Optional properties:
+ - ti,single-shot: This chip has two power modes: single-shot (chip takes one
+ measurement and then shuts itself down) and continuous (
+ chip takes continuous measurements). The continuous mode is
+ more reliable and suitable for hardware monitor type device,
+ but the single-shot mode is more power-friendly and useful
+ for battery-powered device which cares power consumptions
+ while still needs some measurements occasionally.
+ If this property is present, the single-shot mode will be
+ used, instead of the default continuous one for monitoring.
