|  | *$Log: cyclades.h,v $ | 
|  | *Revision 3.1  2002/01/29 11:36:16  henrique | 
|  | *added throttle field on struct cyclades_port to indicate whether the | 
|  | *port is throttled or not | 
|  | * | 
|  | *Revision 3.1  2000/04/19 18:52:52  ivan | 
|  | *converted address fields to unsigned long and added fields for physical | 
|  | *addresses on cyclades_card structure; | 
|  | * | 
|  | *Revision 3.0  1998/11/02 14:20:59  ivan | 
|  | *added nports field on cyclades_card structure; | 
|  | * | 
|  | *Revision 2.5  1998/08/03 16:57:01  ivan | 
|  | *added cyclades_idle_stats structure; | 
|  | * | 
|  | *Revision 2.4  1998/06/01 12:09:53  ivan | 
|  | *removed closing_wait2 from cyclades_port structure; | 
|  | * | 
|  | *Revision 2.3  1998/03/16 18:01:12  ivan | 
|  | *changes in the cyclades_port structure to get it closer to the | 
|  | *standard serial port structure; | 
|  | *added constants for new ioctls; | 
|  | * | 
|  | *Revision 2.2  1998/02/17 16:50:00  ivan | 
|  | *changes in the cyclades_port structure (addition of shutdown_wait and | 
|  | *chip_rev variables); | 
|  | *added constants for new ioctls and for CD1400 rev. numbers. | 
|  | * | 
|  | *Revision 2.1	1997/10/24 16:03:00  ivan | 
|  | *added rflow (which allows enabling the CD1400 special flow control | 
|  | *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to | 
|  | *cyclades_port structure; | 
|  | *added Alpha support | 
|  | * | 
|  | *Revision 2.0  1997/06/30 10:30:00  ivan | 
|  | *added some new doorbell command constants related to IOCTLW and | 
|  | *UART error signaling | 
|  | * | 
|  | *Revision 1.8  1997/06/03 15:30:00  ivan | 
|  | *added constant ZFIRM_HLT | 
|  | *added constant CyPCI_Ze_win ( = 2 * Cy_PCI_Zwin) | 
|  | * | 
|  | *Revision 1.7  1997/03/26 10:30:00  daniel | 
|  | *new entries at the end of cyclades_port struct to reallocate | 
|  | *variables illegally allocated within card memory. | 
|  | * | 
|  | *Revision 1.6  1996/09/09 18:35:30  bentson | 
|  | *fold in changes for Cyclom-Z -- including structures for | 
|  | *communicating with board as well modest changes to original | 
|  | *structures to support new features. | 
|  | * | 
|  | *Revision 1.5  1995/11/13 21:13:31  bentson | 
|  | *changes suggested by Michael Chastain <mec@duracef.shout.net> | 
|  | *to support use of this file in non-kernel applications |
