/* $Revision: 1.1 $$Date: 2004-01-28 15:25:07 $
* linux/include/linux/cyclades.h
*
* This file was initially written by
* Randolph Bentson <bentson@grieg.seaslug.org> and is maintained by
* Ivan Passos <ivan@cyclades.com>.
*
* This file contains the general definitions for the cyclades.c driver
*$Log: not supported by cvs2svn $
*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
