+Subject: cs5536: add support for IDE controller variant
+
+From: Andrey Korolyov <andrey@xdel.ru>
+
+commit 591b6bb605785c12a21e8b07a08a277065b655a5 upstream.
+
+Several legacy devices such as Geode-based Cisco ASA appliances
+and DB800 development board do possess CS5536 IDE controller
+with different PCI id than existing one. Using pata_generic is
+not always feasible as at least DB800 requires MSR quirk from
+pata_cs5536 to be used with vendor firmware.
