Max17043/17044 have a pin for alert host about low level state of charge and this alert can be configured in a threshold from 1% up to 32% of SOC. Tested on Toradex Colibri iMX7D, with a SparkFun Lipo Fuel Gauge module based on MAXIM MAX17043. Thanks Krzysztof for your time reviewing it. Let me know what you think about the fixes. Changes since v5: (Suggested by Krzysztof Kozlowski) - Rearrange code and add max17040_enable_alert_irq on patch 1/5 - Remove useless dev_info Changes since v4: (Suggested by Krzysztof Kozlowski) - Fix code style and alignment issues - Keep IRQF_TRIGGER_FALLING | IRQF_ONESHOT instead client->flags (Suggested by Rob Herring) - Add reference to the MFD description - Fix the dt-bindings commit description Matheus Castello (5): power: supply: max17040: Add IRQ handler for low SOC alert dt-bindings: power: supply: Max17040: Add DT bindings for max17040 fuel gauge devicetree: mfd: max14577: Add reference to max14040_battery.txt descriptions power: supply: max17040: Config alert SOC low level threshold from FDT power: supply: max17040: Send uevent in SOC and status change .../devicetree/bindings/mfd/max14577.txt | 2 + .../power/supply/max17040_battery.txt | 33 ++++ drivers/power/supply/max17040_battery.c | 141 +++++++++++++++++- 3 files changed, 171 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/power/supply/max17040_battery.txt -- 2.24.0.rc2
