From 8d72c796c9d966b0efc26092dae7005c345b3efa Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Fri, 11 Dec 2009 16:16:36 -0800 Subject: omap1: LCD_DMA: Use some define rather than a hexadecimal The patch corrects the issue introduced with one of my earlier patches: OMAP: DMA: Fix omapfb/lcdc on OMAP1510 broken when PM set[1] as pointed out by OMAP subsystem maintainer. Applies on top of my prevoius patch: OMAP: DMA: move LCD DMA related code from plat-omap to mach-omap1[2] Tested on Amstrad Delta Compile tested with omap_generic_2420_defconfig [1] http://patchwork.kernel.org/patch/57922/ [2] http://patchwork.kernel.org/patch/61952/ Signed-off-by: Janusz Krzysztofik Signed-off-by: Tony Lindgren --- arch/arm/mach-omap1/include/mach/lcdc.h | 57 +++++++++++++++++++++++++++++++++ arch/arm/mach-omap1/lcd_dma.c | 3 +- 2 files changed, 59 insertions(+), 1 deletion(-) create mode 100644 arch/arm/mach-omap1/include/mach/lcdc.h (limited to 'arch/arm/mach-omap1') diff --git a/arch/arm/mach-omap1/include/mach/lcdc.h b/arch/arm/mach-omap1/include/mach/lcdc.h new file mode 100644 index 000000000000..89bd703adaf6 --- /dev/null +++ b/arch/arm/mach-omap1/include/mach/lcdc.h @@ -0,0 +1,57 @@ +/* + * arch/arm/mach-omap1/include/mach/lcdc.h + * + * Extracted from drivers/video/omap/lcdc.c + * Copyright (C) 2004 Nokia Corporation + * Author: Imre Deak + * + * 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.
