field on struct cyclades_port to indicate whether the 12 *port is throttled or not 13 * 14 *Revision 3.1 2000/04/19 18:52:52 ivan 15 *converted address fields to unsigned long and added fields for physical 16 *addresses on cyclades_card structure; 17 * 18 *Revision 3.0 1998/11/02 14:20:59 ivan 19 *added nports field on cyclades_card structure; 20 * 21 *Revision 2.5 1998/08/03 16:57:01 ivan 22 *added cyclades_idle_stats structure; 23 * 24 *Revision 2.4 1998/06/01 12:09:53 ivan 25 *removed closing_wait2 from cyclades_port structure; 26 * 27 *Revision 2.3 1998/03/16 18:01:12 ivan 28 *changes in the cyclades_port structure to get it closer to the 29 *standard serial port structure; 30 *added constants for new ioctls; 31 * 32 *Revision 2.2 1998/02/17 16:50:00 ivan 33 *changes in the cyclades_port structure (addition of shutdown_wait and 34 *chip_rev variables); 35 *added constants for new ioctls and for CD1400 rev. numbers. 36 * 37 *Revision 2.1 1997/10/24 16:03:00 ivan 38 *added rflow (which allows enabling the CD1400 special flow control 39 *feature) and rtsdtr_inv (which allows DTR/RTS pin inversion) to 40 *cyclades_port structure; 41 *added Alpha support 42 * 43 *Revision 2.0 1997/06/30 10:30:00 ivan 44 *added some new doorbell command constants related to IOCTLW and 45 *UART error signaling 46 * 47 *Revision 1.8 1997/06/03 15:30:00 ivan 48 *added constant ZFIRM_HLT 49 *added constant CyPCI_Ze_win ( = 2 * Cy_PCI_Zwin) 50 * 51 *Revision 1.7 1997/03/26 10:30:00 daniel 52 *new entries at the end of cyclades_port struct to reallocate 53 *variables illegally allocated within card memory. 54 * 55 *Revision 1.6 1996/09/09 18:35:30 bentson 56 *fold in changes for Cyclom-Z -- including structures for 57 *communicating with board as well modest changes to original 58 *structures to support new features. 59 * 60 *Revision 1.5 1995/11/13 21:13:31 bentson 61 *changes suggested by Michael Chastain <mec@duracef.shout.net> 62 *to support use of this file in non-kernel
