+title: Maxim MAX6650 and MAX6651 I2C Fan Controllers
+
+maintainers:

+
+description: |
+  The MAX6650 and MAX6651 regulate and monitor the speed
+  of 5VDC/12VDC burshless fans with built-in tachometers.
+
+  Datasheets:
+    https://datasheets.maximintegrated.com/en/ds/MAX6650-MAX6651.pdf

+  compatible:
+    enum:
+      - maxim,max6650
+      - maxim,max6651
+
+  reg:
+    maxItems: 1
+
+  maxim,fan-microvolt:
+    description:
+      The supply voltage of the fan, either 5000000 uV or
+      12000000 uV.
+    enum: [5000000, 12000000]
+
+  maxim,fan-prescale:
+    description:
+      Pre-scaling value, as per datasheet. Lower values
+      allow more fine-grained control of slower fans.
+    $ref: /schemas/types.yaml#/definitions/uint32
+    enum: [1, 2, 4, 8, 16]
+
+  maxim,fan-target-rpm:
+    description:
+      Initial requested fan rotation speed. If specified, the
+      driver selects closed-loop mode and the requested speed.
+      This ensures the fan is already running before userspace
+      takes over.
