+
+description:
+  The MAX16150/MAX16169 is a low-power pushbutton on/off controller with a
+  switch debouncer and built-in latch. It accepts a noisy input from a
+  mechanical switch and produces a clean latched output, as well as a one-shot
+  interrupt output.
+
+properties:
+  compatible:
+    description:
+      Specifies the supported device variants. The MAX16150 and MAX16169 are supported.
+    enum:
+      - adi,max16150a
+      - adi,max16150b
+      - adi,max16169a
+      - adi,max16169b
+
+  interrupt-gpio:
+    maxItems: 1
+
+  clr-gpios:
+    description:
+      Clear Input. Pulling CLR low deasserts the latched OUT signal. If OUT is
+      already deasserted when CLR is pulled low, the state of OUT is unchanged.
+    maxItems: 1
