    power: supply: New driver for LEGO MINDSTORMS EV3 battery · 53db8858

    This adds a new driver for the LEGO MINDSTORMS EV3 battery. The EV3 is
    an embedded ARM device that can use 6 AA batteries or a special rechargeable
    Li-ion battery pack. The rechargeable battery pack presses a special key
    switch in the battery compartment to indicate that it is present.
    
    The EV3 is only capable of monitoring battery voltage and current. The
    charging circuit is built into the rechargeable battery pack and there is
    no way to communicate with is, so we can't provide any information about
    charging status.
    
    When not using the rechargeable battery pack, it is most common to use
    alkaline batteries to power the device, but it is also common for people to
    use rechargeable NiMH batteries. Since there is not a way to automatically
    differentiate between these, the technology property is made writable.
