+1 Release Date    : Sun May 14 22:49:52 PDT 2006 - Sumant Patro <Sumant.Patro@lsil.com>
+2 Current Version : 00.00.03.01
+3 Older Version   : 00.00.02.04
+
+i.      Added support for ZCR controller.
+
+                New device id 0x413 added.
+
+ii.     Bug fix : Disable controller interrupt before firing INIT cmd to FW.
+
+                Interrupt is enabled after required initialization is over.
+                This is done to ensure that driver is ready to handle interrupts when
+                it is generated by the controller.
