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.
