    Subject[RFC PATCH v3 1/9] dt-bindings: battery: Add temperature-capacity degradation table
    Some charger/battery vendors describe the temperature impact to
    battery capacity by providing tables with capacity change at
    given temperature. Support providing this temperature - capacity
    dependency using the simple-battery DT nodes.
