+maintainers:
+  - Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
+
+description:
+  The Maxim MAX6958/6959 7-segment LED display controller provides
+  an I2C interface to up to four 7-segment LED digits. The MAX6959
+  in comparison to MAX6958 has the debounce and interrupt support.
+  Type of the chip can be autodetected via specific register read,
+  and hence the features may be enabled in the driver at run-time.
+  Given hardware is simple and does not provide any additional pins,
+  such as reset or enable.
+
+properties:
+  compatible:
+    const: maxim,max6959
+
+  reg:
+    maxItems: 1
+
+required:
+  - compatible
+  - reg
+
+additionalProperties: false
+
+examples:
+  - |
+    i2c {
+        #address-cells = <1>;
+        #size-cells = <0>;
+
+        display-controller@38 {
+            compatible = "maxim,max6959";
+            reg = <0x38>;
