From aa944aa3453e47706685bc562711a9e87375941e Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 16 Dec 1997 06:06:25 +0000 Subject: Merge with Linux 2.1.72, part 2. The new signal code with exception of the code for the rt signals. The definitions in and are currently just stolen from the Alpha and will need to be overhauled. --- drivers/char/cd1865.h | 263 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 263 insertions(+) create mode 100644 drivers/char/cd1865.h (limited to 'drivers/char/cd1865.h') diff --git a/drivers/char/cd1865.h b/drivers/char/cd1865.h new file mode 100644 index 000000000..e7407f4b8 --- /dev/null +++ b/drivers/char/cd1865.h @@ -0,0 +1,263 @@ +/* + * linux/drivers/char/cd1865.h -- Definitions relating to the CD1865 + * for the Specialix IO8+ multiport serial driver. + * + * Copyright (C) 1997 Roger Wolff (R.E.Wolff@BitWizard.nl) + * Copyright (C) 1994-1996 Dmitry Gorodchanin (begemot@bgm.rosprint.net) + * + * Specialix pays for the development and support of this driver. + * Please DO contact io8-linux@specialix.co.uk if you require + * support. + * + * This driver was developped in the BitWizard linux device + * driver service.
