    power: supply: Add power_supply_set_input_current_limit_from_supplier helper · c3142dd8
    Hans de Goede 提交于
    On some devices the USB Type-C port power (USB PD 2.0) negotiation is
    done by a separate port-controller IC, while the current limit is
    controlled through another (charger) IC.
    
    It has been decided to model this by modelling the external Type-C
    power brick (adapter/charger) as a power-supply class device which
    supplies the charger-IC, with its voltage-now and current-max representing
    the negotiated voltage and max current draw.
    
    This commit adds a power_supply_set_input_current_limit_from_supplier
    helper function which charger power-supply drivers can call to get
    the max-current from their supplier and have this applied
    through their set_property call-back to their input-current-limit.
