    Subject[PATCH v4 02/18] power: supply: power_supply_core: add constant-charge-current optional property
    Date
    This adds the constant-charge-current property to the list of optional
    properties for the battery.

    The constant charge current is critical for batteries as they can't
    handle all charge currents.

    Signed-off-by: Quentin Schulz <quentin.schulz@free-electrons.com>

    v4:
    - switch from constant-charge-current-microamp to constant-charge-microamp,

    added in v3
