9 - ti,single-shot: This chip has two power modes: single-shot (chip takes one
13 but the single-shot mode is more power-friendly and useful
14 for battery-powered device which cares power consumptions
16 If this property is present, the single-shot mode will be
22 - #address-cells: Required only if a child node is present. Must be 1.
23 - #size-cells: Required only if a child node is present. Must be 0.
27 - reg: Must be 0, 1 or 2, corresponding to IN1, IN2 or IN3 port of INA3221
