From bc4c4f45acbe1f1528d654b0b1793f25c175bf8f Mon Sep 17 00:00:00 2001 From: Hans-Jürgen Koch Date: Fri, 2 Mar 2007 13:03:12 +0100 Subject: UIO: Hilscher CIF card driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit this is a patch that adds support for Hilscher CIF DeviceNet and Profibus cards. I tested it on a Kontron CPX board, and Thomas reviewed it. You can find the user space part here: http://www.osadl.org/projects/downloads/UIO/user/cif-0.1.0.tar.gz Notes: cif_api.c is the main file you want to look at. It contains the functions to open, close, mmap and so on. cif_dps.c adds functions specific to Profibus cards, and cif_dn.c contains functions for DeviceNet cards. cif.c is a universal playground, it's just a small test program. The user space part of this UIO driver is still work in progress, and not everything is tested yet. At the moment, the thread in cif_api.c contains some code that artificially makes the card generate interrupts, this was added for testing and will be removed later. But the driver already contains all the functions needed for useful operation, so it gives a good idea of how such a thing looks like. For comparison, here's what you get from the manufacturer (www.hilscher.com) when you ask for a Linux 2.6 driver: http://www.tglx.de/private/hjk/cif-orig-2.6.tar.bz2 WARNING: Don't look at the code for too long, you might become sick :-) Signed-off-by: Hans-Jürgen Koch Signed-off-by: Greg Kroah-Hartman --- drivers/uio/Kconfig | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'drivers/uio/Kconfig') diff --git a/drivers/uio/Kconfig b/drivers/uio/Kconfig index 6b1a62d45e46..b778ed71f636 100644 --- a/drivers/uio/Kconfig +++ b/drivers/uio/Kconfig @@ -13,4 +13,17 @@ config UIO If you don't know what to do here, say N. +config UIO_CIF + tristate "generic Hilscher CIF Card driver" + depends on UIO && PCI + default n + help + Driver for Hilscher CIF DeviceNet and Profibus cards.
