From 80ff0fd3ab6451407a20c19b80c1643c4a6d6434 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 5 May 2009 17:35:21 -0700 Subject: Staging: Add octeon-ethernet driver files. The octeon-ethernet driver supports the sgmii, rgmii, spi, and xaui ports present on the Cavium OCTEON family of SOCs. These SOCs are multi-core mips64 processors with existing support over in arch/mips. The driver files can be categorized into three basic groups: 1) Register definitions, these are named cvmx-*-defs.h 2) Main driver code, these have names that don't start cvmx-. 3) Interface specific functions and other utility code, names starting with cvmx- Signed-off-by: David Daney Signed-off-by: Ralf Baechle --- drivers/staging/octeon/ethernet-proc.c | 256 +++++++++++++++++++++++++++++++++ 1 file changed, 256 insertions(+) create mode 100644 drivers/staging/octeon/ethernet-proc.c (limited to 'drivers/staging/octeon/ethernet-proc.c') diff --git a/drivers/staging/octeon/ethernet-proc.c b/drivers/staging/octeon/ethernet-proc.c new file mode 100644 index 0000000..8fa88fc --- /dev/null +++ b/drivers/staging/octeon/ethernet-proc.c @@ -0,0 +1,256 @@ +/********************************************************************** + * Author: Cavium Networks + * + * Contact: support@caviumnetworks.com + * This file is part of the OCTEON SDK + * + * Copyright (c) 2003-2007 Cavium Networks + * + * This file is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License, Version 2, as + * published by the Free Software Foundation. + * + * This file is distributed in the hope that it will be useful, but + * AS-IS and WITHOUT ANY WARRANTY; without even the implied warranty + * of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE, TITLE, or + * NONINFRINGEMENT.
