+  an I2C interface.

+
+  ti,shunt-gain:
+    description: |
+      Programmable gain divisor for the shunt voltage accuracy and range. This
+      property only applies to devices that have configurable PGA/ADCRANGE. The
+      gain value is used configure the gain and to convert the shunt voltage,
+      current and power register values when reading measurements from the
+      device.
+
+      For devices that have a configurable PGA (e.g. INA209, INA219, INA220),
+      the gain value maps directly with the PG bits of the config register.
+
+      For devices that have ADCRANGE configuration (e.g. INA238) a shunt-gain
+      value of 1 maps to ADCRANGE=1 where no gain divisor is applied to the
+      shunt voltage, and a value of 4 maps to ADCRANGE=0 such that a wider
+      voltage range is used.
+
+      The default value is device dependent, and is defined by the reset value
+      of PGA/ADCRANGE in the respective configuration registers.
