    power: supply: axp20x_battery: add DT support for battery max constant charge current · c8003844
    Quentin Schulz authored
    This adds the ability to set the maximum constant charge current,
    supported by the battery, delivered by this battery power supply to the
    battery.
    
    The maximum constant charge current set in DT will also set the default
    constant charge current supplied by this supply.
    
    The actual user can modify the constant charge current within the range
    of 0 to maximum constant charge current via sysfs.
    The user can also modify the maximum constant charge current to widen
    the range of possible constant charge current. While this seems quite
    risky, a message is printed on the console to warn the user this might
    damage the battery. The reason for letting the user change the maximum
    constant charge current is for letting users change the battery and
    thus, let them adjust the maximum constant charge current according to
    what the battery can support.
