- *	linux/drivers/sbus/char/aurora.c -- Aurora multiport driver
- *
- *	Copyright (c) 1999 by Oliver Aldulea (oli at bv dot ro)
- *
- *	This code is based on the RISCom/8 multiport serial driver written
- *	by Dmitry Gorodchanin (pgmdsg@ibi.com), based on the Linux serial
- *	driver, written by Linus Torvalds, Theodore T'so and others.
- *	The Aurora multiport programming info was obtained mainly from the
- *	Cirrus Logic CD180 documentation (available on the web), and by
- *	doing heavy tests on the board. Many thanks to Eddie C. Dost for the
- *	help on the sbus interface.
- *

- *	it under the terms of the GNU General Public License as published by

- *	(at your option) any later version.
- *
- *	This program is distributed in the hope that it will be useful,
- *	but WITHOUT ANY WARRANTY; without even the implied warranty of
- *	MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
- *	GNU General Public License for more details.
- *
- *	You should have received a copy of the GNU General Public License
- *	along with this program; if not, write to the Free Software
- *	Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- *	Revision 1.0
- *
- *	This is the first public release.
- *
- *	Most of the information you need is in the aurora.h file. Please
- *	read that file before reading this one.
- *
- *	Several parts of the code do not have comments yet.
- * 
- * n.b.  The board can support 115.2 bit rates, but only on a few
- * ports. The total badwidth of one chip (ports 0-7 or 8-15) is equal
- * to OSC_FREQ div 16. In case of my board, each chip can take 6
- * channels of 115.2 kbaud.  This information is not well-tested.
- * 
- * Fixed to use tty_get_baud_rate().
- *   Theodore Ts'o <tytso@mit.edu>, 2001-Oct-12

- *	linux/drivers/sbus/char/aurora.h -- Aurora multiport driver
- *
- *	Copyright (c) 1999 by Oliver Aldulea (oli@bv.ro)
- *
- *	This code is based on the RISCom/8 multiport serial driver written
- *	by Dmitry Gorodchanin (pgmdsg@ibi.com), based on the Linux serial
- *	driver, written by Linus Torvalds, Theodore T'so and others.
- *	The Aurora multiport programming info was obtained mainly from the
- *	Cirrus Logic CD180 documentation (available on the web), and by
- *	doing heavy tests on the board. Many thanks to Eddie C. Dost for the
- *	help on the sbus interface.

- *	but WITHOUT ANY WARRANTY; without even the implied warranty of
- *	MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
- *	GNU General Public License for more details.
- *
- *	You should have received a copy of the GNU General Public License
- *	along with this program; if not, write to the Free Software
- *	Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- *	Revision 1.0
- *
- *	This is the first public release.
- *
- *	This version needs a lot of feedback. This is the version that works
- *	with _my_ board. My board is model 1600se, revision '@(#)1600se.fth
- *	1.2 3/28/95 1'. The driver might work with your board, but I do not
- *	guarantee it. If you have _any_ type of board, I need to know if the
- *	driver works or not, I need to know exactly your board parameters
- *	(get them with 'cd /proc/openprom/iommu/sbus/sio16/; ls *; cat *')
- *	Also, I need your board revision code, which is written on the board.
- *	Send me the output of my driver too (it outputs through klogd).
- *
- *	If the driver does not work, you can try enabling the debug options
- *	to see what's wrong or what should be done.
- *
- *	I'm sorry about the alignment of the code. It was written in a
- *	128x48 environment.
- *
- *	I must say that I do not like Aurora Technologies' policy. I asked
- *	them to help me do this driver faster, but they ended by something
- *	like "don't call us, we'll call you", and I never heard anything
- *	from them. They told me "knowing the way the board works, I don't
- *	doubt you and others on the net will make the driver."
- *	The truth about this board is that it has nothing intelligent on it.
- *	If you want to say to somebody what kind of board you have, say that
- *	it uses Cirrus Logic processors (CD180). The power of the board is
- *	in those two chips. The rest of the board is the interface to the
- *	sbus and to the peripherals. Still, they did something smart: they
- *	reversed DTR and RTS to make on-board automatic hardware flow
- *	control usable.
- *	Thanks to Aurora Technologies for wasting my time, nerves and money.
