As thinkpad_acpi has to use the 'struct power_supply' created by the generic ACPI driver it has to rely on custom sysfs attributes instead of proper power_supply properties to implement this property. Patch 1: Adds the power_supply documentation and basic public API Patch 2: Adds helpers to power_supply core to help drivers implement the charge_behaviour attribute Patch 3: Adds support for force-discharge to thinkpad_acpi. Patch 4: Adds support for inhibit-discharge to thinkpad_acpi. Patch 3 and 4 are largely taken from other patches and adapted to the new API. (Links are in the patch trailer) Ognjen Galic, Nicolo' Piazzalunga, Thomas Koch: Your S-o-b is on the original inhibit_charge and force_discharge patches. I would like to add you as Co-developed-by but to do that it will also require your S-o-b. Could you give your sign-offs for the new patches, so you can be properly attributed? Sebastian Reichel: Currently the series does not actually support the property as a proper powersupply property handled fully by power_supply_sysfs.c because there would be no user for this property.
