    power_supply: Add support for writeable properties · 0011d2d4
    Daniel Mack 提交于
    This patch adds support for writeable power supply properties and
    exposes them as writeable to sysfs.
    
    A power supply implementation must implement two new function calls in
    order to use that feature:
    
      int set_property(struct power_supply *psy,
                       enum power_supply_property psp,
                       const union power_supply_propval *val);
    
      int property_is_writeable(struct power_supply *psy,
                                enum power_supply_property psp);
