+Forwarded: http://mid.gmane.org/1379298957.23881.10.camel@deadeye.wl.decadent.org.uk
+
+Matt Taggart reported that mvsas didn't bind to the Marvell
+SAS controller on a Supermicro AOC-SAS2LP-MV8 board.
+
+lspci reports it as:
+
+01:00.0 RAID bus controller [0104]: Marvell Technology Group Ltd. Device [1b4b:9485] (rev 03)
+        Subsystem: Marvell Technology Group Ltd. Device [1b4b:9485]
+[...]
+
+Add it to the device table as chip_9485.
