From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! --- include/asm-arm/arch-imx/dma.h | 71 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 include/asm-arm/arch-imx/dma.h (limited to 'include/asm-arm/arch-imx/dma.h') diff --git a/include/asm-arm/arch-imx/dma.h b/include/asm-arm/arch-imx/dma.h new file mode 100644 index 00000000000..dbdc0178041 --- /dev/null +++ b/include/asm-arm/arch-imx/dma.h @@ -0,0 +1,71 @@ +/* + * linux/include/asm-arm/imxads/dma.h + * + * Copyright (C) 1997,1998 Russell King + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (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.
