power: supply: Add new Intel Dollar Cove TI battery driver

2025-09-05T23:50:01+00:00

Intel 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 already supported by the axp288_charger / axp288_fuel_gauge drivers. The other "Dollar Cove" PMIC is made by TI and does not have any clear TI denomination, its MFD driver calls it the "Intel Dollar Cove TI PMIC". The Intel Dollar Cove TI PMIC comes with a coulomb-counters with limited functionality which is intended to work together with an always on micro-controller monitoring it for fuel-gauge functionality. Most devices with the Dollar Cove TI PMIC have full-featured fuel-gauge functionality exposed through ACPI with the information coming from either the embedded-controller or a separate full-featured fuel-gauge IC. But some designs lack this, add a battery-monitoring driver using the PMIC's coulomb-counter combined with the adc-battery-helper for capacity estimation for these designs. Register definitions were taken from kernel/drivers/platform/x86/dc_ti_cc.c from 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/downloads Reviewed-by: Linus Walleij Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20250831122942.47875-6-hansg@kernel.org Signed-off-by: Sebastian Reichel

power: supply: Add adc-battery-helper

2025-09-05T23:50:01+00:00

The TI PMIC used on some Intel Bay/Cherry Trail systems has some builtin fuel-gauge functionality which just like the UG3105 fuel-gauge is not a full featured autonomous fuel-gauge. These fuel-gauges offer accurate current and voltage measurements but their coulomb-counters are intended to work together with an always on micro-controller monitoring the fuel-gauge. Add an adc-battery-helper offering open-circuit-voltage (ocv) and through that capacity estimation for devices where such limited functionality fuel-gauges are exposed directly to Linux. This is a copy of the existing UG3105 estimating code, generalized so that it can be re-used in other drivers. The next commit will replace the UG3105 driver's version of this code with using the adc-battery-helper. The API has been designed for easy integration into existing power-supply drivers. For example this functionality might also be a useful addition to the generic-adc-battery driver. The requirement of needing the adc_battery_helper struct to be the first member of a battery driver's data struct is not ideal. This is a compromise which is necessary to allow directly using the helper's get_property(), external_power_changed() and suspend()/resume() functions as power-supply / suspend-resume callbacks.
