maxItems: 1
avcc-supply:
description:
Phandle to the Avcc power supply
shunt-resistor-micro-ohms:
description:
The value of current sense resistor in microohms. If not provided,
the current reading and overcurrent alert is disabled.
adi,shutdown-threshold-microamp:
description:
Specifies the current level at which an over current alert occurs.
If not provided, the overcurrent alert is configured to max ADC range
based on shunt-resistor-micro-ohms.
adi,vrange-high-enable:
description:
Specifies which internal voltage divider to be used. A 1 selects
a 7:2 voltage divider while a 0 selects a 14:1 voltage divider.
