-#------------------------------------------------------------
-#@version: cedar_vers0_08
-#@Author : Truby.Zong
-#@Date : 2011-4-06
-#@Description:
-# The second version of cedar video engine driver, which

-#------------------------------------------------------------
-#@version: Vers0_01
-#@Author : Truby.Zong
-#@Date : 2011-3-18
-#@Description:
-# The first version of cedar video engine driver, which
-#handles the irq/clock/phy memory alloc of the cedar device,
-#and also the AV-SYNC counter (AVS_CNT1);
-# Please pay attention to the method to request/remap IO
-#resource and request/free irq, which are just handle once in
-#module init and module exit.
