[1/1] dt-bindings: power: supply: sc27xx-fg: add low voltage alarm IRQ commit: 17656d2215c3978bbe2811a5e249cd07fe3de77f Best regards,

The SC27XX fuel gauge supports a low voltage alarm IRQ, which is used for more accurate battery capacity measurements with lower voltages. This was unfortunately never documented in bindings, do so now.
