+title: Buffalo Linkstation poweroff driver
+
+maintainers:
+  - Daniel González Cabanelas <dgcbueu@gmail.com>
+
+description: |
+  This driver is used to add the power off function to some Buffalo 
+  LinkStations (ARM MVEBU boards). They use a LED output pin at the 
+  ethernet PHY to inform the board if the power off operation must be
+  performed after restarting.
+
+  When the power-off handler is called, the ethernet PHY LED2 ouptut is
+  set to OFF. If the restart command is executed then the PHY LED2 output
+  is asserted to ON.
+
+properties:
+  compatible:
+    const: linkstation,power-off
+
+  phy-handle,led:
+    description: Phandle to a node of the ethernet PHY used for the power 
+      function. If this optional property is not specified, then the first
+      PHY found in the MDIO bus will be used.
+    $ref: /schemas/types.yaml#/definitions/phandle

+    poweroff {
+        compatible = "linkstation,power-off";
