+Description:
+		Writing a device location to this file will cause
+		the driver to attempt to bind to the device found at
+		this location. The format for the location is Object.Id
+		and is the same as found in /sys/bus/fsl-mc/devices/.
+                For example:
+		# echo dpni.2 > /sys/bus/fsl-mc/drivers/fsl_dpaa2_eth/bind
