+description: |
+ Some Buffalo LinkStations (ARM MVEBU boards) use an output pin at the ethernet
+ PHY (LED2/INTn) to inform the board if the power off operation must be performed
+ at restart time. This pin is ORed with the power switch and allows the WOL
+ function to be also used.
+
+ When the power-off handler is called, the ethernet PHY INTn ouptut is set to
+ LOW state. If the restart command is executed then the PHY INTn output is
+ forced to HIGH state.
