+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.
