+description: |
+ The LMP92064 is a two channel ADC intended for combined voltage and current
+ measurements.
+
+ The device contains two ADCs to allow simultaneous sampling of voltage and
+ current and thus of instantanious power consumption.
+
+properties:
+ compatible:
+ enum:
+ - ti,lmp92064
+
+ reg:
+ maxItems: 1
+
+ spi-max-frequency: true
+
+ shunt-resistor:
+ description: |
+ Value of the shunt resistor (in µΩ) connected between INCP and INCN,
+ across which current is measured. Used to provide correct scaling of the
+ raw adc measurement.
+
+ reset-gpios:
+ maxItems: 1
