimation for these designs.Register definitions were taken from kernel/drivers/platform/x86/dc_ti_cc.cfrom the Acer A1-840 Android kernel source-code archive named:"App. Guide_Acer_20151221_A_A.zip"which is distributed by Acer from the Acer A1-840 support page:https://www.acer.com/us-en/support/product-support/A1-840/downloadsReviewed-by: Linus Walleij Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20250831122942.47875-6-hansg@kernel.orgSigned-off-by: Sebastian Reichel List of files: /linux/drivers/power/supply/Makefile

Sun, 31 Aug 2025 14:29:37 +0200

power: supply: Add adc-battery-helperThe TI PMIC used on some Intel Bay/Cherry Trail systems has some builtinfuel-gauge functionality which just like the UG3105 fuel-gauge is nota full featured autonomous fuel-gauge.These fuel-gauges offer accurate current and voltage measurements buttheir coulomb-counters are intended to work together with an always onmicro-controller monitoring the fuel-gauge.Add an adc-battery-helper offering open-circuit-voltage (ocv) and throughthat capacity estimation for devices where such limited functionalityfuel-gauges are exposed directly to Linux.This is a copy of the existing UG3105 estimating code, generalized so thatit can be re-used in other drivers.The next commit will replace the UG3105 driver's version of this code withusing the adc-battery-helper.The API has been designed for easy integration into existing power-supplydrivers. For example this functionality might also be a useful additionto the generic-adc-battery driver.The requirement of needing the adc_battery_helper struct to be the firstmember of a battery driver's data struct is not ideal. This is a compromisewhich is necessary to allow directly using the helper's get_property(),external_power_changed() and suspend()/resume() functions as power-supply /suspend-resume callbacks.Reviewed-by: Linus Walleij Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20250831122942.47875-2-hansg@kernel.orgSigned-off-by: Sebastian Reichel List of files: /linux/drivers/power/supply/Makefile
