 * This file contains the general definitions for the cyclades.c driver
 *$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
