+description: |
+ Bindings for the max1241 12-bit, single-channel ADC device. This
+ driver supports voltage reading and can optionally be configured for
+ power-down mode operation. The datasheet can be found at:
+ https://datasheets.maximintegrated.com/en/ds/MAX1240-MAX1241.pdf
+
+properties:
+ compatible:
+ enum:
+ - maxim,max1241

+ vref-supply:
+ description:
+ Device tree identifier of the regulator that provides the external
+ reference voltage.
+ maxItems: 1
+
+ shdn-gpios:
+ description:
+ GPIO spec for the GPIO pin connected to the ADC's /SHDN pin. If
+ specified, the /SHDN pin will be asserted between conversions,
+ thus enabling power-down mode.
