+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
+
+  reg:
+    maxItems: 1
+
+  vref-supply:
+    description:
+      Device tree identifier of the regulator that provides the external
+      reference voltage.
+    maxItems: 1
+
+  spi-max-frequency:
+    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.
+    maxItems: 1
+
+required:
+  - compatible
+  - reg
+  - vref-supply
+
+examples:
+  - |
+    #include <dt-bindings/gpio/gpio.h>
+    spi0 {
+        adc@0 {
