2  * Chip register definitions for PCILynx chipset.  Based on pcilynx.h
3  * from the Linux 1394 drivers, but modified a bit so the names here
4  * match the specification exactly (even though they have weird names,
5  * like xxx_OVER_FLOW, or arbitrary abbreviations like SNTRJ for "sent
6  * reject" etc.)
