+title: Mediatek's regulator vibrator device tree bindings
+
+maintainer:

+
+description: |
+  Registers a regulator device as vibrator, where the on/off capability is controlled by a regulator.
+
+properties:
+  compatible:
+      const: "regulator-vibrator"
+
+	vibr-supply:
+		description: Power supply to the vibrator.
+		refs:Documentation/devicetree/bindings/regulator/regulator.txt for details.
+
+  max-volt:
+    description: The maximum voltage value supplied to the vibrator regulator.
+    						 The unit of the voltage is micro.
+
+  min-volt:
+    description: The minimum voltage value supplied to the vibrator regulator.
+    						 The unit of the voltage is micro.
+
+  min-limit:
+    description: The minimum duration time in ms for vibrator, default is 15ms.
+    						 If user request smaller duration, the default value will be used
+    						 instead. The default value comes from the smallest unit that can
+    						 be sensored.
+
+  max-limit:
+    description: The maximum duration time in ms for vibrator. If not set, it means
+    						 no max limitation.
