    Add LTC2941/LTC2943 Battery Gauge Driver · 085bc24d

    Both the LTC2941 and LTC2943 measure battery capacity.
    The LTC2943 is compatible with the LTC2941, it adds voltage and
    temperature monitoring, and uses a slightly different conversion
    formula for the charge counter.
    
    To avoid confusion with e.g. the LTC2945, the driver is called
    LTC2941 instead of LTC294X.
    
    v2: Fix units of measurement: uV, uA and centidegrees.
    v3: Correctly set configuration register. Allow negative values
        for the sense resistor.
    v4: Run checkpatch.pl and fix all errors and warnings.
    v5: Prefix "lltc," to devicetree properties.
