Subject[PATCH 0/4] power: supply: add charge_behaviour property (force-discharge, inhibit-charge)
Date
Hi,

this series adds support for the charge_behaviour property to the power
subsystem and thinkpad_acpi driver.

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.
