From 436d42c61c3eef1d02256174c8615046c61a28ad Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 24 Aug 2012 15:22:12 +0200 Subject: ARM: samsung: move platform_data definitions Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories. This moves such data out of the samsung include directories Signed-off-by: Arnd Bergmann Acked-by: Mark Brown Acked-by: Greg Kroah-Hartman Acked-by: Nicolas Pitre Acked-by: Mauro Carvalho Chehab Cc: Kukjin Kim Cc: Kyungmin Park Cc: Ben Dooks Cc: Jeff Garzik Cc: Guenter Roeck Cc: "Wolfram Sang (embedded platforms)" Cc: Dmitry Torokhov Cc: Bryan Wu Cc: Richard Purdie Cc: Sylwester Nawrocki Cc: Chris Ball Cc: David Woodhouse Cc: Grant Likely Cc: Felipe Balbi Cc: Alan Stern Cc: Sangbeom Kim Cc: Liam Girdwood Cc: linux-samsung-soc@vger.kernel.org --- include/linux/platform_data/i2c-s3c2410.h | 77 +++++++++++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 include/linux/platform_data/i2c-s3c2410.h (limited to 'include/linux/platform_data/i2c-s3c2410.h') diff --git a/include/linux/platform_data/i2c-s3c2410.h b/include/linux/platform_data/i2c-s3c2410.h new file mode 100644 index 000000000000..51d52e767a19 --- /dev/null +++ b/include/linux/platform_data/i2c-s3c2410.h @@ -0,0 +1,77 @@ +/* arch/arm/plat-s3c/include/plat/iic.h + * + * Copyright 2004-2009 Simtec Electronics + * Ben Dooks + * + * S3C - I2C Controller platform_device info + * + * This program 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. +*/ + +#ifndef __ASM_ARCH_IIC_H +#define __ASM_ARCH_IIC_H __FILE__ + +#define S3C_IICFLG_FILTER (1<<0) /* enable s3c2440 filter */ + +/** + * struct s3c2410_platform_i2c - Platform data for s3c I2C. + * @bus_num: The bus number to use (if possible). + * @flags: Any flags for the I2C bus (E.g.
